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.

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. RightMarkAudio tests that I’ve made didn’t show any significant differences between v1.81a and v1.80a.
  • The 1825 audio driver may have higher DPC latency than previous drivers. Original report. The tests that I’ve made didn’t show any difference in DPC Latency between v1.81a, v1.80a and v1.80b drivers. Maybe it has to do with the settings that are being used.  My test where done with 2.0 analog output.

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.
  • Windows 10 Creators Update: Windows would not boot after these drivers where installed. If you run into this problem you have to boot Windows in Safe Mode and remove the audio drivers. Original report. I could not reproduce the issue.
  • 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.

Notes about Windows 10 compatibility (updated 13 May 2018)

UNi Xonar drivers v1.64 and above will work with 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.

Windows 10 (multiple versions) possible issues and fixes:
  • Microphone not working – Check this guide. (thanks Shane)
  • Audio crashes – If you have “Dolby Atmos for Headphone” app installed you should remove it and replace it with the updated “Dolby Access” app in order to avoid audiosvr process stack overflow errors that are crashing the audio subsystem. (thanks Chris Leipold)
  • Popping and cracking sounds – If you have a AMD graphics card, try disabling AMD High Definition Audio Device from Device Manager. Possible to try the same steps for Nvidia HD Audio Device for Nvidia cards. (thanks Marc)
  • BSOD’s after system wakeup from sleep – Try UNi Xonar v1.71.1 driver. (thanks Kalle)
Windows 10 version 1803 (April 2018 Update) notes (updated 13 May 2018)

Our community member Chris Leipold reports that the wake up from sleep BSOD, settings reset and not working audio server process at startup issues that where introduced with Fall Creators Update are fixed with Red Stone 4 preview (pre 1803 release).

Possible issues and fixes:

  • Microphone not working – Check this guide. (thanks Shane)
  • Audio crashes – If you have “Dolby Atmos for Headphone” app installed you should remove it and replace it with the updated “Dolby Access” app in order to avoid audiosvr process stack overflow errors that are crashing the audio subsystem. (thanks Chris Leipold)

Possible issues reported so far:

  • Settings (Bit-depth, sample rate, number of channels) reset bug when clicking the volume after restart might still happen (#1)
  • Windows might freeze when installing Xonar drivers (#1)
  • Microphone might not work even after doing the microsoft privacy toggle fix (#1)
  • S/DPIF output might not work at least for some with Xonar DG cards (#1)
Windows 10 version 1709 (Fall Creators Update) notes (updated 13 May 2018)

Reported issues so far:

  • Drivers above 1821 v1.71 may cause BSOD when waking system from sleep (#1, #2, #3). It’s unclear if it is a driver issue or a Windows issue that’s triggered in specific conditions that are met when using drivers above 1821 v1.71. Since ASUS/C-media driver support is pretty much dead and most people didn’t have this issue until Windows 10 Fall Creators Update, people having this issue should contact Microsoft support and submit their crash dumps.
  • Card settings are being restored after each restart. A temporarily workaround would be to save your settings as a XonarSwitch profile and apply it each reboot. Anyone affected should report the issue to Microsoft. Update 6 Feb 2018: it looks like this is fixed in insider builds >= 17074, and it will be fixed in Windows 10 version 1803. Update 8 Mar 2018: this should be fixed with KB4074588 update for version 1709.
  • Default format (bit-depth and sample rate) from Windows Volume->Playback devices and the number of audio channels resets each time the Windows Volume icon is clicked (#1, #2). Anyone affected should report the issue to Microsoft. Update 8 Mar 2018: this should be fixed with KB4074588 update. Update 13 May 2018: This issue might still happen even after installing KB4074588 (#1).
  • Possible high frequency tone when playing audio.
Windows 10 version 1703 (Creators Update) notes (updated 10 May 2017)

Reported issues so far:

Your feedback is welcome.  For those of you who run into severe problems after the Creators Update build upgrade you could roll back to the previous Windows 10 build (#1, #2). If that is no longer possible you can download an older Windows 10 build from here and install it without a internet connection present.

To prevent Windows 10 upgrade to Creators Update you need to either disable “Windows Update” service from Control Panel->Administrative Tools->Services or disable the Creators Update update with Wushowhide tool (guide on how to use it).

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 (version 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.

    I’m so fed up with that Essence STX II.
    Switching from speakers to microphone might lead to an immediate system reboot.
    Using Rosetta Stone with headset might lead to an immediate system reboot.
    Opening a YouTube video or a movie might lead to an immediate system reboot.
    Configuring Mumble might lead to an immediate system reboot.
    It doesn’t matter if I use the official or unofficial drivers. It even behaves like this on Linux.
    The sound quality of the card is brilliant, but the headset should be used with an onboard solution. Then it works. Next time I’m going to buy a sound card, I’ll have to be more careful.

