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.

The 1.75 drivers come in two variants:

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.

  1. Denis    02 Aug 2016 @ 10:04   

    hello thanks, great drivers, on my essence stx on win10 (c-media install/panel type) i got just few problems with asio crash sometimes on fl studio, that seems is not present on the originals ones (but they sux alot not only on asio!)
    did it’s cause the original asus drivers are a more updated version? (sign is september 2015 vs lastest uni xonar june 2015)


    • CarvedInside    02 Aug 2016 @ 14:32   

      ASUS original drivers are not newer than UNi Xonar drivers. In this case, if you’ve installed 1.80a drivers both use the same audio drivers (version 1823) and same ASIO driver component version. I don’t see any reason why ASIO output would work better with ASUS original drivers. Maybe the conditions on which you’ve tested are different like other program running or some newer windows updates where applied. You should do a drivers uninstall and reinstall the UNi Xonar drivers with driver cleaning option enabled in case something when wrong the first install.


  2. Arion    02 Aug 2016 @ 17:19   

    Hello there.
    I just found this on the web. Is this going to have any kind of impact on your UniXonar drivers in the latest Windows 10 Anniversary Update?


    • Cyril    03 Aug 2016 @ 02:01   

      I get the issue. Drivers are not longer available with Win 10 1607.
      A message about card power supply appears always when you try to launch audio center,…


      • CarvedInside    03 Aug 2016 @ 15:34   

        Did you make a clean Windows 10 b1607 installation or a update from a previous build?
        If you go to Device Mananger, does the card shown as installed under “Sound, video…”? If it’s shown as installed what’s it say under Device Status if you double click the Xonar card? Thanks.


        • Arion    03 Aug 2016 @ 18:29   

          I made a clean install with format. The drivers installed normally without an issue. The card appears in Device Manager and everything works. (I’m a normal user games,flacs,mp3s). I didn’t notice anything strange yet. Everything seems ok for now. Will this impact any future UniXonar drivers (If you release any)? I’m asking because I don’t quite understand what exactly they did with the signing and if this will affect “unofficial” drivers like yours or not.


          • CarvedInside    03 Aug 2016 @ 20:27   

            Thanks for the feedback. I don’t know if it will be a problem since there are many conditions and exceptions to this new driver signature enforcement policy. If it will be a problem then it would be for ASUS original drivers as well since I use the same driver files and digital signatures as they do and the changes I made to the drivers where to the configuration files not the driver files.


            • Jay    04 Aug 2016 @ 02:19   

              I’ve been using the drivers fine as an Insider for some time now. I’ve had issues with some stuff like newer AMD drivers (which can be worked around by turning Secure Boot off), but no issues whatsoever with the Uni’s.


              • CarvedInside    04 Aug 2016 @ 11:45

                  Some more feedback for Windows 10 Anniversary Edition in combination with UNi Xonar STXII 11.5 v1.80b r3 (Mainboard: ASUS Maximus Formula VIII, BIOS 1902):
                  – The drivers were indeed *disabled* after the update.
                  – However, after rebooting with driver signature enforcement disabled, they could be re-installed without a problem
                  – The STX II is recognized without any issues (currently in Low-DPC mode)
                  – MicMute / XonarSwitch are functioning flawlessly, too

                  Thank you for this, by the way. Absolutely great stuff!

                    As I know, older drivers than 09-2015 still will be installed. Even if they are self signed.
                    But nobody knows what future Win updates brings – it looks like the beginning of a big plan to make windows bsod free (does not work very well on my machine, even with sign drivers there are usb caused bsod´s 🙂

                    Im not 100% sure about the policy, but unixonars works fine on my machine, with a fresh install of 1607 Anniversary…
                    If not on your machine, try to disable secure boot in the uefi (can cause security problems if you don´t have brain.exe installed 🙂

        Xonar DX on Anniversary Edition, clean install, no problem installing driver, did not even had to disable driver signature enforcement and drivers seems to work perfectly.

        P.S: I am new to this though, front panel audio doesn’t seem to switch automatically, is that normal? Thanks

    awesome drivers. installed flawlessly on win 10 anniversary with the “reboot to “Disable driver signature enforcement”” method. I only had a small problem with AVG – it detected CmeAuVist64.exe while installing the drivers. had to add the exe to the exceptions.


    • CarvedInside    04 Aug 2016 @ 11:44   

      Thanks for the feedback. Did you try installing the drivers without rebooting with “Disable driver signature enforcement” and it did not work? Which driver version have you installed?


      • BBQigniter    09 Aug 2016 @ 11:47   

        sry, for the later answer. yes, I also tried to install your latest drivers normally after the anniversary update because the card wasn’t correctly recognized anymore. but it didn’t work, the setup ran ok without problems but didn’t have any affect.


  4. larry    03 Aug 2016 @ 21:05   

    upgrade keeps them clean fortunately…

    I’ve a very high DPC latency even if I use the Low-DPC install method – 1000µs (1.0 ms) for watching a 1080p movie in VLC!!
    I’m using LatencyMon for monitoring & it says I’m getting audio crackling etc.
    My soundcard is the Asus DG & I’m using Win10 64bit.

