    Hello Guys,
    I have a Xonar DSX and everytime I put pc to sleep, when I turn it on, the microphone is broken with strange loud noises.
    Anybody else experiencing this?


  2. Brandon03 Sep 2015 @ 05:06

    Does anyone know how to get Dolby Headphone to work with the RCA outputs of the Xonar STX? I would like to use this feature with an external pre-amp.


    • Jason07 Sep 2015 @ 00:42

      Dolby is a digital feature, and RCA is an analogue connector.


      • CarvedInside07 Sep 2015 @ 10:56

        You are wrong. Dolby Headphone is a sound effect that works on analog outputs. Dolby Digital Live is an encoding used for digital outputs.

    @CarvedInside the official Win 10 drivers for the STX has been released!


    • CarvedInside06 Sep 2015 @ 15:24

      Thank you for the heads up.


      • Chris Leipold10 Sep 2015 @ 13:13

        Are u planning to release a new Uni Xonar Package with the 1823 driver version?


        • CarvedInside11 Sep 2015 @ 00:28

          Yes. I am working on the new UNi Xonar driver package as we speak. I don't know when I will be able to finish. Hopefully it won't take more than a couple of days.


          • Wulfgar11 Sep 2015 @ 16:48

            The ST drivers aren't there yet (maybe they will be released soon). Are the new UNi gonna work for the ST also or you need to wait Asus' officials for ST to integrate them into UNi's package? Cause I want to use your drivers instead of Asus'. Thanks


            • CarvedInside11 Sep 2015 @ 20:26

              They will work. The new UNi Xonar drivers will work for all UNi Xonar supported card except maybe STXII.


              • Wulfgar14 Sep 2015 @ 13:30

                I've downloaded the ones for STX (W10 x64) just to see the asio version in cmasiop.dll, it's still while the STXII has Why it can't be updated for ST(X) too to version .14? Is there a reason for that? Thanks


          • Chris Leipold11 Sep 2015 @ 19:53

            Thanks for the information, that are great news and its good to hear! As always take ur time and i am looking forward to a release of the new driver pack maybe in the next days. Thumbs up & Greetz


    • jochem van kasteren06 Sep 2015 @ 16:27

      they are not on the asus website i cant find them


      • jochem van kasteren06 Sep 2015 @ 17:13

        i found them and installed them after like 30 minutes troubleshooting you need to remove the old drivers and install the new stx drivers in safe mode otherwise it wont install

        it would be great when the unified drivers will be released i will use them over the official drivers from asus
        thanks alot


  5. rBose07 Sep 2015 @ 10:16

    Any news for drivers for d2/pm ?


  6. Mark S08 Sep 2015 @ 10:43

    Help! Have had xomar ST working on my windows 7 home theater pc for 2 years. Last week I was doing driver updates on various devices. After updating the AMD catalyst package, I couldn't get the xonar app to launch. The shortcut was still on taskbar but nothing happens. In control panel the description was there but no info re: size of program, etc.

    I tried reinstalling the drivers from the supplied disc. The process is hanging at the point where I get the small grey window "installing ASUS Xonar Essence ST Audio driver..." the blue bar just keeps scrolling. There's no "cancel' button. I can't turn off w/o risking damage. I've tried that and I had to do a system restore back to a few weeks ago. That restore did not fix the Xonar issue though.

    Under 'installed audio devices" I have 2 AMD HD Audio icons Kdual Radeon 3500 cards bootstrapped), but no xonar. However, in Device Mangler the xonar shows up along with the 2 AMDs. By all,indications the drivers are working. I get no sound and no xonar "equalizer" app opens when I click on the program in start menu.

    What's up?


  7. Adam11 Sep 2015 @ 00:03

    I don't understand the situation of the lack of an impedance setting? What are we supposed to do with high impedance headsets?
    Is there an alternative?

    Can you please clarify?



    • CarvedInside11 Sep 2015 @ 00:34

      Hi. I don't understand which situation are you referring to.


      • Adam11 Sep 2015 @ 02:06

        I understand on the original driver there is the hammer button to be able to change the impedance setting based your headet. I was wondering if there was an equivalent on yours?

        My headset are 150 ohms so I was unsure if this is running at the correct settings.



        • Brandon11 Sep 2015 @ 03:09

          Are you talking about the gain setting for the headphone output? It should be available in all the control panels and Xonarswitch.


          • Adam13 Sep 2015 @ 05:09

            Yes I'm pretty sure its the gain setting. On the original drivers this is under "HP Advance Setting". You get the choice to choose betweel VOIP mode 64ohms.
            Where can I find this setting?? Thanks


            • Giulio13 Sep 2015 @ 09:58

              In XonarSwitch, there is an "Amp" button on the right of the Analog combo box in the Output tab, both in the Profile Editor and the real Time Settings windows.


