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. Jileo    20 May 2013 @ 17:42   

    Hello there! First, thanks for your work.
    I have a problem with the 1.71 version, the wasapi exlcusive mode in foobar doesn’t work anymore. A sound from an other app can be played while foobar/wasapi is mute.
    This works fine with the 1.61 version, right out of the box just after the installation of the 1.61.

    There is any clue ?


    • CarvedInside    21 May 2013 @ 09:53   

      I’m not sure what you refer while by “while foobar/wasapi is mute”. I just tested wasapi playback and its works fine. Stop and play again while having winamp play in the background also works.

      You might have unticked one or both “Exclusive Mode” options in the Volume->Playback devices->Asus Xonar (speakers and/or Digital out)->Proprieties->Advanced->Exclusive mode. Check that they are both ticked.

      If that is not the case, then try to update foobar, and also its components (from Preferences).

      Hope this helps


      • Jileo    21 May 2013 @ 15:28   

        Yes I have the two box checked for exclusive mode and foobar/components are up to date.
        I have tried to explain that the wasapi playback is muted when I play an other sound with an other app.
        For example: Foobar is playing -> launch vlc with a tune (or any app) -> vlc sound is ok while I cannot hear foobar’s sound anymore -> stop vlc -> foobar works fine.


        • CarvedInside    21 May 2013 @ 15:49   

          You’re using analog or SPDIF output? Have you applied any addons to the drivers (especially ASIO 1.0)?

          I suggest you try reinstalling 1.71 preferably doing a clean install detailed in FAQ Q&A 1


          • Jileo    21 May 2013 @ 18:38   

            Yes SPDIF output, any addon selected and I have done a clean install.
            I will retry anyway.


            • CarvedInside    21 May 2013 @ 19:53   

              While I can’t reproduce your problem, I guess it could also be a bug manifesting in some cases.
              By any addons, you mean want to say none?
              You didn’t mention your card and OS, please do.
              If no luck with the reinstall, try the drivers downwards from 1.71 and see which ones will work fine for you and let us know.


              • Jileo    21 May 2013 @ 21:38   

                Yes I use no addon, I have a Xonar DX with win7 x64 xsp1. I will try the 1.70 version, 1.64 beta and 1.61 works fine.


                • CarvedInside    22 May 2013 @ 17:51   

                  Its not uncommon for newer drivers to have new issues. You are perfectly fine if you use slightly older UNi Xonar driver releases if you have no problems with them.
                  Let me know if 1.70 will work fine or not.

      I can confirm Jileo’s problem. Exactly the same issue with analog out on my D2X card. Very strange problem. While you are playing any song through foobar WASAPI (event mode in my case) and try to play other audio stream simultaneously like flash or anything else. (normally you should not hear anything else except application using wasapi exclusive mode) Right after the other audio source start playing foobar immediately go ‘mute’ and you can’t hear totally nothing because the other audio is still blocked by wasapi exclusive mode. Funny situation. However I could clearly see that song is playing normally by spectrum analyzer and progress bar reacting. The only solution was to restart song or move progress bar a little bit. All tested on Win 7 Ultimate x86 and latest version of foobar and wasapi out plugin with correctly checked exclusive options in windows settings.

      BTW I tried clean install of the 1.71 driver two times thinking it will be some driver cleaning releated issue but now I see I’m not the only one facing this problem. Right after installation of 1.70 pack all issues disappeared immediately so it really looks like new bug.

    hi wanted to know if Xonar Phoebus driver are moddable?


    • CarvedInside    21 May 2013 @ 09:56   

      Can’t add support for Phoebus cards in UNi Xonar, because the drivers are totally different. And getting involved in a separate driver mod for Phoebus cards its very unlikely to happen. Sorry.


      • Szymon    17 Aug 2017 @ 23:43   

        I just became an owner of Phoebus after switching from D2/PM and I have to say I am disappointed. There’s still no chance for a proper UNI driver right?

        What card would you recommend that could replace D2/PM? I was using only optical cable to connect to my speakers and now it’s complicated as I have to switch to optical for stereo music and 5.1 analog jack-jack for non DTS movies and games. This is bollocks for the price of Phoebus so I will definitely try to change it. My fault that I didn’t do proper research as I was in a hurry.


        • CarvedInside    18 Aug 2017 @ 16:25   

          I don’t have any plans for modding Phoebus drivers. From what I understand, what you need is DTS encoding enabled on your card. I haven’t done such a thing for any “classic” Xonar cards.
          There might be a solution to get DTS encoding for some video players through AC3Filter. Guide here.
          Recommending a card would be based on how would you use it and why you don’t have the Xonar D2 anymore. Assuming you want a card with DTS encoding and would only like to use the digital output then the cheapest card with DTS encoding will be suffice. The Xonar DSX fits those requirements, but if you want to use analog as well then getting a pricier one would be recommended.
          FYI from a audio quality standpoint using the card’s digital output you are bypassing the card’s DAC and op-amps and use those in the speakers/receiver instead. Depending on the quality of the DAC in your speakers/receiver it might be better or worse than that in your sound card. If you want to use the audio card for the sound processing you will need to use the analog connections.

