    My Auzentech drivers continued to work after upgrading to Win10 but with the Anniversary Update they stopped. So happy the Xonar drivers were able to reanimate my beloved X-Meridien!!!

    Well, I had a couple of EQ presets that are gone with Xonar driver installation. I still have image backups, but I was not able to figure out where exactly the EQ presets are stored. There is neither a file on disk reflecting EQ preset name, nor a registry entry. Also the Xonar settings section (ref "BassBasedBLevel") doesn't seem to contain this information.

    Any clue where I should search for this?


    • CarvedInside24 Sep 2016 @ 20:57

      The file where C-Media Panel EQ settings are stored is "C:\Windows\System\Cmicnfgp.ini" "C:\Windows\Cmicnfgp.ini.imi". But since the EQ presets are missing in current installation it means the old file with your EQ presets was overwritten. Maybe there is a copy of it in the System Restore backup (C:\System Volume Information\).


      • Karsten24 Sep 2016 @ 21:09

        Thanks - but are you sure? I retrieved this file from a full disk image taken before upgrading to Anniversary, and the content of it is just:



        • CarvedInside24 Sep 2016 @ 22:59

          You are correct. It seems at some point C-Media changed the location of the file. Look at "C:\Windows\Cmicnfgp.ini.imi". EQ presets are saved under the [CMI_EQ] group.


  2. Karsten24 Sep 2016 @ 23:24

    Bingo! This file from the backup has the EQ settings I was looking for. But now comes the next question - where to copy them? “C:\Windows\Cmicnfgp.ini.imi” in my current installation of Xonar drivers does not have a [CMI_EQ] group even though I have created two new presets. If I just transfer the contents the [CMI_EQ] group from the backup files to the one in use this doesn't have any effect in the C-media panel. The two presets I created are still there, the old ones can't be seen.


    • CarvedInside24 Sep 2016 @ 23:36

      I don't know why your new Cmicnfgp.ini.imi does not have the [CMI_EQ] group. Try this: exit C-Media Panel, paste the old presets in the Cmicnfgp.ini.imi file, start C-media Panel again (from Start->All Programs->UNi Xonar).
      Which driver version have you installed?


      • Karsten25 Sep 2016 @ 00:59

        I have found the solution – there is another copy of this file under “C:\Users\Karsten\AppData\Local\VirtualStore\Windows\Cmicnfgp.ini.imi” which holds the settings incl. EQ presets.


        • CarvedInside25 Sep 2016 @ 01:06

          I see, glad you found the solution.

            Sorry, probably it was my enthusiasm about the solved problem that made me forget about the rules 😉
            And thank you so much for providing guidance - not only the drivers are great, but also the support!


  3. David23 Oct 2016 @ 00:38

    Hi, thanks for doing this work :). I recently upgraded to a new PC that has Windows 10 installed and wanted my Razer Barracuda AC-1 to work on it if possible. I tried installing the old Barracuda Windows 7 drivers in compatibility mode and in test mode, and it installed without issues, but after rebooting I did not get any sound coming out from it, and I could not even load the application that managed its settings (I'd double-click, but nothing happened). So I tried with the universal Xonar drivers. Uninstalled the Razer drivers, installed the Xonar ones making sure I chose the right card in the list, rebooted...but still nothing I can't hear anything coming out of my speakers or headphones. I am at lost. Is there anything I can try?


    • CarvedInside23 Oct 2016 @ 12:28

      Hi. Go to Device Manager-> “Sound, video …”, does you Razer Barracuda get detected? Double click it and tell us the text under “Device Status” field.


  4. Stefan21 Nov 2016 @ 13:53

    I installed the latest driver (recommends) for my Asus Xonar DX but I had a sound imbalance. My right headphone speaker was louder than my left? This was not the case when I used the official Asus driver.

    I checked "play back devices" but both were set at 76.

    Anyway getting around this?



    • Karsten21 Nov 2016 @ 16:57

      I had a similar problem with running the drivers on my Auzentech and managed to get it removed by setting up in diffferent modes (Normal and/or Low DPC latency). Thereafter, I had proper sound balance in all drivers modes.


    • CarvedInside22 Nov 2016 @ 00:23

      Hello. Might not be related to the drivers. First check speakers connections and do a system restart. If problem persists, install the original drivers again and see if you still have the volume imbalance. If you have, then there is something else wrong. If you don't have the problem, then reinstall the v1.75a UNi Xonar drivers. If you still have the problem, try installing different drivers v1.80a, v1.80b and v1.64. If you still have the problem then reply with the following information your OS and which output you use (analog or digital output).


      • Stefan22 Nov 2016 @ 00:50

        I somehow fixed it.
        This time I fully uninstalled the official drivers from Asus and installed the v1.80 driver.