    Updated to the Windows 10 Anniversary update. Drivers still work for me.
    They did say that only for Clean Installs would it not work. But if you just do a plain upgrade from an existing install, it will still load your older drivers, signed or not. Meaning if you want to do a clean install of Windows 10 in the near future, you should do it with an ISO from before the anniversary update, install your drivers and then update to the anniversary update.


  7. evet    04 Aug 2016 @ 08:48   

    i’ve upgrded too and while the drivers are working the volume is very low for some reason.


    • evet    04 Aug 2016 @ 11:52   

      apparntly the problem is with mpc-hc stable build and not with the drivers. mpc-hc nightly works fine.


  8. bleibach    04 Aug 2016 @ 21:59   

    For me the latest driver works well from update to Windows 10 Anniversary update!
    but i have to clean install my system on Windows 10 Anniversary update and after installing the latest build the microphone is not working anymore 🙁
    are you guys working on an fix?

    Ok it was my mistake. How to Fix:
    Front mic was set as default in Xonar Settings. Changing to “normal” microphone works now.

    So After clean installing latest WINDOWS AU drivers work without any problem Asus Xonar DGX


  9. Cornea    05 Aug 2016 @ 03:14   

    I had Uni drivers and updated with anniversary updates. Everything still working perfectly 🙂 Haven’t tried reinstalling though.


  10. st0neh    05 Aug 2016 @ 03:15   

    Well this is an awesome update. When my entire system isn’t locking up randomly, half the time my Xonar DGX isn’t even detected by Windows on boot. I even had it disappear while the system was up and running. Never had a single issue until the AU.

    Thanks Microsoft.

    We are only playing music with Foobar and ASIO (no interaction with the system while playing) We always used uni-xonar drivers to good effect with the mark one xonar card on w10.

    We installed the Asus official drivers with the new mk2 card and all sounded very good. But for the sake of comparison, we just tried un-xonar drivers (low latency) with our new card. I expected no change in sound but hoped to reduce the ASIO latency (on this hardware we get dropouts at lower levels).

    Whereas uni-xonar is very natural sounding it seemed noticeably ‘more distant’ (meaning probably a touch more mid tone, or perhaps less precision in the top end. This was not a side by side comparison – therefore we could be deluding ourselves. Is it likely we were? There were definitely some changes – with uni-xonar there was a click when starting a song which does not happen with the Asus driver on this system.

    The uni-xonar driver did not permit us to reduce the ASIO latency setting to any good effect. We ended up getting clicks and drop outs at around the same level where we did with the Asus driver. Tried 32 bit and as per your advice, it sounded worse than 24bit which is what the card uses. I heard that 32 might be good since the data channel on the motherboard would be 32.

    We have reverted to the official Asus driver again.

    We have never noticed any change in sound quality with either drivers when setting the ASIO latency very low (80, where we get almost no clicks etc). Is there any advantage in sound quality terms for low latency for cached streaming music on a machine where there is little user interaction and minimal background processes interrupting?

    It seems common sense that low latency is required in most other circumstances.

    thanks for any thoughts

    w10 1607 clean install

    installed ok and working fine so far

    I have installed the 1.80a drivers on my Xonar and there were no issues. Low DSP setting. However, this isn’t a clean install, I reinstalled over existing drivers so I can’t confirm 100% this is always working for all Windows installations.

    However, to remove the balance bug (Right speaker was way too low volume) I had to manually delete HsMgr.exe from the Windows folder, then reboot. It’s like magic. Now everything is crisp and clear.

    The only plaguing issue I have is sometimes the card goes into “RANDOM MAXIMUM WHITE NOISE MODE” and screams out of nowhere. If I have headphones, it’s instant panic. I strongly suggest you keep your hardware settings as low as possible and increase your software levels instead so that when it happens, it’s a lot less worse. If you keep your amped speakers very high, it’s going to jerk you off your seat.

    In essence after all this I strongly discourage anyone from buying a Xonar chip. It’s an excellent piece of hardware no contest, but the driver implementation leaves to be desired. If I didn’t have MaxedTech, I would have snapped this card in 2, literally. In my hands. I also overpaid a bit for it I admit, 130$. Saw it on sale on the internet for 100$ after that. I guess its even lower now.

    I’d use my on-board sound, but there is a bug with Stereo Expansion where it doesnt work unless I pick an EAX Environment. It’s terrible.


    • CarvedInside    12 Aug 2016 @ 14:23   

      By “Low DSP setting” you mean Low DPC Latency? Cause if you’ve installed drivers with “Low DPC Latency” or “C-media Panel” configuration then the HsMgr.exe is practically deactivated and deleting it from Windows folder doesn’t have any effect at all.
      Your feedback is based on using Windows 10 or Windows 7/8?


      • Jean-Francois Beaulieu    16 Aug 2016 @ 18:06   

        Sorry yes Low DPC. I preemptively deleted it because I had problems last time with another setting. Thank you.


  14. Marok    12 Aug 2016 @ 13:25   

    I just did a clean install of Windows 10 (1607), and it seems like I’m able to install the 1.80a driver without any issues. I didn’t have to disable secure boot, driver signature enforcement, or anything like that.


  15. Laamapalmu    12 Aug 2016 @ 18:12   

    I installed 1.80a/b version for win 10 pro anniversary. I can’t get my mic to work. Phantom power gives power and the mic is ok. I’m using rear panel and using the microphone as input source at Xonar control panel. Still no audio after reboot or reinstalling drivers. Any ideas?
