RELEASE NOTES

Release notes 1.81a

Driver for all supported cards. Includes 1825 audio drivers for Windows 10. Unlike previous releases, the 1825 audio driver will only work in Windows 10.

Driver changes:

  • Windows 10: Updated audio driver to 1825 (built date: 22 ‎June ‎2016, made by C-Media).
  • Updated C-Media Panel.

Other notes:

  • Replaced C-Media driver uninstaller with UNi Xonar driver cleaner.

Rev. 2 changes:

  • Added support for STXII cards in Asus Audio Center, cards will be detected as STX by Asus Audio Center but feature wise almost everything should be there.

Known issues:

  • 1825 audio drivers have an issue when the audio card is uninstalled, disabled or the drivers are overwritten, resulting in a system crash. In order to avoid the uninstall system crash I’ve come up with a workaround  that’s presented below
  • Asus Audio Center: GX button is no longer showing. It has to do with 1825 audio drivers and there may be a reason why C-Media removed it. I’m not sure if it’s worth it to bring the GX on/off control back.
  • STX II:  Asus Audio Center is missing the gain 16/32 ohms for headset.
  • The 1825 audio driver has a considerably higher DPC latency than previous drivers. Original report.

Possible issues:

  • STX II: XonarSwitch might not work. Need more feedback on this.
  • Audio playback through headphones and SPDIF at the same time isn’t possible anymore. Original report. Need more confirmations.
  • DSX & probably other cards: DTS Connect with 5.1 speakers does not work. Original report. Need more confirmations.
  • There are reports that the sound quality of these audio drivers is different. I’ve yet to do the investigations related to this topic.

How to uninstall 1825 v1.81 drivers: In order to avoid a system crash while uninstalling 1825 drivers you will need to play an audio file before proceeding with the uninstall process. Restart system after the uninstall process is done.

 

Release notes 1.80

UNi Xonar installer changes:

  • Added DPI interface scaling to the installer.
  • Added card autodetection and if the audio card is not detected it will show an error message with possible reasons for that.
  • Improved driver cleaning. It uninstalls all copies of the Xonar/C-media CMI8788 drivers that are present in the Windows driver repository. By installing drivers with “Run driver cleaning” option you won’t be able to use “Roll Back Driver” option for the audio card in Device Manager.
  • Changed the driver installation procedure. Added a fail safe driver installer that should help in those cases where you were required to manually install the audio driver or install it in safe mode. Silent installation is always on and its user option has been removed. If standard driver installation gets stuck (does not finish after 100 sec) it is automatically closed. If standard driver installer fails to install the drivers then an alternate driver installer is launched. If that fails too, you will get notified by the installer that driver installation failed.

Driver changes:

  • Windows XP: Added support for other CMI8788 cards.
  • Xonar DG, DGX, DG SI: Front Panel jack detection should now work if it did with the original drivers.
  • Fixed GX not being turned off by default in “Normal” configuration for the following cards Xonar D2, D2X, DG, DGX and DG SI.

Rev. 2 changes:

  • Improved and fixed some problems with the new driver installation procedure.
  • Added different messages based on why installation failed.
  • Fixed “Front Panel Microphone” not working by default.

Rev. 3 changes:

  • Increased the delay between driver cleaning and driver installation procedures. Might help in some installation failing cases.
  • Fixed the “Warning: Windows running in Test Mode or with Disable Driver Signature Enforcement is required!” message not showing up if needed in combination with the detected audio card.

The 1.80 drivers come in two variants:

  • 1.80a “Standard”

Driver for all supported cards. Replacement for 1.75a driver. Includes 1816 audio drivers for Win XP and 1823 audio drivers for Windows Vista/7/8/8.1/10.

Driver changes:

  • Windows Vista/7/8/8.1/10: Updated audio driver to 1823 (built date: 2 Jun 2015, made by C-Media).
  • Includes updated driver installer, ASUS Audio Center and C-Media Panel.

