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. 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.

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.

    Hi. Latest revision working OK(windows 10), except impossibility to play “demo-(test)” sound, to check if all my surround speakers are working normally. how to fix that? tnx


    • CarvedInside    05 Feb 2017 @ 16:56   

      Hi. The demo test in ASUS Audio Center or C-Media Panel? Which drivers did you had before installing v1.81a that had a working demo test sound? Your card is?


  2. Den    05 Feb 2017 @ 11:48   

    I also installed UNi Xonar Drivers v1.81a rev.2 (low DPC version) on a Xonar D1 (Windows 10 64-bit) and the sound has changed and has become incredibly deep crystal clear. It is a very, very good Drivers. Thank you.


    • CarvedInside    05 Feb 2017 @ 16:57   

      Thanks for the feedback. Which drivers you had previously?


      • Den    07 Feb 2017 @ 20:32   

        UNi Xonar Drivers v1.81a rev.1 (standart version)


        • CarvedInside    07 Feb 2017 @ 22:07   

          I meant previously to v1.81a.


          • Den    08 Feb 2017 @ 22:58   

            By the time the output drivers in order: v1.75 and v1.80 (in the default settings, no extra bells and whistles). The last driver with high class, the sound is very soft and detailed, I dissolve it.


            • Fey    11 Feb 2017 @ 14:43   

              I believe I can agree with Den, the sound signature has definitely changed with this new driver. I previously had UNi Xonar 1823 v1.80a.


              • Anonymous    13 Feb 2017 @ 22:45   

                I can also confirm that the sound is different between the “STXII 11.5 v1.80b r3” version and the latest generic one(W10 1825 v1.81a r2)


    • Nick    08 Feb 2017 @ 02:59   

      You probably had EQ active or had GX enabled (which I noticed distorts the sound in many cases.)


  3. Anarion    06 Feb 2017 @ 02:03   

    I installed 1.81 r1 Xonar D2/PM Windows 10 x64 and I think the audio is kinda different from 1.80. It may be a placebo but I think the audio is clearer now. It sounds a bit more “metallic” than before. Albeit clearer but it’s like it’s lost depth and volume. Volume is 100% on driver panel and Windows volume slider. Sample rate is 48khz on driver panel and Windows settings is set to 24bit 48khz. Same settings as with 1.80 which I had before.


  4. SaLaDiN    06 Feb 2017 @ 12:42   

    Hello, this might be a stupid question, but better safe than sorry :D.

    I am running Win7 64bit and Asus Xonar D2, so I guess, I should not download the 1.81a driver, right, is it purely only for W10? And if I want the latest one, I should go for the 1.80a “Standard”. Thanks for the help.

    Anyway, thank you for your hard work, you are doing a great job.

    Ooooh, and one more thing. Seeing known issues in 1.80a “Standard” about a mic turning off, I can confirm this with Discord.

    Discord is somehow turning off a mic completely or turning off a mic boost /but in the Asus Xonar app the boost is still marked as being turned on/ when you launch it. Restarting the system usually works, but it is like rolling the dice, once I was on a bad mic turning off streak, had to restart my pc 6 times in a row cos ASAP I launched Discord, a mic went off once again or the output from mic was so low, that friends could barely hear me.

    But found some possible fixes:

    1. When the output from a mic is unusually low, going into the Asus app and turning off/on a mic boost helps to restore the volume to the normal level.

    2. Turning on a mic on my headphones before starting the Discord app usually helps to prevent a mic going off completely to some degree and the issue occurs less often, not getting a warning from Discord that no input from my mic is detected so often.

    Hope this helps someone to cope with the said issues, cos restarting pc is annoying.

    Gonna test now the 1.75a “Standard” driver to see if the mic issues still occur.

      Hi. Yes, v1.81a is only for Windows 10. I’ve written about this in the release notes. v1.80a is the latest for Windows 7.
      About the microphone problems, let us know how it works with v1.75a.

    Hi CarvedInside!
    You and your drivers ROCK! I use your drivers with Razer Barracuda AC-1 sound card and it’s still better than 2016 Asus motherboard int. Supreme FX. I just wanted to ask does my card support Xear 3D, because if I activate that then I see no difference and I only know if I try to play Elder Scrolls Oblivion then game crashes if it’s activated. I don’t even know well what does Xear 3D do and If it’s even supported newer games and software?


    • CarvedInside    07 Feb 2017 @ 01:01   

      Hi. Xear 3D aka GX in Asus Audio Center is EAX emulatator. EAX is not supported in newer games. You can google for EAX supported games. I don’t recommend you use it(see FAQ Q&A11).

    Somehow the Line-In input sounds a lot softer with v1.81a rev.2.
    Have a PS4 connected to Line-In on my Xonar DX.

    “Added DPI interface scaling to the installer” ? Does this mean that the AsusAudioCenter will display correctly on UHD 4K monitors? I’m Ready to dump the Xonar DG because of the TINY ControlPanel – “AsusAudioCenter.exe”. I’m not displeased with the function or sound of this card with the stock drivers, and have been using this soundcard for years, Headphone and Spdif to Entertainment center. I actually have a new extra retail box one i liked it so much when i bought it. I tried a rReg Hack and .Manifest file (for photoshop) and it Did make the AsusAudioCenter.exe display large and readable for a short time, but i figured out that – that was removing the entire windows Network Tray Icon from Win 7!! Anyway do these drivers/fixes work on the problem with 4K monitors’ display of Asus control panel?? I would love to get this fixed, surely there’s a fix to the Exe or something without manifest files screwing up windows system. Help !?!


