    I have an Asus Xonar DX 7.1, which is the correct driver? Having issues getting audio through this card on Windows 10.

      Normally any UNi Xonar driver should work, but is some rare cases older drivers may work better. Do you have the issues with v1.81a? Try 1.80a, 1.71.1a and 1.80b.
      What kind of issues are you getting? Which Windows 10 version do you have? Did the issues started after some event, maybe a Windows update?

        Just install the card, haven’t got it working yet. It’s recognized in my device manager and i can visually see the audio coming through but no sound. Win10 version 1803.

          Did you just bought the card and installed it? Was the card new or used? Are you using the analog or digital (S/PDIF) connection?

            I think the card was used, bought it off of amazon. And I’m using an analog connection.

              Things you should try:
              1. Make sure your speakers/headphones are currently working and are not the problem. Also check that you’ve connected them to the proper DX output jack.
              2. In ASUS Audio Center or C-Media Panel set the Speakers to 5.1 and Audio channels to 6, connect the speakers to the rear channels output instead and try a speaker test.
              3. If you case has a front panel audio jack, connect the panel to the Xonar DX card. In the ASUS Audio Center or C-Media Panel change the output to Front Panel Audio. Connect the speakers to the case front panel audio and test them.

              If none of those work I think your Xonar DX card is defective.

    I’ve been using UNi drivers forever now and they work fine, however recently I’ve started using things like VoiceMeeter and tried to have my input be bit-perfect using their “hifi cable” (Pretty much offering me a normal audio device to ASIO troughput to VoiceMeeter), as well as the cmasiopPCIX ASIO device offered by the driver, however I’ve encountered the issue that the driver is crashing, very frequently (Multiple times per hour). Playback works fine at 1ms buffering on either end, but at some point the device seems to pretty much to simply freeze, causing VoiceMeeter’s engine to freeze as well and give me the usual “bluescreen soundbuffer loop”. Increasing the buffering does not fix the issue. This problem only happens when going trough the cards ASIO. Using a different ASIO device (Say the monitoring of my microphone), or just kernelstreaming to the card works fine, however I’d love to use ASIO as that lowers the DPC latency by a lot as well as offering less delay and bitperfect quality (Not that I’m an audiophile or anything but free is free right?)

    I have some problems with my STX (first edition). Used to sound fantastic with my Edifier 2.1 speaker set, but over time the sound lost dynamics, got distorted and there are sometimes interfering noises. I tried the Xonar Unified drivers, but it didn’t help. Most likely, it wasn’t a driver issue anyway, because it had worked fantastically before with the official dirvers. I thought it could be due to an old and maybe outworn mainboard, but upgrading my system to new AM4 platform didn’t help as much as I has desired. I then suspected the STX itself to be the culprit and tried to replace it with an STX II. Then I found out this card isn’t compatible with AM4 platforms, as even admitted by ASUS. The B450 chipset isn’t included in ASUS’ official statement about his, but I did run into the reboot issue when trying to install the STX II drivers (original ones as well as the alternatives ones here) on an MSI B450 Gaming Pro Carbon AC. The only remaining thing I could try (apart from setting up an Ittel system, which I don’t want) is getting another STX (first edition). Does anyone know a way to get (a preferably new) one?

    I’ve been using my ASUS Xonar DGX and your drivers for the past two months and everything worked great until yesterday. My mic just stopped working for some reason. When I tried to uninstall your driver my PC crashed all the time, so I reset windows and reinstalled your drivers, but it still doesnt work. My mic works on my onboard soundcard and I unchecked the “Front Mic” in the Asus DGX Audio Center.
    Any ideas why it stopped working and how I can fix this?

      I don’t know if you’ve connected the microphone to the back of the card or to the case front panel.
      Probably it’s a hardware fault, maybe a the card’s microphone jack has become partially unsoldered or some component on the Xonar card is dead. You could try connecting the microphone to the case front panel microphone jack and enable Front panel mic it in the Xonar audio panel if you previously had the microphone connected to the back of the card, if not, do vice versa.

      For the issue which you had with PC crashing each time when uninstalling the drivers, maybe you had v1.81a drivers and you did not follow the specific instructions (playing a audio file when uninstalling).

    Is it possible for you to update these uni drivers to the latest C-Media base driver and eventually audio center (depending on its source)
    Also some accounting for Win10 1809 / new testing and/or development would be appreciated

    After updating to Windows 10 October Update occurred last week I have audio problems. It occurs that the audio on some occasions does not work or better does not feel and I am forced to restart the computer.

