    My card would work for a moment, and then I load PUBG and bam, it's soft as hell, and some frequencies are too soft. All sound sounds muffled. But then windows sounds come through loud. But all audio is messed up. (Videos, audio, etc).

    Now doesn't matter what driver or how many restarts, still screwed. Think it's time to plug my Essence STX into another PC and see if the card died, or if it's Win 10 1709.

    FYI Everyone with the sound resetting issue on FCU windows 10. The issue has been fixed with insiders build 1709 build 1704 and on. I have verified it.


    • CarvedInside29 Jan 2018 @ 20:35

      Thank you for the information. I think you meant Window 10 version 1803 insiders build 17040 or 17004. Please clarify the exact build number.
      Btw Until now I made the confusion of calling Windows 10 versions as build numbers.

    Hello, I am thinking to buy second hand xonar d2. Should i make this movement 'cause depending on latest comments on this page, drivers are seems kindy problematic. I am using latest windows 10 version and updates. Let me ask one more question? If i had xonar d2, which version should i have to use?


    • CarvedInside30 Jan 2018 @ 18:35

      Some problems are from the drivers and some problems are from Windows 10 and are happening other cards as well.
      You should know that the Xonar cards are no longer supported by ASUS and audio chip maker C-media. If M$ decides to make some drastic changes to Windows 10 audio, the Xonar cards may end up not working anymore and there won't be any fix.
      I would advise getting the a D2X or DX instead, because if you upgrade your PC you may not have the PCI slot required by the D2 card.

    I'm grateful that the UNI drivers exist and are still maintained. I'm in a serious bind. I've been using a Xonar DGX card for 2 years. It has been detected by Win 10 automatically. Within the last 7 days, I got messages that the DGX was not correctly detected. Running the "Resolve Audio Problems" applet resolved my issues. **I only use the DGX to run 1 optical output to an external DAC and 1 bog-standard mini-jack input microphone. -----On Saturday, being a 'tidy' pc conservator, I tried to reinstall the Xonar driver with an Asus update: every card option failed. ----I uninstalled the ASUS driver and installed the UNI most recent Beta: no change (but blue screens). I uninstalled the beta and installed the Stable 1822-1.75ar3: the Xonar card *showed* all was well, and the DAC even showed a signal lock. But I could get no output sound from either of the detected output sources. -----[I then uninstalled and removed the Xonar card and attempted to installl the original and four variants of the Realtek drivers for the mobo integrated audio. Have restarted the machine 50 times in the last three days. Confusion and despair have resulted.]

    --I want to try to reinstall the Xonar DGX card a last time. My experience has been that if it is installed first in Win7/8 and the OS updated to Win10---or if it is installed immediately with a fresh Win10 install---it will function with the ASUS drivers. I appeal for suggestions from you and the community. I have read the Trouble-shooting guides and these responses in the thread. I have run the Xonar driver uninstaller and Driver Fusion to remove any vestiges. Are there any specific recommendations anyone would make for installing the Xonar DGX with Win10x64 (Creator's Edition) installed (I can't roll back the update)? I only need optical out and a single crummy mic in to work. Thank you.


    • CarvedInside08 Feb 2018 @ 05:01

      If I understood correctly, you've tried the S/PDIF output of your Realtek card and that didn't work either. If that's the case then your problem most likely is from the connection or DAC and not the soundcard.


  5. SaGaIn07 Feb 2018 @ 15:13

    If ASUS and CMedia does not support xonar cards anymore, why dont they give the driver sourcecode out to help ppl. who want to develop new driver. Could you develop a new driver from start? Maybe it would be better than the buggy official... The xonar STX is still a very good card but without support its almost crap.


    • CarvedInside07 Feb 2018 @ 22:09

      I can't do that. Making a new driver from start would take huge amounts of work and it will lack proprietary protocols like SPDIF Dolby Live encoding and others.

    • CarvedInside08 Feb 2018 @ 22:39

      Thank you for the feedback.


      • Darko08 Feb 2018 @ 22:54

        The Xonar DSX still kicks ass ! I have also Soundblaster Z and bought DSX intentional for my media PC I tested it in my Omen first and WOOOW!!!! I was surprised how much better the Xonar sounds then SBZ on all levels and fields so I decided to keep it in my gaming rig and bought another one also DSX for my media PC . I will keep SBZ as backup In case Xonar wont be working properly due to lack of driver support in some future time. I also opened a complained ticket by Asus regarding future driver updates .
        I love DTS and everything DTS related and XONAR DSX si the KING in this field .
        Thank you for keeping the Xonar alive !
        P.S: original ASUS drivers from (2015) also working without any problems on the same system , but I prefer this package .


