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:

  • 1.75a “Standard”

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. Lipservice    14 Jun 2017 @ 06:01   

    Hello, I just purchased today an ASUS XONAR DSX 7.1 Channels 24-bit card. I am running Windows7 Professional 64bit. I will be using it strictly on my Onkyo Home Theater receiver. And only using the digital out on the card (optical out). The receiver is 7.1 channel. What would be the best driver for it?
    Thank you!


    • CarvedInside    14 Jun 2017 @ 15:33   

      Hello. Start with v1.80a, if you encounter any issues try v1.80b and then v1.75a.
      Since you are new to Xonar cards and their issues, before reporting any issues try the ASUS original drivers and see how they perform in that regard.


    • Kalle    13 Jul 2017 @ 21:39   

      So I’m running WIndows 10 64 bit and have a Asus Xonar DX card.

      I have tried both v1.81a r2 and v1.80a r3 but both causes BSOD from time to time.

  2. DGX User    17 Jun 2017 @ 19:34   

    Hi, i have DGX on S/PDIF (Win7x64), and i’m using v1.80a, sometimes after booting up, i have no audio output for few minutes, sound is playing, and bars in Control Panel are moving, but no audio at all, after few minutes it’s start playing as normal. I’m not doing anything, just suddenly starts playing. Is there any fix for this?
    On my old machine (IP35Pro 775) this begins in few months ago, after i moved to z270 nothing changed it’s doing again. :/


    • CarvedInside    17 Jun 2017 @ 22:59   

      It could be that there is something wrong with your card, maybe some capacitors are deteriorated. Check your card and see if there is any capacitors that leaked or are bulging.

      Or it could be an issue with the receiver/speakers again with its capacitors or something else. To check if the receiver has an issue you could start the receiver a few minutes earlier before starting the PC
      You could also use the onboard audio card if it has a S/PDIF output. In terms of sound quality there is no difference between a onboard and a dedicated audio card when using S/PDIF output.


  3. Evert    18 Jun 2017 @ 12:28   

    Does the drivers work in the latest Win 10 Insider Build?


  4. PALADiN    20 Jun 2017 @ 10:52   

    Is the Xonar D2X supposed to support spatial audio (introduced with Windows 10 1703) when using the 3.5mm jacks? I have the tab available in the playback device properties but the only option I can select is “None” when using the official ASUS driver.


  5. Kyle    23 Jun 2017 @ 06:43   

    Xonar essence ST, sound only works for a few seconds on restarting my computer then it stops, tested using all different variations of drivers, running windows 10 enterprise. Unsure of the problem, anyone had this before?


    • CarvedInside    23 Jun 2017 @ 12:00   

      When it’s not working, open Device Manager->”Sound,video …”->Asus Xonar ST card proprieties. What does it say under “Device status”?
      Which build number your Windows is?

        Says working properly no error code. Windows build #10240 Windows 10 Enterprise N version 10.

          When it’s not working, go to Windows Volume->”Playback devices”, does Speakers (Xonar ST Device) show sound activity? On the same Playback devices window, double click the Speakers and go to Advanced tab and untick “Allow applications to take exclusive control …” see if this helps.
          You should check that your speakers aren’t the problem. You should also test your ST card in another PC.

            Found out the problem, “Startech PCI-e to PCI adapter” is the culprit. I have a rampage V extreme with no PCI slots. Hate to see this card go though, changed out the op amps and did a few tweaks here and there. Going to give a different brand adapter a try and see if I have luck, if not looks like Fenix HT Omega is going to be my next card 🙁 ! Thanks for your help!

    j’ai acheté une carte son phoebus solo or les drivers ne fonctionnent pas ni ceux trouvés sur le site d’asus, où puis je trouver des drivers fonctionnels pour ma XONAR PHOEBUS SOLO ?
    j’ai lu qu’ils fallait telecharger les drivers unifiés or je ne les trouve pas sur le net



    • CarvedInside    24 Jun 2017 @ 19:07   

      English is the only language allowed here.
      UNi Xonar drivers do not work with Xonar Phoebus cards. As far as I know there aren’t any modded drivers for Xonar Phoebus cards.

    I’m using Xonar DSX driver for Windows 10
    Xonar DSX driver (ver. , Audio Center version: )

    this is the latest official driver from the website of asus
    and I heard about uni drivers, so what are the advantages of uni driver over the latest official drivers, are these advantages in term of sound quality and optimum surrounding sound? waiting for the answer


  9. kritican    30 Jun 2017 @ 18:31   

    i was have xonar dx and then i sell her cause i think she doesnt work correctly and now i have xonar dsx and i still cant use 6 channels on logitech z906. can somebody tell me what i need to do. i try with few uni xonar drivers and still doesnt work i try find something in windows settings and nothing work. so can anyone tell me which drivers works on dsx or what i need to do to get real surround sound… pls help im tired of this shit

      I will take this opportunity to tell you that if you sold a card that you thought was defective that was wrong.
      Now getting to the problem you are having. How are you connecting the speakers to the soundcard, analog or digital (S/PDIF) cable?
      If you are using the S/PDIF connection then you need to:
      1)set “DTS Interactive” encoding in S/PDIF Out menu in ASUS Audio Center or C-Media panel
      2)check that your speakers are set to DTS decoding.

    Link State Power Management might be the complication that forced me to reinstall both the XONAR® Audio Center™ and the MaxedTech® UNi XONAR Audio Software™ in Safe Mode when the 1630 still ran Windows 7.