      Thank you for the info. Hopefully you can provide the additional information:
      1. As I understand, the sound completely stops after some time right?
      2. When this happens, if you check the Windows Device Manager, what is the status of the Xonar card (working, missing,etc.)?
      3. When this happens, if you right click Windows Volume->Sounds->Playback devices, is the Xonar card set as default playback device (green checkmark)? It’s volume meter does indicate that sounds are playing?
      4. Which audio card do you have?
      5. Which driver versions have you tried?
      6. Do you use analog or digital (S/PDIF) output?
      7. Please mention the complete Windows 10 version and build number.
      8. Please clarify “or better does not feel” statement.
      9. These issues started only after installation of the Windows 10 1809 October Update?

      If you install drivers other than v1.81a, you could use Xonar driver restart tool. On v1.81a drivers you might get a BSOD if you try the tool. If you try it, let me know if this tool fixes the problem without the need to do a system restart.

            I also have a headset who works with a dedicated usb dongle, and when my system have this “no audio” issue, my headset stops working too. I think this issue is more an “windows issue” than sound card drivers.

            • CarvedInside03 Feb 2019 @ 19:48

              From what I can tell, it is either a Windows bug or an audio/video application issue and it may only affect systems with multiple sound cards.
              So far I could not reproduce the issue, but I only used Windows 10 1809 for testing for a couple of hours.
              My current assumption is that when this issue occurs the playback device for the audio/video application is automatically changed from the default playback device (in this case the Xonar card) to something else. This would account for Windows sounds still working as they still use the default device.
              You could check if the default playback device has changed for a specific application with these methods:
              1. Right click on Windows Volume icon->Volume Mixer. It will open with the default playback device selected under Device and this can be changed to show the playback activity under different devices. The volume meter for an application will show activity under the playback device it is currently using.
              2. Type in search “App volume” and press Enter. Here it shows the playback devices for each of the current applications. Even if the Output is set to “Default” for an application that is no longer producing sound, you could manually set it to “Speakers ASUS Xonar..” (if this is the one you are using) and see if sound starts working again.

              If it is a Windows bug, there is also the possibility that the playback device changes internally but this isn’t shown.

      Thank you for the information.
      1. Tell me your complete Windows 10 version and build number.
      2. Are you saying that when changing number of audio channels or chaning output to S/PDIF PCM in the ASUS Audio Center, the ASUS Audio Center exits or crashes?
      3. Have you tried changing the settings with XonarSwitch?

        1. 1809 (OS Build 17763.195)
        2. Tak AsusAudioCenter (32) is close id ended after Audio channel choosing or SPDIF Out selecting.
        3. XonarSwitch after start say “Xonar Speakers are disable”, but I have sound from S/PDIF Output.

        After that, what? Speakers are disabled? Oh yes, for years… But now, I do´t now what is changed in actual Windows, for now I need enabled speakers (otherwise I can now disabled S/PDIF). Strange, but result is, everything is now OK. Thanks for your patient.

        I’m facing the same problem as he did, however, my Speakers are enabled (I use PCM/SPDIF Out).

        I can’t change options using C-media, Asus Xonar or even XonarSwitch. Even the volume can’t be changed through Xonar GUI’s, only through Windows.

        Windows 10 1809 – UNi_Xonar_1821_v1.71.1

        Any suggestions? Is the UNi-Xonar-W10-1825-v1.81a-r2 generating the BSOD while awakening up the computer?

          Try with v1.75a, v1.80a, v1.80b and v1.81a. Normally v1.81 shouldn’t give a BSOD when waking up the computer.

          Upon reading you comment again I realized you mentioned using PCM S/PDIF output. In this case, your problem is not with Windows 10 or the drivers. The PCM S/PDIF can carry only 2 audio channels. For 5.1 SPDIF output you need Dolby Digital Live or DTS Connect encoding and depending on which card do you have you may not have those.

    I tried updating to Windows 10 1809 via the Update Assistant but always got a BSOD.
    In the 3 times I tried it always BSOD and revert to 1803.
    Its a SYSTEM_SERVICE_EXCEPTION on cmudaxp.sys.

    That file seems to be part of the Xonar drivers.
    Maybe I’ll try to uninstall the Xonar drivers before updating.

      Hi. Thank you for the report. It is a false positive. I can confirm that the file you have hasn’t been tampered with and is the same as that in my PC.

