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’s 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.

 

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:

  • Fixed GX is not being turned off by default in Normal configuration for the following cards Xonar D2, D2X, DG, DGX, DG SI.

The 1.75 drivers come in two variants:

  • 1.75a “Standard”

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 will work with the previously supported Xonar cards on Win Vista/7/8.1/10 but may require that you enable Windows Test Mode on 64 bit OS.
  • 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.
  • Includes updated driver installer, ASUS Audio Center and C-Media Panel.

Other notes:

  • New icon for UNi Xonar installer. Thanks to propheticus for his contribution.
  • ASUS Audio Center and C-Media Panel tray icons now have higher resolution icons. Useful for >100% DPI settings.

Known issues:

  • GX is not being turned off by default in Normal configuration for the following cards Xonar D2, D2X, DG, DGX, DG SI.

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 :

Notes about Windows 10 compatibility (updated 10 May 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 20 Apr 2017, 10 May 2017: Windows 10 Creators Update (build 1703) reported issues so far are:

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 (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.

    Hello. Does anyone else have fun with the sound card driver if you use teamspeak? That is, the microphone is completely shut down for something. With 1.75 driver good but above they are not good either 🙁 (d2x)

    I found a particularly weird issue today, fresh W10 Pro X64 install, latest version for my D2PM ( 1825 v1.81a r2 ) and when I click on this button :

    http://imgur.com/a/EOTmf

    The music im listening to stutters for 1-2 seconds ( 100% repro rate ), to make it more weird, it only occurs on that specific button, no idea why.

    I was listening to music in my browser ( Chrome on mixcloud.com )

    Apologies – I’ve searched back a few pages but find no real easy way to search.
    Indeed, as many here, thanks for keeping this chipset alive as best as you can with what you’re given.
    I wish to report a BSOD that I can replicate almost 100% of the time.
    2 Windows machines, both Win10 Pro x64 – BSOD occurs both pre and post anniversary update (unsure if I have the Creative update yet, and I’m not in front of the two PCs as I’m making this report).
    Both were updated from Win7 x64 Ultimate. I don’t remember, but don’t think BSOD’s occurred pre Win10.
    Since June 2016 Win7=>Win10 update, both have been wiped and installed win10 fresh.
    Main rig – Asus MVN98TD Evo motherboard, Razer AC-1 Barracuda sound card. Have had 2 different AMD processors, and two diff chipset vid cards (Nvidia and AMD), so pretty sure that isn’t a factor.
    Secondary – An intel rig/no dedicated vid/sound, all on CPU and motherboard.
    I frequently RDP from main rig to secondary.
    If I leave RDP session connected. put main rig to sleep. Upon attempting to wake main rig, I almost always get “:( IRQL NOT LESS THAN EQUAL “cmudaxp/cmudxp/cmudexp?(sorry, I forget exact)”.sys – you can restart” bsod error.
    If I (remember and) disconnect the RDP session before placing rig to sleep, no issue with wake.
    Both with UNi Xonar W10 1825 v1.81a r2 (Cmedia no GX) and with UNi Xonar 1816/1823 v1.80a r3 (Cmedia no GX)

      Things you could try:
      1) You could try older drivers like v1.64.
      2) On Remote Desktop Connection settings you could disable the remote audio playback/recording if it’s enabled and you don’t need it.
      3) Try another remote desktop application like TeamViewer for example.

    I’m not sure if it’s my new Xonar DSX sound card or some other hardware failure, but ever since having mounted it I have noticed some random audio lag/freeze every once in a while and it completely freeze everything on my screen for a short duration ~1s at the most ever hour or so and it’s getting really annoying, especially when driving, would be kind of cool to see what’s making my computer react like this and I guess DPC Latency Checker would be a good starting point to see what’s up: DPC Latency Checker http://www.thesycon.de/eng/latency_check.shtml P8P67 DELUXE, i7-2600K, 16GB, GTX 760, 850 EVO on Windows 10 Pro (x64) Creators Update (1703/15063.250).

      DPC Latency Checker does not work correctly on Windows 10. Use LatencyMon instead. I suggest you install the UNi Xonar drivers with Low DPC Latency configuration and also try different drivers.
      You should remove the Xonar card and see if the issue is related to the Xonar card. The issue could be related to a failing HDD or some newly introduced issue with Creators Update.

        Thanks for the heads-up, I will try that.

        I tried running both v1.80a-r3 and v1.81a-r2 with the low dpc latency configuration, but the occasional audio freeze still occurs no matter what.

    Hello! Deleted v1.75a-r3, installed v1.81a-r2. It seems to work properly, but immediately there is a note – “ASUSAUDIOCENTER: Error” pops up on the test of the speakers, and the sound does not play.

    Windows 10.0.15063.250-x64, Xonar DS.