            • CarvedInside13 Sep 2015 @ 13:31

              The gain setting should be in the same place like when you are using the original drivers.

              Which drivers have you installed? Which card audio panel(ASUS, C-Media, XonarSwitch) are you using? Your OS is?


              • Adam23 Oct 2015 @ 18:07

                Withing XonarSwitch I do no have the AMP button you are talking about. I currently have Asus and XonarSwitch installed. I have the drivers that were released before the Windows10 driver. Currently on Windows 7.

                Any other location I can find it??


  8. FizzyMyNizzy12 Sep 2015 @ 04:28

    Asus finally came out windows 10 drivers for STX - Beta Version


  9. Clayton Jones12 Sep 2015 @ 12:03

    Is there an update to any C-Media drivers for the Xonar DX? I'm using the latest UNI package and occasionally get DPC_WATCHDOG_VIOLATION bsod's in Windows 10. Windows debugger checked it back to cmudaxp.sys which I assume is the C-Media driver. Any help would be appreciated!


  10. Alex12 Sep 2015 @ 15:53

    Hello guys,

    I ran into a problem with my "Xonar D2/PM" and the "UNi Xonar 1816/1822 v1.75a r2" driver. I started using the driver after I switched to Windows 10 and it worked liked a charm. Yesterday I noticed that my microphone of my headset isn't working anymore. It didn't record anything, the headphone sound still worked.
    I unplugged the microphone jack and plugged it in again --> BSOD. The eventlog says:
    "The driver \Driver\cmudaxp failed to load for the device PCI\VEN_13F6&DEV_8788&SUBSYS_82691043&REV_00\7&33280020&0&08004000E7."
    It also saved a dump which I could provide.

    When I try to reinstall the "UNi Xonar 1816/1822 v1.75a r2" driver it says "Please plug-in UNi Xonar Audio device!". But the sound card is plugged in and the "lights" are turned on. In the device manager it shows up as unknown "Multimedia Audio Controller". Installing the card via device manager and the extracted files doesn't work either.

    Any tips on this ?



    • Daniel Cardoso14 Sep 2015 @ 17:13

      I also have this problem but with a Xonar D1. I was able to install the drivers again after doing a system restore but I keep getting BSODs so I disabled the sound card. I get MACHINE_CHECK_EXCEPTION errors and got one triggered by cmudaxp.sys.

      I'm on windows 10 x64 with the latest updates installed.


  11. Spar12 Sep 2015 @ 21:17

    Hello I've a Xonar Essence ST thats worked fine the last few years but after installing a fresh Windows 7 (done it various times before with the same PC/software/hardware) once I install any drivers for the sound card whether they be from Asus or Uni I get the same problem, no audio from anything and videos in IE/Chrome won't load. Anyone encountered this issue? I've found various posts referencing the "hsmgr" processes causing the issue so I've tried disabling them and other things but I still get nothing. Any help would be appreciated.


  12. Fabulist13 Sep 2015 @ 18:41

    Can someone please advise me in terms of sound options?

    I am using a Xonar Essence STX via S/PDIF on the Dolby Digital Live module (the only module that can give me 5.1 output as far as I know).

    On the Lav Audio Decoder, everything is on default, all Output Formats are selected. However, I have disabled “Clipping Protection” and enabled “Normalize Matrix”.

    On PotPlayer, I have the following:

    Audio Renderer: “Build-in WASAPI Audio Renderer” on exclusive mode.
    S/PDIF Renderer: “Build-in WASAPI Audio Renderer” on exclusive mode.
    Speakers: “3/0/2 + LFE – 5.1 Channels” my setup
    Resample: “192000Hz” I guessed higher resample will produce better audio quality?
    Output: PCM
    Speakers: “32-bit (floating point)” I guessed higher values produce better audio quality?
    Resample: “High quality”


    I disabled the “Enable individual volume control” feature, since it degraded sound quality and I don’t need it.
    Equalizer with SuperEQ enabled on Loudness (makes little difference).
    Normalizer enabled on Tomsteady 32-bit.

    However, audio sounds very poor in comparison to my speakers or in comparison to PCM output from PotPlayer, is there something I need to change in my options to improve audio quality for movies? For example, should I change “Resample” to “Same as input” etcetera?

    Thanks in advance.


  13. Erik13 Sep 2015 @ 18:53

    Thank you very, very much for this. My PC was constantly blue-screening for the Xonar drivers and some incompatibility with Reaper, my DAW.
    Now that problem's fixed, but I don't seem to be able to load any 32-bit VSTs anymore. Would you know any thing about that?