    I’m seeing an issue with application exclusive access and the C-media & GX enabled installation. “Normal – Asus Audio Center” installation properly manages exclusive access whereas it’s a free for all with “C-media Panel with GX enabled.” Reinstalling (and letting the device driver scrubber run) “Normal” corrects this situation.

    • CarvedInside08 May 2018 @ 18:59

      Please clarify this issue with application exclusive access. I don’t understand at what are you referring to. Don’t the drivers install with “C-media Panel with GX” or WASAPI exclusive mode playback does not work?
      Tell me your complete OS version and which UNi Xonar drivers have you used.

    Hello,
    After big update of Windows 10 (version 1803) at the beginning of May in my ASUS XONAG DG S/PDIF Optical Output doesn’t work at all. I tested many versions of drivers from this website but this problem still exist. Before Windows 10 BIG update this drivers works correct. Right know don’t know what to do because I have Low Profile Dell 9010 and not possible to buy other card with Optical output. Waiting for any tips.

    Microphone stopped working too even I checked this solution http://maxedtech.com/fix-microphone-not-working-in-windows-10-1803/

    I called today to Microsoft. They connected to my computer and told that they have many phone calls about not working microphone in new version of Win10 after big update. We have to wait for MS update. Last problem not solved … why I see jumping level of sound on SPDIF optical output but no sound on amplifier? Cable is correct.

    • VforVendetta12 May 2018 @ 18:14

      Did you check your data protection settings? There, I had to activate the microphone in order to use it. This window also allows you to grant Windows apps microphone access.

    Just want to report that on latest Windows 10 64bit 1803, build 17134.48 everything works perfectly fine with my Asus Xonar DSX using UNi Xonar W10 1825 v1.81a r2 driver package . DTS Interactive , DTS NEO , everything in games like Ghost Recon Wildlands and Far Cry 5 ..amazing audio quality so quite happy for now 🙂 ..a yes I could play DTS-HD and DTS-Master via KODI . Also for unexplained reason I can play Dolby Atmos from Netflix ..some shows / movies are designated 5.1 but some are designate Dolby ATMOS and it works I’m quite surprised. Any logical explanation ?

      As far as I know atmos is just a TrueHD soundtrack embedded with some spatial information. So it will be decoded normally as a multi channel soundtrack.

        Interesting , thank you! I’m more on DTS side and always was, didn’t bother much with Dolby , However NETFLIX use Dolby only so I was surprised to see that some shows/Movies play as “Dolby ATMOS” there is a difference between in audio quality and channel positioning between Atmos designated and the one only with 5,1 it is more dynamic and the sound appears all around while on 5.1 it is mainly… how should explain it ..focused… back and forth and it is also atmospheric but not in the way Atmos does . Good example was Alteret Carbon . I thought that ATMOS is a special kind of multi-channel stream that needs specific ATMOS designated equipment never though ti could be reproduced or maybe simulated by Xonar DSX .

          The DSX certainly doesn’t do any such things.
          Maybe the netflix client (or whatever you play them back with) has a proper decoder/dsp for Atmos. Apparently there’s even a free Dolby Access app that can render Atmos streams for headphones.

    Just wanted to add: Essence STX Upgraded to Win10 1803, no problems that I can see. Gaming continued as normal. I do have my microphone set using onboard, output sound through the normal STX headphone jacks. (my card’s microphone ports? or software? who knows. stopped functioning correctly a while ago.)

    Hello,

    I still want to add up about the reported issue “Default format (bit-depth and sample rate) from Windows Volume->Playback devices and the number of audio channels resets each time the Windows Volume icon is clicked (#1, #2). Anyone affected should report the issue to Microsoft. Update 8 Mar 2018: this should be fixed with KB4074588 update.”.

    It seems that it still rarely happens to reset itself (it only happens after restarting Windows on a rare occasion). However, when it comes to opening the volume mixer the first time after Windows has restarted, any program or game that is running before you do that will either try to reset its audio, no longer outputs audio until you restart or it will just straight up crash.

    This has been going on for a very long while and it has started to happen for me after the fall creators update and it still rarely happens after the KB4074588 update and that it still hasn’t completely fixed it (for me at least).
    Using STX II on v1.80b r3 and also running on Windows version 1709 (OS Build 16299.431).
    It’s possible I’m the only one that has this problem but I’m probably just going to assume that version 1709 still hasn’t completely fixed it.

      Also, to add up to it: I’ve just updated to Version 1803 (OS Build 17134.48) and the same issue still persists.

      What a mess Windows 10 is. It sounds like they didn’t fix it completely. You may want to contact MS and let them know.
      Thanks for the report, I will update the notes.