    Hi, I add my quick feedback here on the Unified love of Win 10. I had to go from Win7 to Win10 (creative update/1703) for a new Ryzen machine, and I installed again the Unified drivers for my Xonar DX (thanks for your work btw). But on the first reboot post install with v1.80a r3 (low dpc flavor), Win10 wouldn’t boot at all, black screen. I had to remove 1.80 and install v1.81a-r2 (low dpc flavor too) which was fine first reboot.
    Too bad I have no useful error message or log entry to share.

      Hi. Thanks for the feedback. How did you remove the v1.80a?

        I think the corresponding mode in english is: boot win10 in “failsafe mode” then uninstall Unified drivers like any other program.

      I’ve check this and I could not reproduce the issue on my system. Windows 10 CU with and without updates. Maybe that it was one time thing or it happens randomly.

    Ever since I updated to Windows 10 Creators Update, my Xonar DGX starts outputting white noise through right speaker after having my headphones unplugged for a while. The noise does not go away if I touch any setting other than changing the Analog output from Rear Headphones to Rear 2 Speakers from XonarSwitch settings, that or completely restarting the system.

      Which driver version have you installed? Have you tried with other driver versions? You connect the headphones to the front panel?

    There was a recent windows 10 update and since then, the sound card cannot or poorly plays audio bytes that are a fraction of a second long. For example, the sound a folder makes when you click on it is broken and so are hitsounds in overwatch, ect. I was wondering if there is a way to fix these issues with either a patch or if there was something else.

      I don’t think there is something I can do. You can uninstall the update and block it from installing again with Wushowhide tool. If you find the name of the update responsible please let us know. Once you know which update is responsible I suggest you report the issue to Microsoft.

    Thanks maxedtech! Out of blue I started having continuous background hiss (irrespective of audio playback ON or OFF. OS Win7 64) on my Asus Xonar D2X with official drivers. The Uni driver (UNi-Xonar-1823-v1.80a-r3.exe ) solved this issue incl. stuttering of audio if I did vol. boost in mixer->playback settings. Middle finger to Asus team.

    My Xonar DSX died, didn’t even last a month, all audio went bad (sounded like a loud bell in the win environment) then it all went, oh well, was happy while it lasted, cheers.

    After the upgrade to Win10, build 15063.296 the already installed UNi Xonar Driver 1825 v1.81a r2 is being blocked because it is unsigned. Re-installing with Disabled Driver Signature Verification works fine, but the freshly installed driver is blocked immediately after restarting the PC. So it doesn’t work anymore. Is there anyone who knows a solution?

      Which audio card do you have?
      On the same 15063.296 build, I’ve checked with the 1.80b drivers which are unsigned for my card and for me drivers still worked after restart. Might be a bug with Disabled Driver Signature Enforcement on your installation.
      You could turn on Test Mode or install the drivers that are signed for your card.

        My audio card is an ASUS Essence STX II. The problem is not the installation of the driver. No problem in test mode or with driver signing enforcement turned off. But when I shut down the PC and restart it after a couple of minutes Windows blocks the driver. Even with driver signing enforcement turned off permanently. On my second PC with the same audio card and Windows version the problem exists also – however it started a few weeks later. Can be a Microsoft policy…

          You might not understood correctly what I said. For me drivers that required “Disable driver signature enforcement” to install continued to work after system restart.
          When the driver is blocked, go to Device Manager and go to STXII card proprieties. What does it say under “Device status”?
          You should look into Windows’s Event Viewer->Windows Logs->System for the entry where Windows blocks the driver and tell me what it says.
          If you try the v1.80b, is this behavior happening?

          If we can’t figure out what’s going on, I might have another solution that could work, but it takes some time to do it.

            Drivers 1.80b r3 (signed) worked fine. But after upgrading to build 15063.413 driver version 1.81a r2 is working again (no longer being blocked). So indeed it seems like a bug in the previous Windows build (or in my installation).

    If you have an AMD video card, you should disable the HDMI audio if you have external speakers, and that should fix the popping issues on Windows 10. Just go to Device Manager and right-click the AMD High Definition Audio Device and choose Disable. Windows will ask you to confirm it. Say yes and exit out of Device Manager. I didn’t even have to reboot

    Anyone knows anything about the Xonar AE? Any plans to support it? There’s like nothing about it anywhere.

      It uses a C-Media USB2.0 6632AE audio chipset which is a different one than previous Xonar cards use so for that reason it can’t be supported with UNi Xonar drivers. This chipset is similar with that of ASUS Strix cards, I am not sure why they didn’t use that brand instead. From a quick look at it specs I would say it’s a card somewhere between Xonar DSX and Xonar DX in terms of sound quality.

        Yeah to me this looks like a modern Xonar DG basically with improved sound quality, official Windows 10 support and native PCIe (or atleast no PCI to PCIe conversion going on) hence why I’m also intrested in it now that I got a motherboard with no legacy PCI slots and can’t use my Xonar DG anymore. This is has been probably released quite recently seeing how little information there is about it. Hopefully someone posts a proper review soonish and what I’m most intrested in is if this has lower output impedance than what the DG(X) has.