    Operating System: Windows 7 Home Premium 64-bit SP1
    CPU: AMD FX-8320
    RAM: 16.0GB Dual-Channel DDR3 @ 577MHz (11-11-11-28)
    Motherboard: ASUSTeK COMPUTER INC. M5A97 R2.0 (Socket 942)
    Graphics: 2047MB NVIDIA GeForce GTX 750 Ti (Gigabyte)
    Audio: ASUS Xonar DG Audio Device

    Thanks again.


    • Erik14 Sep 2015 @ 15:17

      New problem: Now Metal Gear Solid V crashes any time I play it. It didn't do this before I installed these drivers. Is there a connexion and what can I do about it? Thanks.


      • CarvedInside14 Sep 2015 @ 17:48

        Try disabling GX in the Asus Audio Center.


        • Erik14 Sep 2015 @ 18:25

          Thanks for the reply. I had GX disabled for sure, immediately after installing the UNi drivers (because with the Asus drivers it causes problems as well), but when I loaded the Audio Centre just now it was enabled. I suspect that this was because I'd just used Driver Sweeper and driverclean.bat, but I'll try running MGS now and see how it goes. I think there were residual Asus files that these two programmes cleaned, so perhaps that was even the cause of my trouble.

          With Reaper, it seems your installer removes a much-needed bridge plug-in (well, needed for anyone that has 32-bit plug-ins and 64-bit Reaper). I probably need to reïnstall Reaper to get it back, as I can't seem to locate even the name of the plug-in. Just a bit of information so you can have future driver updates not do that. If you need any other information (not sure how familiar you are with Reaper of how pervasive this is with DAWs in general) let me know.

          Should I need to uninstall your drivers, how is that done? and what should I do if the MGS problem persists?



          • CarvedInside16 Sep 2015 @ 21:04

            I don't know what bridge plug-in are you talking about. Don't think it was removed by my installer. You can see for yourself what files are being removed by opening driverclean.bat with notepad. These are only xonar driver files.
            The drivers are removed as all other drivers. From Control Panel-> Programs and Features -> UNi Xonar Audio Driver.


            • Erik17 Sep 2015 @ 17:28

              Thanks. Unless I missed it they're not and never were listed there. But perhaps I did miss it.

              I've done my best to go back to no audio drivers in safe mode, and installed the ones on the Asus disc and so far my system works again. I think the Asus drivers were coming back and causing problems with your ones, so having just the Asus ones in there seems to work.

              I had to install Reaper again to get the plug-in back. I don't see any files in the driverclean.bat that should cause problems with Reaper, but Reaper worked perfectly, then I installed the UNi drivers, and then Reaper didn't have that function anymore. And I do use that programme ever day, so as far as I can tell there had to be a connexion. Perhaps Reaper's plug-in is installed based on your sound card or something, and if you remove the driver it gets confused? Sounds pure strange but it's all I can think of.


        • Erik16 Sep 2015 @ 18:55

          MGSV still crashing constantly and sometimes giving blue screens. I need to know how to remove your drivers completely.


  14. Roman14 Sep 2015 @ 21:23

    Hello for everyone. I've read in top of site about occasional Left or Right speaker imbalance or volume drop issue (this info refers to 1.75b). I have the same problem. There is no link to reports of users. Can anyone share the link please? Thanks in advance!


    • CarvedInside16 Sep 2015 @ 21:18

      Hi. No link to the other reports. The "Left or Right speaker imbalance" that is listed as a possible issue with 1.75b is different from the issue that's been happening for some people regardless of the drivers used. Your issue is restricted to 1.75b or it happens with every driver you've tried?


  15. Kadano15 Sep 2015 @ 12:19

    Hey, thank you so much for providing this! On Windows 10 x64, the newest official drivers (8.1.8-1822, which are for 8.1, none for 10 available) downright refuse to install, while older ones (7.12.8-1794) do install, but are somewhat broken (can’t open the control center to enable digital output).

    For the newest version (1822-v1.75a r2), I’ve had occasional audio stutters in Win10, regardless of sound source (both in Mediamonkey and Opera/Youtube). It happened every three minutes or so for about one second and sounded similar to the repeated sounds of blue screens. With the older ones (1822-v1.72), this has not happened yet, although I’ve only been using them for half an hour so far. If the problem does happen again, I’ll report back here, but for now I think 1.72 is the way to go for Windows 10.


    • arxnova15 Sep 2015 @ 14:27

      you can find official win10 drivers for both the STX and STXII through the official ASUS website support page.


      • Kadano15 Sep 2015 @ 16:10

        Sorry, I forgot to mention that I have the Asus Xonar DG card. For that one, there seem to be no Win10 drivers on the support page.


    • Kadano15 Sep 2015 @ 18:19

      Unfortunately, I still get occasional stutters with 1.72 / Xonar DG / Win10 Pro x64. I think they are a bit less frequent than with 1.75a-r2, but this might be placebo entirely. Every 15 or 20 minutes I think, but so far I haven’t logged them.