        They rebroke it with the latest update. It was fixed before (at least for me). Now if i right click the first time, it reset to default values.

            I had the February 13, 2018—KB4074588 (OS Build 16299.248) that fixed the issue.
            But the in the Windows 10, version 1803 it is broken again.

    Hallo, I just bought and installed my new ASUS Xonar Essence STX II on my HP PC (with Front Sound detection) running WIndows 10 Enterprise version 1709 (OS Build 16299,402).
    Only got sound from my left earphone and none on the right side.
    Today I also installed the included RCA splitter (red/white) on the card (useless I thought), but….. now I got sound from left and right

    • CarvedInside16 May 2018 @ 02:46

      If I understood correctly, when you’ve used the front panel connection to your STX II card it only worked for the left channel. If the front panel connection worked fine with the onboard card then the your STX II card has a faulty part in front panel output circuit. There is no software fix, only replacing your card.

      • bird4218 May 2018 @ 20:30

        The Front Panel connection on my HP-computer works flawlessly with the onboard sound-chip. When I disconnect the front-panel-connector from the motherboard and put it on top of the STX II, I get an error from my HP computer, something like 100….. front-panel connector is not connected. (I cannot disable the onboard chip in HP-BIOS).
        solution: I connected my earphones directly to the earphone connector on the STX II (via the 6.3mm connector), that gave me only sound on the left side of the earphone, but when I also plugged the RCA splitter on the card, I got sound on both sides of my earphone.

    It’s a big shame for ASUS corporation to release drivers for ASUS Xonar soundcard which are not correct working with Windows 10. Asus do not update this drivers a lot.

      While ASUS is at fault for not supporting their products in general regardless of Windows version. In this case I believe it’s Microsoft fault for most of the issues. Other sound cards are affected by these as well. They brake compatibility with devices, make systems not boot, destroy drive partitions or introduce other unthinkable problems with each new feature update where MS mostly changes something to the interface, updates Edge and adds some new gimmick feature. With Windows 10, even stable releases, you are the beta tester.

    1. Noises
    2. Distortions
    3. screech
    4. Low voice level
    Updating the driver did not help.Reinstall Windows did not help. Question: how to fix it?

    Oh, and I am not use ur drivers, because i reinstall windows and want check work sound card and microphone on standart drivers for Xonar ST (not STX) on win 10. But it’s fiasco, bro…*( Please, help me.

      Sorry, at the moment I don’t know what can be done.
      Have you tried some of the UNi Xonar drivers?
      Did you have this issue before or it suddenly appear, maybe after a Windows 10 version update or some other factor? Which Windows 10 version you have?

    Hi CarvedInside,

    I have a STX card. I downloaded the latest Windows 10 update (1803) and I’m having a really big issue with a looping sound bug. It doesn’t matter what feedback it receives, it just loops over and over. I have tried uninstalling and using different drivers, do you have any thoughts?

    Thank you

      Follow up: Roll-backed to the past version (it broke multiple programs, thanks Windows). Issue no longer persists

        Probably better. I don’t know what could be done about the looping sound issue.
        Seems like MS are really making an effort to drive people away from Windows.

          Cheers for the reply,

          Yeah it’s definitely a pain. It’s an issue I’ve seen discussed many times in other forums, but this symptom was always resolved by downloading your drivers, so that’s interesting. Looking back I think it was like an echo, just a feedback loop–as if you held a microphone to a speaker and set it on listen and it’d just repeat on and on.

          Cheers for the reply

            Honestly the whole blame should go to ASUS this LAZY FUCKS don,t do shit to keep their device driver’s updated for every single peace of hardware they are doing . They have quality hardware , YES ! but UTTER SHIT IDIOTS in drivers and support teams . They are the root cause for all the problems ..not MS .

              Both are. Drivers shouldn’t need updates when the interface hasn’t changed.

                Regardless, I’ve been so impressed and glad with the Uni support in the absence of either Asus or Microsoft. It feels like being trapped on hardware island with an expensive sound card that is losing the battle against time.

          if you are after DTS it is, both are 5.1 though so no gain here , with SB Z the future of driver development and support is guarantied although SB iz lazy as fuck to release new drivers but XonarDG is officially dead for ASUS and no upgrades whatsoever . I have SBZ and Xonar DSX and I prefer DSX over SBZ as long as it is functional . So I keep my SBZ as a backup card.
          SBZ is straight forward , no problems easy to install , sounds great with Dolby Digital Live or DTS Interactive if you are after encoded signal , Software is easy to understand and full of features .
          You can simultaneously play over OPT out using DTS Interactive and analog out without any problem.
          In case of DG Ill go with SBZ
          In case of DSX ill go with it as long as it is functional.