      One reason for this detection is that the file is not signed with a digital signature, another one is that the .exe file is actually more like an automated script(AutoIt script) that does a couple of things like changing registry settings, scanning for the audio card and restarting it. Antiviruses these days do not check if the actions of a software where malicious, they just flag anything more or less new and without a signature as a virus.
      Dr. Web detection is ridiculous, for example the file will not modify any startup entries. Probably there where AutoIt scripts that did that and now every application that is based on AutoIt is flagged the same.

      I’ve submitted the sample for whitelisting at BitDefender and will look into sending reports to other major antivirus solutions that detected the file as a virus. Unfortunately, not all antivirus vendors are willing to make an effort and actually analyze the files.

    Is there any way to make .bat for change Audio channels from 2 to 6 channels and reverse? Or for both options separate .bat procedure …?
    … instead of opening C-media panep or Xonar DGX AUdio center to switch between Audio channels.

    1. I cannot find a way to use time correction with my DS or DGX in the Asus or CMedia panels. (Win 7 18.1.1823)
    2. The volume adjustment for the center channel doesn’t work either (tried swapping center/sub).
    My on-board Realtek does all this, and volume adjustments perfectly, but I have other issues with the onboard. Any tips?

      1. You can control the delays following the guide at FAQ Q&A 8.
      Alternatively you could add delays with Equalizer APO.
      2. I have no idea why the volume adjustment would not work. I have tested and it works fine for me. Have you adjusted the volume for center and tested it in the speaker test in C-Media or ASUS panel?

    Hello everyone.

    First I would like to telly you that your UNI drivers basicly saved myself as user of soundcard…currently I am using D2x and previusly I was on DX model. I was always having just problems with every other card and drivers…I could never trully get a 5.1 sound out of them and everthing always sounded distorted to hell. I am using a pretty high ened sound set consisting of Harman Kardon AVR 7000…a 24 kilo beast of a receiver from early 2000 and 5.1 speaker systems from Magnat…big florstanding speakers to be precise. and cervin vega sub. with uni drivers…xonard2x I am getting superb clear sound over toslink to receiver using DTS encoder. Everthing is crisp and clear.

    Lately I got my hands on Phoebus sound card and wanna used it to see how it would perform in games…if it is any better with 3d sound positioning…and it sounds like everthing else without your modded drivers…just muddy, unclear and for most of time eckoing like in a huge hall…and most of times only with 2 speakers….half of options in drivers dont do anthing…other half only makes things worse. it doesnt metter if I am using toslink or headphone jack using my sennheiser HDR175.

    I am now back with D2X but I am trully lost how basicly everthing related to sound cards is utter “shit” pardon my language. Great specs but sound like from 1940s. I wonder if anyone knows how to properly set the phoebus to output clear sound wia toslink in 5.1 using either dolby or dts to my receiver without sounding like mix of trex with helicopter eckoing…on 2 speakers only. Or even better is there something similar like UNI drivers for phoebus out there that makes card usable. I am using windows 10 64 but and Maximus X code motherboard.

    I think many people experienced such problems as I do and I cant imagine going out putting down 200 eurs for card like phoebus and Creatives ZxR only to get hissing unfunctional mess of a sound that makes you afraid of basicly burning down your receiver. All I want is clear sound that simply works.

    • CarvedInside28 Jan 2019 @ 18:09

      Thanks for sharing your experiences with UNi Xonar drivers and how the Phoebus sound card with standard drivers performs.

      3D sound positioning would mostly be enhanced by different driver features or other software that would alter the sound. I don’t think there is enough of a difference between a mid end and a high end sound card to be noticed.

      Regarding you Phoebus card sound quality, there are probably some effects or some sort of software processing applied to the sound. I am not sure if you are familiar with Xonar best audio settings, maybe some tips from there could help.
      You could check the ASUS ROG forums maybe someone shared some info on how to improve the sound of the Phoebus cards.

      If you need a second card and since you are happy with the sound coming from the Xonar D2X with UNi Xonar drivers, if you plan on using digital output (S/PDIF toslink) you could buy a Xonar DSX, as with digital output there is no difference between the cards. By using the soundcard S/PDIF output you are bypassing the soundcard’s DAC and op-amps and use those in the receiver/speakers/headphones instead. Depending on the quality of the DAC and op-amps in those devices, 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 jack connections.

    Using an asus xonar essence STX, I just updated to 1809 and now all sound now has an echo.

    Tried uninstalling / reinstalling 1.81a r2 several times (restarting between each step)
    Tried reverting to 1.80a r3

    Not really sure what to do now. I’d prefer if I didn’t have to ditch the sound card…