Other notes:

  • 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.
  • Xonar STX II cards: Drivers work with STXII cards but the changing audio settings may not work with ASUS Audio Center and only with C-Media Panel. Installation on Windows Vista/7/8.1/10 x64 requires Windows running in Test Mode or with “Disable Driver Signature Enforcement” option.

Known issues:

  • STXII: Asus Audio Center does not work. You need to download this patched version and copy paste it over “C:\Program Files\UNi Xonar Audio\Customapp\”.

Possible issues:

  • Microphone stops working if running specific programs. If you run into this issue please report it in a reply to the original report. If you run into the issue you can switch to v1.75a drivers or connect the microphone to the onboard audio card microphone input.
  • WASAPI playback issues might occur with some soundcards
  • Occasionally when waking PC up from sleep the Xonar card does not output any sound.
  • Drivers might stop installing on Windows 10. Try 1.75a, 1.80b or 1.81a instead.
  • 1.80b “STXII”

Driver maily for STX II and  STX II 7.1 cards. It does work for the other UNi Xonar supported cards too. Replacement for 1.75b driver. Includes STX II version 11.5 audio drivers (built date: 18 Feb 2014, made by C-Media).

Driver changes:

  • Includes updated ASIO (2.0.0.14), driver installer, ASUS Audio Center and C-Media Panel.
  • Windows XP: Drivers now work for all UNi Xonar supported cards. These were not working with 1.75b drivers.

Other notes:

Rev. 2 changes:

  • Fixed “Asus Audio Center” not working properly and getting replaced by C-Media Panel when installing with “Normal – Asus Audio Center” configuration.

Rev. 3 changes:

  • Fixed some installation issues when drivers were installed on STXII cards (like missing driver uninstall entry in Programs and Features,  incorrect C-media panel name).
  • Fixed a bug where optimal card configuration was not being applied if the drivers were installed without the “Re-enable stereo upmix” option.

Possible issues:

  • Microphone stops working occasionally or when changing audio playback settings (DS->WASAPI). If you run into this issue please report it in a reply to this comment. If you frequently run into the issue you could try v1.75a drivers if possible or connect the microphone to the onboard audio card microphone input.

 

Release notes 1.75

UNi Xonar Installer changes:

  • Various changes and improvements done to the UNi Xonar installer.
  • Added warning message if installing the drivers would require Test Mode.
  • XonarSwitch is now automatically closed before installing the audio drivers.
  • Improved “Apply addons” function. Included .inf files from the drivers can now be dynamically altered. Documentation can be read here. Applying new 1.75 compatible versions of addons (like DHT4) will display the proper audio driver version now and users could now choose which addons they want to install once these are added to the Uni Xonar installer location.

Rev. 3 changes:

Driver for previously supported cards. Same audio drivers as those in 1.72 (1816 for Win XP, 1822 for Windows Vista/7/8/8.1/10).

Rev.2 changes:

  • Fixed ASUS and C-Media Panels not working in Win XP.
  • Includes updated driver installer and C-Media Panel.

Known issues:

  • The installer is showing “Warning: Test mode to be enabled!” message by mistake if Xonar Xense selected as card.

Possible issues:

  • Missing Dolby Pro-Logic IIx options from C-media Panel. If you have this issue, you can use the “C-media Panel v1.62” installer addon or install v1.72 drivers.
  • 1.75b “STXII”

Driver mainly for STX II and  STX II 7.1 cards. It also works with UNi Xonar previously supported cards.

Rev.2 changes:

  • Fixed issue where installer did not apply the correct audio settings (e.g. to fix surround echo). Anyone who installed the previous 1.75b drivers should install the 1.75b rev.2.

Driver changes:

  • Includes updated ASIO (2.0.0.13) , ASUS Audio Center and C-Media Panel.
  • Includes STX II version 11.5  audio drivers (created on 18 Feb 2014).

Other notes:

  • These drivers do not work for the other Xonar cards on Windows XP.