    Hey, to begin with I must say I am really thankful for your modded drivers, I’ve been using them since way back in 2013 with my STX card and it has worked flawlessly so far, thank you! 🙂

    Also I am unsure if this is really up to you and I don’t think It’s a super big deal but I just inserted the STX II into my machine and the DPC latency is about 35-40 higher versus when I had the normal STX card, I use the “UNi Xonar STXII 11.5 v1.80b r3” driver which I take it is the recommended one to use, do you think I could have better success with other drivers, I did try 1.75b same results, or do you think this is something that can be improved down the line with driver updates?! I figured if it’s in Asus or Cmedia’s hands I would better start believing in santa claus than wishing for them to get there beep’s together.. 😀


    • CarvedInside    09 Jul 2017 @ 17:01   

      Hi. The higher DPC latency could come from some STXII card specific subroutines in the drivers that aren’t optimized. I suggest you try the “a” drivers and see if higher DPC Latency situation improves.
      Speaking of DPC Latency, I am working on a new tweak that would reduce the DPC Latency for all cards. While it’s not directly related to your problem I will be interested in the DPC Latency results on your card. I hope I will be able to make this tweak availabe for testing sometime next week.


      • Sam    14 Jul 2017 @ 04:20   

        Hi. Thanks for the tip! While I have not gather enough courage to run Windows in test mode yet I will probably try it out later just to see if the “a” driver does indeed give me any better latency!

        About your new tweak decreasing DPC latency on all cards sounds amazing.. Wasn’t expecting it was even possible without Asus or Cmedia actually doing something from their end!! But glad to hear you are at least trying to improve it even if it might only be a small bit, I will for sure let you know how it worked for me as soon as I can try it out! 🙂


        • CarvedInside    15 Jul 2017 @ 17:57   

          You can install v1.80a drivers with “Disable Driver Signature Enforcement method” instead and restart normally after that.

          Small improvements here and there can be done without having the driver source code, but that research requires a lot of time and effort. Took me a while and now I finally have something new that may be usefull. You can now check the new DPC Latency lowering tweak here. I look forward to your feedback.

    Hello. I’m using W10 Creators Update now. And my problem is so strange. When i try to listen music in AIMP, try to watch videos in youtube or in videoplayer after 5-10 seconds of playing my STX clicks and sound is turn off in system compeletely. After that click mouse start freezing some time about 10 seconds and became normal after that. Device Manager says STX is OK and works normally. Sound turn on after rebooting the system. Try to install 2 latest drivers. No luck.


    • CarvedInside    07 Jul 2017 @ 06:14   

      Check that your auxiliary power connector is properly connected to the card.
      You should try your card in another PC preferably with Windows 7 or Windows 8.


      • slavutich32    08 Jul 2017 @ 08:57   

        Thanks for help. I already found solution – CPU overclocking via clock generator. Put it in 100MHz and problem is gone. Anyway, thx for your help here and unified drivers of course!


  13. Elisey    09 Jul 2017 @ 17:56   

    Hello CarvedInside! can you help me or say some tips. I got Xonar STX and DT 990 Pro 250 Ohm, which settings better for this headphones, High Gain or for 64~300Ohms or Extra High Gain for 300~600Ohm ? 🙂


    • DioExtreme    09 Jul 2017 @ 22:26   

      Extra High Gain does have a little more detail for me but that might be because of the upgraded opamps I have.
      Either works fine though, just don’t go too high on volume with Extra High Gain.


    • billgates    11 Jul 2017 @ 20:57   

      Extra High Gain is always the best. Even on low impedance headphones. I don’t know how, but the driver ruin sound quality bigger on lower impedance setting.
      On Extra High Gain sound is clearer, warmer and integral.

    Hey guys. Been using my Xonar D2X for… well a while. I just had a thought though- what else is out there that supports either DD:Live or DTS:Interactive for sending 5.1 over optical? My reason for getting the card ages ago was to sling true surround sound to my AVR without having the run HDMI through it (added cables, and no video/audio independence). Since the issue I had with my sound card and the creators update has meant I’m sticking with anniversary for the foreseeable future it got me thinking- what else is out there? What other sound cards exist that can run DD:L or DTS:I over optical? What do other people use? Or am I in a tiny minority with anyone who wants true surround moving to an HDMI solution?


  15. Hello    18 Jul 2017 @ 13:11   

    Hello I have not used your drivers but am having a problem with my xonar dgx possibly and have searched around the internet for help with it and found your forum through suggestions to install these drivers. I just bought the card recently (couple weeks) and last night I had the left ear of my headphones stop outputting sound but if I changed the analog out setting to something like 5.1 or 2 or 4 speakers the left ear would start outputting sound again but not if I set back to headphone. I restarted and shutdown/rebooted several times and it didn’t seem to help but now I woke up this morning and booted up and now it is working in headphone mode. I know this is probably not the place to ask but do you know what the problem could be? I am wary of using your drivers as it says it has problems like BSOD with windows 10 which I am using.


    • CarvedInside    18 Jul 2017 @ 13:56   

      Hello. Maybe the problem is hardware related because when you enable headphone mode the card uses the headphone amplifier that is not enabled when using 2, 4 and 5.1 channels analog output.
      UNi Xonar drivers aren’t more prone to BSOD with Windows 10 than ASUS Xonar drivers. The “Notes about Windows 10 compatibility” are valid for ASUS original drivers as well.
      So you can try the UNi Xonar drivers without worry. I assume you are using ASUS Xonar 1823 drivers, in your case since you have this left headphone not working problem I suggest you try UNi Xonar drivers with different audio drivers, so I recommend trying v1.81a and v.180b drivers.