    Windows 8 64bit doesn’t work for me. Problem with driver signature, code 52. How to fix it?


  4. Jim M.    22 May 2013 @ 09:13   

    How do I solve the “please plug in your Xonar St card” error when the drivers try to nstall on my Essence ST? I had no luck with either the most recent version of the drivers on the ASUS site nor any of your versions. I am running Windows 7 64-bit. BTW, the device comes up in Device Manager in the Other Devices category as a Multimedia Audio Controller with the yellow warning sign. Thanks.


    • CarvedInside    22 May 2013 @ 17:55   

      In your case you might want to have a look at this page.
      There is a guide how to check if EEPROM is ok or not. If its OK then check this page: Driver signature – possible solutions & discussions page


      • Jim M.    23 May 2013 @ 20:12   

        Hi CarvedInside:

        Thanks for the tips. I first checked the EEPROM and it was not overwritten. I then tried to load the updated ASUS driver for WIndows 7 in Safe Mode and it worked!!! FInally, I wanted to try the latest Uni driver so I ran using the Driver Clean option also in Safe Mode and that worked as well.

        I was going nuts on the various blogs that offered suggestions and finding that nothing else worked and actually returned the card the first time thinking the card was bad..Thanks again!



  5. CalinTM    23 May 2013 @ 14:13   

    Basically the Low DPC Latency version, doesn’t put any kind of start-up to load, and basically works like the official asus driver for xonar DX, BUT doesn’t have GX, is that right ?


  6. Eldelasdudas    23 May 2013 @ 16:28   

    Hi, I have a question.
    Why 6 channel have woofer side instead of rear???


    • propheticus    26 May 2013 @ 14:18   

      A SUBwoofer plays sounds that are impossible for us to pinpoint the location. So placement doesn’t really matter apart from avoiding unwanted reflections of nearby walls or standing waves. The picture of the subwoofer on the side doesn’t matter, it’s non-directional, they just needed to place it somewhere. For all I care it could have been depicted as being vertically in front or above you…


  7. Zibi    23 May 2013 @ 21:43   

    hi, i cann’t install apps, “devcon is not found”


    • CarvedInside    24 May 2013 @ 11:51   

      You don’t install them, you extract them, open the folder of the application you need and run the .exe corresponding to the setting you want to apply. If you decide to move a .exe you also need to move the “\Devcon” folder.


  8. Felipe Batista    26 May 2013 @ 04:00   

    Hi, thanks a lot for your website you are helping a lot. But I noticed that my Eeprom was rewritten “(13F6:8788)”, So I to fix this I just would ‘reprogramming’ the eeprom? If I burn the program in a CD it is secure? Please, help me. See u.


    • CarvedInside    26 May 2013 @ 12:35   

      The only way to fix that is by reprogramming the EEPROM with the correct information. You want to ask if it is safe instead of secure? Even if it fails due to power loss or something, I think it won’t be a problem to redo. While I don’t think there is 100% guarantee for restoring the EEPROM, at this point thats the only way to go. Boot CD is the most easy and direct approach.
      Good luck:)


      • Felipe Batista    28 May 2013 @ 04:31   

        Well, I tried if the CD to install the driver (what is new for me, because I always just download from the website to use the newest version, so..). It took a long time but it finished well.
        my card was installed with the correct name ASUS Xonar DGX Audio Device / Manufacturer: ASUSTek / Digital Signer C-MEDIA ELECTRONICS INC. / Driver Version: I read about a guy that when fineshed the instalattion on the the device manager the name is just Asus Xonar DG (not DGX, but the card is a DGX) if a rewriten eeprom is possible to finish the instalation? I don’t know if it’s normal with the eeprom problem, but the hw ids still the same. I think the card have been working properly. Is ther other way to be sure about and test if i need to fix something on the eeprom? I’m sorry if I’m so insistent, but I need to be sure about. Thanks a lot guy. Do you have some fan page on facebook? Thanks again!


        • Felipe Batista    28 May 2013 @ 05:00   

          I think I have already answer my question, I just update again the driver if the windows wizard to version and crashed. The message is as follow:

          Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)”

          I just undo to the old version and the audio works again.

          So that is the proof that I needed? I will never be able to get the newest driver version until I fix the eeprom problem?

          Thanks again! I’m waiting for your answer!


          • CarvedInside    28 May 2013 @ 14:06   

            Well if there is a problem with EEPROM you get problems like driver not installing or its installing but you can’t access the Asus Xonar Audio Center.