Known issues:

  • ASIO in 64 bit mode does not work. The cause of this issue is the 64 bit asio  dll file from the original STXII drivers.

Driver changes:

  • Updated audio driver to version 1822 for Windows Vista/7/8/8.1. Still using 1816 for Windows XP.

Release notes 1.71

Driver changes:

  • Updated audio driver to 1821 for Windows Vista/7/8  and 1816 for Windows XP.
  • Includes updated driver installer

UNi Xonar Installer changes:

  • Fixed some issues with Driver cleaning module
  • Improved and fixed some potential issues with UNi Xonar Installer

Known issues :

  • In some cases,  WASAPI exclusive playback is interrupted by playback from other audio applications. More details here.  Fix: If you don’t use S/PDIF, disable Digital Output from Control panel->Sound. It’s confirmed that the audio drivers included in 1.70 don’t have this issue.

Notes about Windows 10 compatibility (updated 25 Jan 2017)

UNi Xonar drivers above v1.64 will work in Windows 10 but since the audio drivers are not yet made specifically for Windows 10 there could be some issues that you could run into depending on audio settings used. Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions.

Apart from driver issues there could be issues solely from Windows 10 sound system that would be fixed with future Windows updates. There is also a small chance that some things could break with future Windows updates.

  • Update 30 Aug 2016: Thank you for the feedback so far. Based on the feedback received there shouldn’t be any problems installing the drivers on Windows 10 Anniversary Update (build 1607) whether it’s an upgrade or a new installation. One user reported that audio card was recognized only when installing the drivers when booting with Disable Driver Signature Enforcement option. Apart from drivers installation aspect, this new Windows build brings new problems for some users like the following reported ones: crackling or loud popping sound in the speakers, audio card not being detected sometimes or disappearing in Windows and 5.1 analog not working. For those of you who started having problems only after the Anniversary build upgrade you could roll back to a previous Windows 10 build (#1, #2). If that is not possible you can download a older Windows 10 build from here and install it without a internet connection present. To prevent upgrading to build 1607 you need to disable “Windows Update” service from Control Panel->Administrative Tools->Services.
  • Update 3 Aug 2016: Microsoft made changes to driver signature policy with the Windows 10 Anniversary Update (1607) that could make the Xonar drivers not working/installing anymore. There are some exceptions from this driver signature enforcement. At the moment it’s unclear to me if installing the drivers in Test Mode or with Disable Driver Signature Enforcement still works. I’m interested in hearing you experience under this discussion thread.
  • Update 28 Nov 2015: The Windows 10 Threshold 2 update does not seem to fix many of the sound issues that where present so far and it may introduce new ones. In my opinion Windows 10 is a very buggy OS, the only things working fine are the spying of its users(#1, #2) and the periodic removal of user preferences and programs(#1, #2, #3, #4).
  • Update 19 Oct 2015: The audio fixes from Insider Previews >= 10547 will probably be included in the upcoming “Threshold 2” update that will be released around November 2015.
  • Update 1 Oct 2015: The Windows 10 development team is fixing some audio issues with Windows 10. The fixes where made available for testing starting with Windows 10 Insider Preview build 10547.

100% compatible drivers when?

Because of the very slow development of the audio drivers by C-Media and the long time it takes for C-Media partners (ASUS and HTOmega) to release the new drivers it may take a while before we have a 100% compatible driver for Windows 10.  If we are lucky we will have new audio drivers in 2-3 months after Windows 10 RTM launch. As soon as new audio drivers became available I will release a new UNi Xonar drivers package.

  • Update 25 Jan 2017: 1825 audio drivers for Windows 10 are available. These are the first audio drivers that only work on Windows 10. Hopefully they will perform better than those that supported also Windows 7 and Windows 8.1.
  • Update 01 Oct 2015: 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.