        • CarvedInside12 Feb 2018 @ 00:08

          Let us know if they have something to say about future driver updates. I suspect they will say something like they continue to support the cards.


          • LOJ19 Feb 2018 @ 22:49

            Hey DARKO and Carved, let me ask a question from a noob guy =D, using the Z906 via TOS isn't bypassing all the benefits from DSX?

            Thanks in advance.


            • CarvedInside21 Feb 2018 @ 00:05

              Hi. By using the audio card optical output you are bypassing the card's DAC and op-amps and use those in the speakers instead. Depending on the quality of the DAC and op-amps in those speakers, the sound might be better or worse than from your sound card. If you want to use the audio card for the sound processing you will need to use the analog connections.


          • Darko20 Feb 2018 @ 03:00

            Im quite shocked by the answer ?? In fact I have no idea what he is saying ??? like there might be only if there is some incompatibility issue or what ??
            “Dear Valued Customer,

            Thank you for contacting ASUS and your feedback as well.
            The card was realesed in 2014 and the updates will be as per the hardware support and bugs which are will be found or reported by customers. ASUS simply cannot update the software when the hard ware too supported. Thank you for understanding.

            Kind regards,

    Hi ! I was wondering if there was any update on Asus website for Asus Xonar DX soundcard and it appears that there is nothing up to date. Trying to know the best configuration for my soundcard when used with a brand new Sennheiser Game One, I went from forums to forums and finally came here because other people mentionned the Uni Drivers !

    What would be the best choice from your drivers library for Windows 10 + Sennheiser Game One + Asus Xonar DX ?

    At the moment, I'm running Asus drivers from 2015 but I find the Dolby and the Virtual Surround a bit clunky (it does like metallic noises...).

    Thank you !


    • CarvedInside12 Feb 2018 @ 00:05

      Hi. It depends on your needs and issues. Maybe you should start with 1.80a since these use the same audio drivers as ASUS latest but with additional fixes. From there go try the others see if there is one that performs better for your needs.
      I suggest you check the FAQ Q&A 9 for suggestions on how to properly configure the audio settings.


      • nGile13 Feb 2018 @ 19:26

        Hi. Thank you for your reply. I think the Virtual Surround for headset is really not for me. I don't like the way it sound and it is really not the same as a real 7.1 speaker system. My Sennheiser Game One is brand new. Maybe I need a burn in track in order to optimize it ?

        I still didn't try the UNI drivers. I'm afraid of a BSOD or something that could make my PC crash.

        What do you think ?


        • CarvedInside13 Feb 2018 @ 23:02

          I don't know if your Sennheiser headphones need a burn in period.
          UNi Xonar drivers won't crash your system any more than original drivers.


  8. Chris Leipold13 Feb 2018 @ 20:32

    Latest Windows 10 Fall Creators Update monthly update to latest build February 13, 2018—KB4074588 (OS Build 16299.248) includes an interesting fix: -Addresses issue where surround sound audio endpoints reverted to stereo after restarting.


    I am going to update and test it right now.


    • CarvedInside13 Feb 2018 @ 23:18

      Thanks for the heads up. Let us know if it fixed the issue and if the other issue with settings being reset when Windows Volume is clicked was fixed as well.


  9. Ben14 Feb 2018 @ 08:53

    Hi and thanks for your work but I have one question, will we ever get a new version?


  10. Erik20 Feb 2018 @ 22:27

    Hi! I just installed win10 today after using win7. My Xonar essence stx (i dont know wich one, but a very old one) stoped working, i tried drivers from Asus and i tried yours but i got nothing. I can see in my sound settings that the "volume" moves when i play an audiofile but i cant hear anything. My headphones works when i use the sound from my motherboard, i tried to disable motherboard audio in bios but nothing helps. Any idea?


    • CarvedInside21 Feb 2018 @ 00:20

      Hi. Is the card detected in Device Manager -> Sound, video (…)? Does it say that "Device is working properly" under "Device status" in ASUS Xonar STX Proprieties?
      Are you using analog(jacks) or S/PDIF output? Are you headphones connected to the front panel or to the rear of the card?
      If you right click Windows Volume and select Playback Devices, is the "Speakers Asus Xonar(..)" set as default device?


      • Erik21 Feb 2018 @ 19:41

        Hi! Working properly. Using Analog and its connected to the rear of the card and Asus Xonar set as default. Maybe the card is broken but thats also abit weird that it would break exactly the same time as i install win10.


