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 (, 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.

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

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.

    Hey, any chance of getting these working with Xonar U7? The standard Asus software is absolutely terrible…


  2. Walter Peck    17 Sep 2013 @ 00:30   

    Thanks both. I had tried XonarSwitch only the other day but it didn’t support Flexbass. I’ve just taken another peek and it’s been updated so I’ve moved to this.

    Thanks again.


  3. Kyrah Abattoir (@KyrahAbattoir)    17 Sep 2013 @ 04:16   

    Hey, first thanks a lot for those drivers, it’s so much better than the fficial asus driver.
    I was wondering if anyone could tell me what my problem is, when recording from the mic input of my xonard D1, i get a constant 10hz “tapping” noise that sounds a bit like a helicopter (but not very loud), it happen even when no microphone is actually plugged in the card.
    I removed the card, cleaned it (and the pci port) and reseated it and the tapping appeared to have vanished, but it came back during a skype call a few minutes later.
    Should i get a new card? Is this a common problem?


    • CarvedInside    17 Sep 2013 @ 23:35   

      I haven’t heard of anyone having this issue. have you had this before with asus drivers? The noise could be from the card or something else. My advice is first try with different version of the drivers, try 1.64 if you’ve used have 1.71 now. If issue still persists if it’s possible for you to try your card in another PC . If not try installing a temporary windows with Skype and required drivers only, use different drivers and see if you still get the issue. Let us know of any developments.


  4. Iksch    17 Sep 2013 @ 17:03   

    On Windows 8.1 Pro and Xonar D1 the C-Media Panel looks totally different, the card seems to get picked up as “Oxygen HD Front/Rear” and the mixer tab is completely non-functional.


    • CarvedInside    17 Sep 2013 @ 23:46   

      From feedback so far, C-Media Panel works with Windows2012R2 which is the server equivalent of Win8.1. Try uninstalling and installing again. Try a different version. Try installing without any addons if you are currently loading any.


      • Iksch    18 Sep 2013 @ 13:02   

        I didn’t use any addons, I tried the different install options (Low DPC and C-Media Panel) and reinstalling.
        Made some screenshots with descriptions to illustrate the issue here: is what it looks like on Win8.1 and is what it should look like. The Asus Panel works fine. Thanks 🙂


        • CarvedInside    18 Sep 2013 @ 20:40   

          I see. thanks for the details and for bringing this up. It seems it loads the XP version of the C-media Panel. I will have to see if there is something that I can do, if not only a new version of the C-Media Panel will fix this. Either way I think it will take some time to fix this. In the meantime you might be interested in XonarSwitch application that might fill the void. 🙂


          • Iksch    18 Sep 2013 @ 20:46   

            Thanks! XonarSwitch seems to work great! 🙂
            I’ll have to hold up on 8.1 anyway because Nvidia can’t release a driver for my 560Ti that doesn’t freeze – but that’s another story…

            Thanks for looking into it. Your driver package makes the card worth using.

      I’m having exactly same issue

    On the next release, can you make it so HSMGR64.exe and HSMGR.exe are optional start up e.g start as disabled due to some games (Saints Row 4) failing to launch because of it. Only just fount the fix, after someone on the steam forums mentioned that this kills it!


    • CarvedInside    17 Sep 2013 @ 23:26   

      You can use Low DPC Latency configuration when installing and manually add Xonar Audio Center to Startup. This will get you basically what you want without HSMGR files. Now I should mention that usually hsmgr exes do not do much without enabling GX option in Xonar Audio Center. Just for my information, have you enabled GX or not?


      • David Lykaios    17 Sep 2013 @ 23:38   

        I havent got GX enabled, but the files still load up by default because its added as a startup item.


        • CarvedInside    18 Sep 2013 @ 20:33   

          I see. Thanks. That’s the default behavior for them to autostart.
          Next time follow my previous instructions and you will be set to go.

    It’s intersting to see the battles of opinions between driver quality Asus vs (new) Creative in users mind…

    Read the comments at the bottom…Unixonar is brought up in discussion too..

    Does anyone have a clue why my Microphone Boost option gets disabled after restart. It wasn’t like this before, but after my latest Windows installation it started happening.
    I’ve reinstalled the drivers numerous times, but still after every restart microphone boost is disabled.

    It is very annoying.


    • CarvedInside    20 Sep 2013 @ 17:44   

      Could be a application that runs at startup and changes the mic behavior. For example Steam has mic options and can override the default one. You need to enable the mic boost in settings for that respective application.

    Hi, I am running WIndows 8.1 official RTM (from MSDN) atm, have a Xonar DX and can confirm that the 1.71 drivers work fine. I will continue to check functionality and if bugs occur I will post them.

    Hello, i am really happy that someone is out there to solve our problems. i have one small request . for first time users like me i am having a tough time adding the standalone packs could you please help me in making a tutorial with all the steps in detail. your help will be gladly appreciated. Thank you. I own a xonar DG card.

    LE: Sorry i just found out . i had to rename the file to .zip. i request someone to post the correct settings for using the sound card. EX: which feature should be enabled which should be disabled. i have connected my xonar dg sound card to logitech x540 5.1 speakers. running win 7 x64.