About Chrome stutter issues on sites like YouTube. (27 Aug 2015)

  • Update 27 Aug 2015: The stutter issues on youtube are  fixed with the latest Chrome build released on 20 Aug 2015 (v 44.0.2403.157). Reports indicate that stutter issues are still happening for videos on other websites (eg. daily motion, facebook, instagram).
  • Update 7 Aug 2015: After some testing and some reading it seems that the stuttering issues are not related to the UNi Xonar drivers. I’ve got the same behavior with Realtek’s onboard audio and from what it looked liked. My guess the issue is caused either by Windows 10 or Chrome.

There is a Chromium issue opened here.

Here are some things you could try:

  • Change Chrome audio buffer size.
  • Change/keep sample rate to 44.1 kHz both in the audio panel and Windows Volume->Playback devices->(…) Audio Device Proprieties -> Advanced -> Default Format.
  • Change sample rates back and forward a couple of times.

    Hey, where are the links where i can download the drivers? The official drivers won’t work with my headset, saw an other post about this on an other website because the driver seems kinda buggy.

    Hi,
    1) i’ve just installed the last UNi Xonar W10 1825 v1.81a rev.2 drivers for my STX II sound card, when i play (first) foobar 2000 v1.3.10 in KS or WASAPI output and when i open and play just AFTER a video on youtube with chrome navigator, i have no sound in youtube and the video doesn’t start. is it normal ?

    2)When i launch for the first time xonar audio center from the start menu, it doesn’t launch, the second time, it’s ok.

    3) in Low DPC latency mode, C-media audio panel is impossible to pin to taskbar contrary to xonar audio center.

      Hi. 1) It depends. Do you have the same problem with previous drivers under the same circumstances? If yes then it’s not a driver specific issue. WASAPI output in foobar2000 is sound exclusive (no other sounds are played) so that might be what is causing the issue.
      2) Normal in “Low DPC Latency” and “C-media Panel” UNi Xonar configuration. First time you launch Asus Xonar Audio center it loads to tray. No way around this.
      3) C-media panel is not a .exe file so that’s why.

            Hi,
            About the issue at point 1, I tried UNi Xonar STXII 11.5 v1.80b r3 drivers, and when i play (first) foobar 2000 v1.3.10 in KS or WASAPI output and when i open and play just AFTER a video on youtube with chrome navigator, this time the videos start but without sound. With UNi Xonar W10 1825 v1.81a rev.2 drivers, the videos on youtube don’t start at all. It’s not a big difference 😉

            I tried UNi Xonar W10 1825 v1.81a rev.2 drivers with this time foobar in his last version 2000 v1.3.14 and this time, when i play (first) foobar 2000 v1.3.14 in WASAPI (event) output and when i open and play just AFTER a video on youtube with chrome navigator, the vidéo starts but without sound AND Foobar keep on playing the tune but without sound too.

      Is your card correctly detected by the UNi Xonar installer? Do other UNi xonar drivers work?
      Try “Possible solution 1” from this guide.

        i tried it and it got installed.. and then i choose 6 channels, six speakers and digital output 96 khz, but the sound comes from only two front speakers. I have tried all other combinations but the sound only comes from these two speakers. other three speakers remains idle..

        and i have to enable spdif output and choose PCM because i use audio opticle cable..plz provide a solution so that i would be able to play sound on all five speakers;.previously i have used your software and sound came through all speakers..i do not remember which version i used . but now i cant ..

          I’m not sure why you say you had all speakers playing previously.
          PCM SPDIF can carry only 2 audio channels. For 5.1 SPDIF output you need Dolby Digital Live or DTS Connect encoding and the DG you have doesn’t have those.
          More info about this here.

    I always used your driver for my Xonar DX, which is connected with the analogue outputs to my sound system. Never had any problem.

    However, using the latest version for my Xonar DSX machine, which is connected by SPDIF, does not let me enable DTS Connect, at least it is buggy. I am using the latest version of Windows 10 with all recent updates. Switching the SPDIF modes in CMedia or Asus center does not have an immediate effect on the input display of my receiver. With the latest Asus driver for the DSX it does switch between 2 or 5 channel input, when toggling DTS Interactive. When I run the Windows for digital output and DTS in the preferences, the receiver switches to 5 channels only while the test is running. After that, the card is outputting 2 channels again. And games do not switch to 5 channels. Asus driver works flawlessly.