        • CarvedInside22 Feb 2018 @ 00:16

          Which Windows 10 version do you have installed?
          To see if your card is the problem, you should install windows 7 on a another partition or check your card in another PC preferably with windows 7 or 8.1 and see if it works.


  11. Darko26 Feb 2018 @ 20:46

    is there any any interesting custom XONAR skins available ? link or something?


  12. PadreMarty04 Mar 2018 @ 13:50


    I build myself a new PC. And of course i took my STXII with me. Everything seemed alright. I installed the newest 1.81a R2 driver and had no problems. Until i played CS GO. I got microstuttering all the time. I downgraded graphicsdriver, reinstalled CS GO complete without old cfg files. But no solution. Then i started to use other UniXonar drivers. Now i am at 1.75b R3. And it seems that the problem is gone. I played for a few minutes on Valve Deathmatch server to test it. And so far it seems ok again. I report back here if i get problems again or if it stays "fixed".

    System Info:
    Windows 10 x64 1709 Build 16299.125
    Intel i9 7900X
    64GB DDR4 RAM
    Asus X299 Prime Deluxe (Onboard sound deactivated)
    nvidia GTX Titan Xp


    • PadreMarty18 Mar 2018 @ 00:09

      I forgot to report back. It wasn't the fault of the Xonar Driver for sure. For whatever reason now i have to use high performance in energy settings for CSGO.


  13. Troy04 Mar 2018 @ 19:12

    I have a Xonar Hdav 1.3 on Windows 10 build 17604 (64).
    I've tried the [UNi Xonar W10 1825 v1.81a r2] driver and it was no go.


  14. kean3D05 Mar 2018 @ 03:08

    hi i have a question, i have a STX I with drivers 1825 v1.81
    the asio version is
    now maybe i will buy a STX II, i see that latest drivers are the same so
    with the STX II did will be installed the .14 version or still .12 with those driver?
    and i case did i can switch changing the two dll cmasiop(x) (not possible with the STX 1) as i have


    • CarvedInside05 Mar 2018 @ 08:24

      ASIO is tied to STXII 1.80b drivers and doesn't work with standard drivers. So regardless of audio card, when installing 1.81a drivers you will get ASIO and it cannot be replaced. You can install 1.80b drivers for your STX if you want to check ASIO.


      • kean3D07 Mar 2018 @ 02:04

        thanks for reply, waiting for the stx ii
        would ask if for the stx ii better the 1.81 unified drivers or their own older 1.80b?
        the 1.81 works great with stx i on win10 fcu, and with the "disable speaker compensation" tweak too


  15. Zsolt08 Mar 2018 @ 13:25


    What's the status of these drivers on recent Windows 10 versions? When I tried it with my Xonar D1 1.5 year or so ago I had constant crackling which was impossible to resolve.
    Does anyone use a Xonar card on "Redstone 4"? (Which is near release I believe)

    "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"

    This is not encouraging... I quite often have to disable/enable the card when the sound gets screwed up (The left channel becomes silent). I suppose this didn't change since the release note was made?


    • Zsolt10 Mar 2018 @ 16:54

      By the way, how should I interptret the win 10 compatibility section.
      Are the issues mentioned for the earlier versions still present in later ones since they're not noted to be fixed?
      For example are these still happening: "unbalanced audio mix with Dolby Headphone", "random BSODs while watching youtube or playing movies" ?

      Some of the links are broken (and others will be broken) because they neglect a page number. For example the ones in the "Drivers above 1821 v1.71 may cause BSOD when waking system from sleep" section


      • CarvedInside11 Mar 2018 @ 18:55

        Thank you for the heads up on the broken links.

        About the Win 10 compatibility section, I don't have information on those that aren't marked as fixed. They could be fixed after some update, could be fixed in any of the newer Windows 10 versions or could still happening in that Windows version and any of the follow-up versions. Also, some issues are only happening for some people.


      • Case11 Mar 2018 @ 23:56

        I was the one reporting the unbalanced audio with Dolby Headphone and, as I've already mentioned in one of the comments before, I honestly can't tell if it's still happening and I just don't notice it as much anymore, or if it went away at some point. Anyway, I'm no longer using Dolby Headphone directly from the card control panel, I tend to use the HeSuVi app ( https://sourceforge.net/projects/hesuvi/ ) and alternate between several presets as needed there.


    • CarvedInside11 Mar 2018 @ 19:19

      The constant crackling issue that you had is not a something that happens to vast majority. Don't know if you would still have that with upcoming Windows 10 version.
      The BSOD when the card is restarted with 1825 drivers is still happening. It is something that could only be fixed in a future audio driver. You don't have install 1825 drivers, you could install any of the older drivers. Probably won't be missing anything.