            But that message I don’t think it has to do with EEPROM. You can try to install the drivers with the methods presented on this page. These kind of issues happen from time to time.
            Regardless if you manage to install the drivers, personally I would fix the issue with EEPROM, especially since your card still has warranty for now. But I don’t think there is a change that a EEPROM reflash would kill your card.

            Not a big fan of facebook, so no fan page. But if there will be one, there will be a facebook logo on the site.


  9. Skydawg    26 May 2013 @ 21:58   

    Just purchased a Xonar DX card and immediately started looking for modded drivers and obviously ran across your unified drivers. The problem I am having is Norton keeps pickig up all the driver packages and add-on packages as having a virus. WS.Reputation.1 Is this a concern?


    • CarvedInside    26 May 2013 @ 22:47   

      Certainly not, its a false positive. Its either because of the packaging of the drivers or because of the driver cleaner which deletes (driver) files from Windows folder. Here is a virustotal report for 1.71 r2.


      • Skydawg    26 May 2013 @ 23:44   

        Thanks for the reply. I almost certainly did not think there was a concern because I’ve read nothing but great reviews about your work. And I’m sorry to have posted something of this nature, but was more concerned that perhaps someone had hacked the files or hijacked the link. I’m looking forward to giving them a try.


  10. Digitalis    27 May 2013 @ 03:51   

    i have to comment. the unixonar 1.71 has the worst case of digititis i have ever heard in my system. this is present in any option whether low dpc latency or normal blah blah. this is not present in the ORIGINAL ASUS driver. FYI.


    • CarvedInside    28 May 2013 @ 13:47   

      I’m not familiar with this term digitalis. If you have a link to what it means or you can describe it to us, that would be great.Can you give us details about your setup OS, card, if you’ve used analog or digital output, and DirectSound, ASIO or WASAPI playback?
      If you’ve tried other Uni Xonar drivers, what about digitalis in them ?


    • propheticus    28 May 2013 @ 13:48   

      you must’ve screwed something up then. sounds perfectly fine here.


  11. Baroman    28 May 2013 @ 18:36   

    Trying to get the right setup for my 5.1 headset (cm sirus 5.1) on a d2x, any tips anyone? everything is just 2.0 atmo :/ for games, music and movies, using WinAmp, any suggestion would be great (Y)


  12. Elon    30 May 2013 @ 21:37   


    Have a Xonar DX2 card. Windows 8 x64. Only use sony mdr 7506 headphones, and it seems recently I can turn the volume up with any music, but it doesn’t get any louder after about hitting 40-50 on the volume slider. Checked different things, (made sure Windows volume decrease option is set to Do Nothing, headphones aren’t broke, etc) but can’t seem to figure it out. Was quite sure volume would always goes louder than you could handle it going all the way up to 100. Might it be something to do with later drivers or settings I’m missing?


    • CarvedInside    31 May 2013 @ 11:15   

      This could be from a number of things. Driver, windows and other software,configuration drivers or a hardware defect.
      You have settings for individual speakers/channels, for Asus Panel they are in the Mixer tab, check them out the channel sliders should be at 76, you can use reset.
      Other things you should try: Uninstall drivers and install them again. Try other driver releases. If you have another Windows installation on your computer (like Win7) try there. Might want to try your card in another system preferably with Win7.


  13. Benjamin Reilly    31 May 2013 @ 14:36   

    I’ve used again Xonar d2X after embedded audio due to high CPUusage installed original drivers without converter but high latency, then installed this last one and latency has decreased 3 times. Other feedback: audio latency affects also other cards inthe system, as my physic card by unixonar also this latency has decreased…


  14. Benjamin Reilly    01 Jun 2013 @ 13:50   

    to the author: it would be possible make a driver without xonar converter so to save other latency? thanks. Actually I can delete it from registry…. or installing driver without converter part only by my mod.


    • CarvedInside    02 Jun 2013 @ 15:04   

      I am planning on looking into this but I am very busy at the moment. Tell me which is the registry key you delete.


      • propheticus    04 Jun 2013 @ 16:57   

        found one that might be it: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}008\Drivers\mixer\wdmaud.drv
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{6994AD04-93EF-11D0-A3CC-00A0C9223196}\##?#PCI#VEN_13F6&DEV_8788&SUBSYS_84671043&REV_00#4&30D54F48&0&00F0#{6994ad04-93ef-11d0-a3cc-00a0c9223196}\#CP_Topology\Device Parameters

        I wonder. If youdelete the Xonar Audio converter, what will then convert (unsupported) formats? Window’s mixer? I think I’ll leave this one alone and leave converting to my xonar audio card.


  15. rankena    02 Jun 2013 @ 12:09   

    Benjamin Reilly ,please share your experience about deleting xonar converter from registry and installing drivers without this crap.