    I installed the low latency solution. Any help is appreciated.

    Keep up the great work! 🙂

      I think this is one of those issues related to 1825 audio drivers for which there is no fix. Just to be sure that there was no installation error you should uninstall, restart and install the v1.81a drivers again.

    Hi all! It’s normal that when i use the LineIn and i surf with my browser the audio goes off and i need to go on record menu, disable linein monitoring, enable mic in and monitoring, disable mic monitoring, reactivate line in and click repeatly on monitoring linein to have the audio back?
    I’ve tried with UNi Xonar W10 1825 v1.81a r2 and UNi Xonar 1816/1823 v1.80a r3 and the problem is always that and it appears only when i open my browser and i surf on some internet pages.
    My audiocard is a Asus Xonar DGX.
    Thanks a lot for your help.

      Hi. Those web pages have audio playback?
      To rule out that it could be a specific driver issue you should try with 1.80b, 1.75a and 1.64 drivers.
      Don’t think I’ve seen someone else report such an issue. You’re running Windows 10 which has more issue with audio playback then previous versions. You’re also running a non standard audio setup. Things are complicated and I’m not sure there is something we can do about it.

      Hi,
      Have just been searching for a completely unrelated issue and have to mention I see a similar thing with the login page of Aliexpress.
      My setup is basic – just a pair of speakers plugged into the front/headphone input of a D2X, and when I first go to the login, I get the audible click from the sound card hardware itself that you’d normally get when it is initialising, when the machine is powering on. No issue with sound after that and there’s no repeat if I close the browser and try again straight away. Browser is latest firefox.
      Just thought I would mention it – I know that sometimes at least seeing that someone else has seen similar can help.

    Hi. I couldn’t find any info on this problem specifically, but I was wondering if anyone else had had this issue. On my current setup (Essence STX II, v1.80b, Windows 10 64-bit), whenever I adjust the volume in Windows it also adjusts the sound balance (so that sound gets pushed over to the right on my speaker setup); this is fine when using my speakers because I can leave the volume at 100% and adjust the speaker volume directly, but is a problem when using some headphones. I was wondering if anyone else had experienced this problem, or had any suggestions? Many thanks!

    There’s a slight bug I’ve found, which you may already be aware of. If so, sorry for the repeat. I searched to see if anyone else has reported this and didn’t find anything.

    Whenever XonarSwitch loads a profile, it always sets the microphone balance a few ticks to the right from center. I noticed this because I was doing the basic RMAA test of looping the sound card playback through the mic input, and there was more than a dB of difference in the L/R signals. Opening the UNi control panel and hitting the ^ re-centering button on the mic fixes the issue.

    The strange part is that the mic balance always gets moved back to the right a few ticks whenever the XonarSwitch profile is changed and even when XonarSwitch starts running after a system restart. Altering and saving the profile settings with live mode on to re-center the mic with the ^ button still gives the same bug when the profile is switched. I recorded some normal talking through my headset mic and confirmed that my voice was indeed panned slightly to the right when UNi control panel shows it as being a few ticks to the right, so it’s not just a GUI bug.

    Windows 7 x64, Asus Xonar Essence STX, UNi Xonar 1816/1823 v1.80a r3 (Low DPC Latency install), XonarSwitch 0.9.661. I’ve confirmed that the issue persists even after a full uninstall, driver cleaning, and reinstall (trying all three install options). The problem also persists with installing UNi Xonar 1816/1822 v1.75a r3. If you need any more information about my system or want me to try anything else to investigate further, let me know.