    • CarvedInside    07 Feb 2017 @ 15:17   

      The key word is installer. If I would have added DPI interface scaling to Asus Audio Center I would have said so.
      For your problem, you might want to try C-media Panel that is included in UNi Xonar drivers with Low DPC Latency or C-Media panel configuration. Or try the standalone XonarSwitch.
      If you want DPI scaling to Asus Audio Center then you should write to ASUS support. If we try, maybe we can come up with different hacks to make it work but they are the ones that could fix it.


    • CarvedInside    08 Feb 2017 @ 17:44   

      I’ve deleted your 2nd comment since it is insulting and inappropriate. You should know that you don’t mock and insult someone and then ask for their help. With this kind of behavior you are not welcomed here.


      • Gripsz    09 Feb 2017 @ 13:11   

        Please Forgive my Reply to your comments, it was totally inappropriate in this venue. I did as you suggested LowDPC version 1.71. Fixes DPI issue in that SysTray Icon is not preloaded, and when you Run AsusAudioCenter.exe from UniXonar Menu it loads to tray – then you can double click systray icon (once you set it to always show in tray) and DPI looks Great. Thank You Very Much. I tried Copying link to AsusAudioCenter to StartUp in Windows Start Menu but we’re back to tiny dialoged panel on that one. Could you tell me if there is a way to run, or a version of, this AsusAudioCenter.exe that will simply run and not Load into Systray – so i can simply run it from Windows Taskbar?

    Hi, I have a problem, I’ve installed UNi Xonar 1816/1823 v1.80a r3 for Win7 (low PDC) and now every time I adjust volume and audio starts to play I hear crackling noise out of speakers. Connected via SPDIF.


    • CarvedInside    08 Feb 2017 @ 17:33   

      Hi. Which drivers you had previously installed that worked fine?
      Try uninstalling and reinstalling the v1.80a drivers. If you still have the problem, try with v1.75a drivers.


      • Kein    08 Feb 2017 @ 17:42   

        None, I just got Xonar DG and installed anew,


        • CarvedInside    08 Feb 2017 @ 17:48   

          You should have mentioned that. Maybe your card is faulty and has nothing to do with the drivers. Try what I’ve said above. Check the analog outputs as well. Try your card in another PC.


          • Kein    08 Feb 2017 @ 17:52   

            Yeah.. thanks. Wish I had a luxury to check in “another PC”. Wanted to try to locate issue with what I have. At least it was somewhat cheap.


  9. Kein    08 Feb 2017 @ 19:55   

    Also, question: is there a way to have working headphone connected to FP while speakers connected via SPDIF out?


    • sxt2    09 Feb 2017 @ 11:53   

      DISABLE SVN, that causes the crackling on all the drivers.


      • Kein    09 Feb 2017 @ 19:25   

        Thanks but it never was enabled. I will probably just return the card and swap for Audigy, can’t really use it if can’t do SPDIF out + analog together. Not Mic, not Headphones work. Meh.

    work in new version driver(xonar D2, w7 x64) ASIO sound with other sound? For example, play music via asio and call of duty playing. This is for me big problem, because after stop play music other sound not work, or for another functionality ASIO is necessary to close the browser, etc. Patch ASIO 1.0 not work.

    This is why Xonar in the box and X-Fi Elite Pro in the PC


    • CarvedInside    14 Feb 2017 @ 00:46   

      The ASIO included in the Xonar drivers can’t do that. You could try a ASIO 4 ALL. In case you need other sounds to play as well I would suggest you use DirectSound or if possible the WASAPI (nonexclusive) output playback.


  11. maciejak    13 Feb 2017 @ 11:48   

    I install last driver 1.81 rev2 on win10 with Xonar Essence ST, but i hear sometimes clipping ? Latency asio is ok and volume is ok. What is problem ?


    • CarvedInside    14 Feb 2017 @ 00:40   

      You have this problem with ASIO playback? To confirm that this is a driver specific issue, you should try with previous drivers and again with 1.81.


      • maciejak    17 Feb 2017 @ 01:41   

        A both drivers 1.80 and a.1.81 have sometimes clipping. I update my Aimp to 4.13 and the same problem, maybe not big problem, but make me angry. Why it is that clipping ??


  12. arsi    13 Feb 2017 @ 14:02   

    thx nice drivers. is possible to get EQ “effects” to 2db steps instead of 4db. DGX user


    • CarvedInside    14 Feb 2017 @ 00:41   

      Depending on which audio panel you are using to set the EQ effects you could try the other ones. Try with C-Media Panel and XonarSwitch if you are using Asus Audio Center.


  13. Xing    13 Feb 2017 @ 17:21   

    Hi, my mic doesn’t work after installing the latest driver. DGX and WIN10


  14. Must1    14 Feb 2017 @ 14:01   

    Hi and thanx for the new drivers.
    Is a new driver mainly for STX II cards is planned ? (UNi Xonar STXII W10 1825 v1.81b ) ?

    Thank you.


  15. Kano    15 Feb 2017 @ 08:18   

    I can’t play sound through headphones and SPDIF at the same time on latest UNi drivers. I have previously been able to.


    • CarvedInside    15 Feb 2017 @ 13:36   

      Thanks for the feedback. Which are the previous drivers that worked fine in this regard? Which card do you have? Did you make any changes other than activating the SPDIF from Asus/Cmedia/XonarSwitch panel?


      • Kano    16 Feb 2017 @ 02:29   

        Previous drivers – 1.75+1.8.
        Card – Xonar STX.
        No other changes.
        With SPDIF ticked and selecting the output in music player to SPDIF the headphone sound will just stop operating.