    • CarvedInside    20 Sep 2013 @ 20:59   

      The standalone pack is a self extracting archive, don’t know why you would have a problem with it.
      Now you need it this only if you want to change specific things and not go to the Asus panel.
      You can read recommended settings for the card in the FAQ: Q&A9.

    I’ve got a new D1 that I’ve set up in a Win 7 64-bit workstation but the 5.1 output is really erratic with the Asus and UNi drivers – when I use the test app and keep clicking on the a specific speaker (i.e., Left Front) about 1/5 of the time, the voice comes out a different speaker than expected. Any ideas what might be wrong?


  11. David Chramcow    24 Sep 2013 @ 07:15   

    I actually have an issue to report under Windows 8.1 Pro RTM.

    I recently purchased an AMD Radeon HD 7970 GHz Edition Vapor-X video card, after installing it I thought it would be a good idea to re-install Windows from scratch and seeing how Windows 8.1 was just made available through Microsoft DreamSpark I went ahead and installed it. To my surprise, the latest UNi Xonar Drivers (1.71) didn’t work under Windows 8.1, it made my Xonar DS completely non-functional, it wouldn’t show up under Control Panel/Sound, etc, I had absolutely no audio from it, it did show up under Device Manager with an exclamation point, meaning that something had gone wrong in the installation. Under Device Status it said:

    “The device cannot find enough free resources that it can use (Code 12).

    If you want to use this device, you will need to disable one of the other devices in the system”

    So after a couple of hours of testing (I actually removed the card and put it in another system and it worked flawlessly), I made the decision to rollback to Windows 8, after the install, everything was working perfectly, just as it should. Are these drivers not ready for 8.1?

    Couple of notes:

    * I did disable Driver Signature Enforcement Policy prior to the install under Windows 8.1
    * Under Windows 8.1 Preview, everything was working perfectly, so there’s gotta be something different in the RTM build.

    Thanks and please reply back.


    • CarvedInside    24 Sep 2013 @ 17:42   

      I personally didn’t had time to install Win8.1 and test the drivers, but reports from others said that drivers actually work in 8.1. The only issues where C-Media Panel doesn’t show the options properly and there might be some issues with WASAPI playback. Now in your case I don’t know why they didn’t work at all. Seems like a resource conflict with other devices. Don’t really have a solution for you now.
      It could be from the audio drivers, these pre-8.1 drivers in particular cases not working properly or it could be something else like other drivers or a bug in Windows 8.1 RTM . Anyway we will know more once C-Media releases audio drivers specifically for Win 8.1 (so far there is no sign of them) which I will use in a new release.


    • MasterFaster    24 Sep 2013 @ 17:45   

      Have you tried to disable the on-board audio?


  12. David Chramcow    24 Sep 2013 @ 18:42   

    Thanks for the replying you guys.

    Yeah I really don’t know what was causing that issue, I did remove the onboard audio (it’s been disabled since day one). It’s a damn shame since I was really liking Windows 8.1 lol, but I guess I’ll have to wait for the new C-Media drivers.

    One more thing, this issue was present in not just one Windows 8.1 install, I reinstalled 8.1 (fresh install) around 3 times, and every single time the card failed to install correctly.

    Xonar D2, XP pro, Tritton surround sound Headphones.

    I know many people are using Windows 7/8 now but I am still using XP Pro (Don’t hold it against me)

    Thanks for your hard work in modified drivers. I have a problem getting the speaker test to work on v1.70 and v1.71. When pressing the test button it sticks on “Left Front” The setting are Sample rate:192khz. Analog out:5.1 speakers SPDIF Out is unchecked, all others unchecked. When I could not get the speaker test to work I just clean uninstalled that version. V1.64 works no problem and the surround test works, so I am still using this version.

    I see audio drivers have been updated
    v1.71, 1816 for Windows XP.
    v1.70, 1814 for Windows XP
    Could the updated audio drivers be the problem that I cannot get these versions to work?.


    • Exactmat    08 Oct 2013 @ 17:14   

      I’ve the same problem but i only use Analog 5.1 and headphones.


    • CarvedInside    08 Oct 2013 @ 18:16   

      Yes these new drivers could be the problem. Does the 5.1 sound work properly in a game or movie? Because if so it could be a bug limited to the speaker test within the 1.70 panel (ASUS Xonar or C-Media). Btw, which panel did you use?
      You are perfectly fine with 1.64 drivers, the audio drivers included in UNi Xonar 1.64 may in fact be the best drivers until now.

      FYI, since you’ve mentioned you have set sample rate to 192KHz, maybe you may want to have a look at FAQ:Q&A9.

    Is they any news if Asus Xonar D2X will support Windows 8.1? I have this card coming tomorrow I using Windows 8 atm but I now worried this wont work under 8.1 🙁



    • David Chramcow    07 Oct 2013 @ 21:59   

      Well in the 8.1 Preview Version the UNi Xonar drivers installed perfectly for me, but maybe something changed in the RTM build that made the install unsuccessful, I’m really hoping for an updated version for 8.1.


    • CarvedInside    08 Oct 2013 @ 18:27   

      There is a note in the post above about Windows 8.1 compatibility. It could work fine.