    Another quick query. I get the impression from your wording that v1.81 only supports Windows 10 because the C-Media 1825 driver itself only support Windows 10. So can we expect, moving forward, that all future C-Media driver updates (and consequently, UNi updates, I suppose) will drop support for older versions of Windows? I think I read somewhere that 1825 may fix the terrifying white noise scream of death that randomly happens. I’ve seen people mention that it’s been a bug ‘since Windows 8’, but I can verify that I have that very problem with Windows 7 myself. So it would be disappointing if the only way to fix it was to upgrade to W10.

    Thanks for your time and sorry for the long post. Not sure if this is the right place or if I should’ve posted this on the XonarSwitch page, as I’m not sure if the problem is rooted in XonarSwitch or the UNi driver itself, or even the C-Media driver.

      For the microphone imbalance bug. I’m 99% sure it’s a XonarSwitch bug. I will do some investigations on my part but you should already write a comment in the XonarSwitch page for this bug. Just so you know, I may unapprove that comment so that it will wait in moderation queue for when Giulio will resume work.

      Regarding the v1.81 query. 1825 audio drivers will only work in Windows 10. I don’t know what C-media plans are but I think chances for them releasing any new drivers for Windows 7 and Windows 8.1 are slim.
      If there are fixes that I can do on my end, I will continue to release new UNi Xonar drivers based on the current audio drivers for Windows XP, Windows 7 and Windows 8.1.

      Regarding the white noise scream of death bug. This might happen for different reasons on Windows 7 and Windows 8.1 than on Windows 10. So far I’ve haven’t seen reports that 1825 drivers fix this for Windows 10.
      I suggest you read the FAQ Q&A 18.

        Thanks for the quick response. I will copy my message over to the XonarSwitch page.

        I have read that FAQ pretty thoroughly. I get it almost exclusively when skipping around on Youtube videos, and almost always am listening through my speakers in that case, so the white scream of death is more of a minor annoyance than the heart attack inducer that it can be with headphones. Just really strange. I can’t remember where I saw people saying or speculating 1825 would fix it, so nevermind!

        Thanks again. Keep doin the lord’s work

    Hello, I’ve been experiencing huge fps drops on YouTube when watching videos in 60 fps on Firefox (51.0.1 on W7 x64 Ultimate). I’ve been able to pin down the cause to my Xonar DGX: without any driver installed the frame drops don’t happen, as soon as i install the drivers and the device is active the drops return. I’ve tried both Normal and C-Media configuration and previous drivers up to 1816/1822 v1.72 to no avail. Any idea?

        The big difference between me and ASUS is that ASUS took your money in exchange of a supposedly working product and it’s support. While I try my best to help people I have no obligation to fix ASUS issues and to support their cards. That being said, you are not welcomed here.

    For the STX II would be more suitable the UNi-Xonar-STXII-11.5-v1.80b-r3 instead latest ones?

    But also with these I noticed random crashes or sound missing on YouTube.

      You noticed random crashes or sound missing on YouTube with v1.81a or with v1.80b drivers?

      You should use the drivers that have less issues on your system.

    I’ve had this card (Xonar DGX) for about two years now, and sometime last year booted up to find a random background static sort of noise with random subtle beeps and tones. Strangely this noise is only ever in the left channel. After rebooting having turned the PSU power off for a few minutes, the issue had seemingly fixed itself. This happened once or twice a month at most, and every time it was after I had switched back to Windows from my Linux (Debian) dual boot. Note this background noise was present even when the volume setting was at 0%, 100% or completely muted, never present over PCM however. After messing around for a while I noticed that the pitch and sort of the consistency of this noise was linked to the activity of the GPU, while this sounds like EMI, I’m sure there’s more to it as at this stage it wasn’t permanent.

    However more recently, I reinstalled Windows 10 and decided to setup two of my HDDs in RAID 0 using my motherboard’s RAID controller. From what I can gather based on observing the boot process this is done by pre-loading some software the provides the RAID functionality. I’m sure that this is affecting the way the soundcard is being initialised in the same way that rebooting directly into Windows from my Linux dual boot used to.

    I don’t know if this immediately brings anything to mind, but I’m happy to try any suggestions people may have.

    Thanks 🙂

        I’ll try the front panel over the next day or so if I end up messing around with the card again. I usually connect my headphones to the rear headphone jack as the FAQ suggests.

        Something to note however, a few of my friends have this same card and I’ve borrowed one that hasn’t been used much and hasn’t been in use for maybe a year. This card is completely fine, no artifacts in the audio at all, while being attached to the original slot I used which is closer to the GPU. So I doubt this is just EMI, the sound is very consistently linked to GPU activity so much so that I can actually hear a regular repeated tone in the sound when playing films in VLC, probably when each frame is being pushed. One of my other friends had this issue also, after having a game crash and cause an audio loop. For him, reinstalling the drivers fixed the issue for some a while, but he’s mentioned having problems with it again since.

        The most likely conclusion being that my card is defective in some way. I’m still trying to work out how reinstalling the drivers or ‘leaving it for a while’ could fix a hardware defect. If I have any issues with the new card I’ll follow this up but for now it probably isn’t worth wasting any time on.

        Thanks for the quick reply.

        P.S. Some details that could be useful:
        – Soundcard: Xonar DGX
        – OS: Windows 10 (64-bit)
        – MB and CPU: Asus Maximus VII Hero with Intel i7 4790k
        – Driver: “UNi Xonar W10 1825 v1.81a r2” and previously “UNi Xonar 1816/1822 v1.75a r3”
        – Interfering GPU: NVIDIA GTX 780

      try this:
      turn up the volume hi enough that you can hear the buzzing from your speakers easily
      then ,take you side cover off of you case
      get a long (optional) screwdriver and loosen the screws(slowly)on the L bracket on your sound card
      list for a change in the sound level or frequency to see if it goes away
      if it changes or goes away ,it’s a ground loop caused by your case

      I had that problem and wound up changing .Power Supply,videocard,cables,receiver
      turns out ,it was the PC case

    Hi, I just upgraded to the STX II, and strangely, the v1.80a r3 flavor installs (Low DPC Latency option) and runs perfectly without being in Test Mode/“Disable Driver Signature Enforcement”. Furthermore, v1.80b r3 will not install properly, though I haven’t tried Test Mode/“Disable Driver Signature Enforcement”. The uNI installer says that I failed to click “Install” on a pop-up dialog, which I think is flashing on the screen for a split-second but disappears before I can click it, right before it attempts unsuccessfully to install the alternate driver. In Device Manager, it says: “The name is already in use as either a service name or a service display name.” Neither of the possible solutions for driver installation failure work either for v1.80b r3.

    I guess it’s not a problem since v1.80a r3 is working fine for me…? Is there even a potential difference in the sound between the two versions, or is it more of just a clerical matter with Windows and driver files/procedures? It’s strange to me because it’s the reverse of the behavior you state in the release notes.

    Another question… Is there any performance difference, as far as the Windows audio stack is concerned, when the playback and recording devices are set to the same format versus being set to different formats. I.e., if I’m using 24-bit, 44,100Hz playback, would matching that for my microphone be better for the Windows audio stack so that it is dealing with only one format; or, would using non-matching 16-bit, 44,100Hz for my microphone be better performance, since the lower quality format is less demanding? I guess it boils down to how independently the Windows audio stack handles playback and recording. If they are entirely separate processes, similar to how DACs and ADCs handle input and output completely independent, then I would expect the second case to be true.

    One last question, do you know of a way to disable/enable recording devices automatically when you switch profiles in XonarSwitch? I’m looking for it and can’t find anything, but I may just be stupid. I know you can mute the volume when switching but I’m looking to disable/enable my mic like you would do in the Windows sound control panel. Thanks for all your wonderful work and help!

    System info: Windows 7 x64, XonarSwitch 0.9.661

      1) Do you still have the old STX card in the same system?
      Is your STXII card properly detected as a STXII card in the UNi Xonar installer?
      Just to be sure, check the device id against this one: PCI\VEN_13F6&DEV_8788&SUBSYS_85F41043
      To do so, go into Device Manager, show the properties page of the device, go to the “Details” tab, and select the property “Hardware IDs”.

      That popup with install, it does automatically select Install so that’s not the issue.

      There are Windows 7 installs that have “Disable Driver Signature Enforcement” always running. Not sure what triggers that.
      There are also situations when a particular driver refuses to install even if that version was previously installed, this happened to me on Windows 10 and v1.80a drivers. Don’t know a fix for this situation.

      Speaking of audio quality between 1.80a and 1.80b, here you have the RMAA reports between v1.80a and v1.80b. I don’t think there is a distinguishable difference.

      2) I think it does not matter if the microphone is set to a different bit depth and I also think that setting it to 24 bit has a negligible effect on CPU performance.

      3) Don’t think there is such an option or possibility.

        I still have my old STX card, but not in the system of course. I broke it by pulling a copper trace when desoldering a SMD component, but I thought of a way to fix it today.
        But yes, UNi installer properly detected it as STXII and the hardware ID matches the one you provided.
        The only noticeable difference I see in the RMAA report is that v1.80a has a slightly sharper low-pass roll-off, but it doesn’t matter either way really because I can’t hear above ~18kHz.
        If the RMAA reports are just from looping the output through the line in, then they are of somewhat limited use for evaluating the output, because the line-in components aren’t as high grade as the output components. The isolated output should instead be compared versus a high-quality reference.
        Thanks for the other answers. It sounds like I should be fine with v1.80a on the STX II and I should just ignore that the installer compatibility was reverse of the typical behavior.

    Hey there,

    I’m using an xonar xense soundcard. I always used to be able to use MIC BOOST, but the option has disappeared after I made the jump from win 8.1 to win10.
    The option however is there for the “front mic” option.

    I’m currently using the UNi Xonar 1822 v1.75a r3 drivers, I’ve also tried their old official Xense_8_12_8_1795_Win8 drivers and your UNi Xonar W10 1825 v1.81a rev.2. The boost option on regular mic is complete gone.

    Any clue as to what I could do to try and get it back the way it was?

    Hi
    I have asus xonar DS (PCI) and I’am having hard times to make it work with my creative 5.1 speakers (analog). I get no sound from rear and center/woofer speakers.
    My set:
    windows 7 32-bit
    Mainboard ga8i865gme 775 rh

    Even during sound test. I tried almost everything :
    Disabled sound on mainboard
    Reinstalling drivers (original and Unixonar – different versions)
    Playing around with changing number of channels, ratio, sound effect (when i choos sound effect I hear rear and center sound test only in front left and front right simultaneously)
    Checked speakers – they work properly with sound blaster live card that I have (PCI).
    Checked od Linux system (Ubuntu) with alsa – same result
    Tried to disable DTS totally in playback devices – no result
    Changed PCI slot
    Checked the presence of voltages on board 3.3, 12, -12, 5 – all present on PCI and card
    Checked hardware on soundcard (partially) : caps ok, output mosfets ok

    Am I missing something? Is this card actually suppose to play analog output or not (obsolete outputs?) because it is hard to find anything about this card on internet (detail information about outputs, schematics etc). There is a manual which shows how to connect speakers to play analog 5.1 so I’m guessing it should work by design with analog speakers…
    Is it normal that spdif light is constantly being lit even if I am not using this output (it turns on instantly during boot)? Is it possible that PCI 2.2 is so essential that my Mainboard is not compatible (probably it has 2.1 PCI slots)? What other thing could go wrong in hardware or software?

    Thanks in advance for any help, materials, schematics. I’m running out of ideas. (Maybe connecting it offline and change settings of DAC register would fix this?)

      My guess is that you have a defective card.
      SPDIF light always being on is normal, kind of a bug on Windows Vista and newer but all cards do that.