        It's all working fine and I've got to say...I wasn't expecting this much of a difference. It's amazing compared to the official ones.

        Thank you!


        • CarvedInside22 Nov 2016 @ 03:32

          Glad to hear the problem is gone and that you are happy with the switch to UNi Xonar drivers.


          • robotpants21 Dec 2016 @ 02:10

            I was having a similar issue. The volume was out of balance using UNi Xonar 1816/1822 v1.75a r3. Audio was louder in the Left headphone on my system.
            Uninstalled v1.75a.
            Installed UNi Xonar 1816/1823 v1.80a r3. Sound is in balance between headphones. I haven't tested any other outputs.


  5. tbrx09 Mar 2017 @ 23:34

    Xonar Essence STX II, WIn 7 64 bit, Winamp, ASIO output I cannot control the front panel headphones volume level with anything. I have treid Asus Audio Center, system mixer, Winamp volume, ASIO plugin volume. And the default level is too loud to listen to, it is just as-is. Anything to do here?


    • CarvedInside10 Mar 2017 @ 20:56

      With ASIO output usually you can control the volume only from the audio application. I'm not sure why it's not working in this case, probably something to do with winamp and its ASIO plugin. You should try with foobar2000 player.
      Personally I would recommend using WASAPI output instead of ASIO.


      • tbrx11 Mar 2017 @ 14:16

        I haven't found solution for that, but ever since I plugged the headphones to STX front panel my system not only there wasn't any volume control for front panel anywhere, but my system USB speakers died altogether and nothing helped.

        Found the solution somewhere online, in case it would be needed by anone else after messing with STX front panel:

        First you go to system32/drivers and rename HDAudio.sys to something else. Then you uninstall audio drivers and restart. Then install drivers again and rename HdAudio.sys-somethingelse to HdAudio.sys and at least you reanimate your system USB speakers.

        As for the STX front panel headphones and the audio center application, I'm giving it up, it's obviously crap and brings nothing but troubles. Will continue using USB speakers headphones output. It was better with D2, at least there wasn't any front panel to mess with in the first place 😀


  6. Monkfish08 Sep 2017 @ 18:32

    Is it not possible to use the microphone and optical out at the same time?I have an Asus DGX and I just bought a small DAC as an optical passthrough to fix the interference from my graphics card. It succeeded in doing so but now the mic input is totally dead. Is there nothing I can do about it?


  7. Szymon Koczowski02 Dec 2017 @ 00:29


    A lot of facebook vids and some YT vids are in mono. My speakers have an option to upmix Stereo to 5.1... Which doesn't work on mono 😀
    How do I get mono to stereo conversion?


    • CarvedInside02 Dec 2017 @ 07:37

      Hi. The drivers do not have a mono upmix function. Maybe you could achieve this with Equalizer APO with "Copy channels" filter or some other function. It would probably wise to disable Xonar's stereo upmix.


  8. Luke11 Dec 2017 @ 19:24

    Xonar STX/Windows 10 64-bit/UNi Xonar 1.80a r3.
    Front Panel audio always plays through right channel. How to fix it?
    PS. I have already installed 1.81a r2, but nothing helps.


    • CarvedInside15 Dec 2017 @ 20:21

      Don't think there is anything to be done. It's either the case front panel connection that is broken, you could check for this with the onboard audio card. Or your card has a hardware malfunction for the front panel connection.


      • Luke08 Feb 2018 @ 13:33

        Thank You very much for reply.
        Now I resolved the issue.
        I have broken front panel audio output, so I must repair it.
        Thanks again, and have a good day 🙂


  9. dark12 Dec 2017 @ 04:20

    im useing an asus xonar dx and a modmic connected to it.
    As i get buzzing sound when playing games, i want to lower the microphone amplifier(or boost?) in the settings to be a little bit lower, but there is only an option to enable/disable it and not something like to set it to 50%, which would lower the buzzling sound getting boosted. is there an option or am i missing something? https://puu.sh/yEufc/94e3aec009.jpg


    • CarvedInside15 Dec 2017 @ 20:19

      Hi. Try this: 1.Disable microphone boost. 2.Apply microphone volume increase by 3 dB tweak. See if you still have the buzzing sound and if volume is acceptable.
      Let me know how this works.

      LE: Added link to microphone tweak


      • dark25 Dec 2017 @ 04:21

        Hey, thanks for your comment! I applied the tweak(and checked through regestry if it really applied), but it couldnt change the situation, because im just to quiet without the microphone boost activated, so sadly my friends still get a little bit annoyed by the strange sound when i got high fps in games. Is there really no way to set the mic boost to like 50% instead of just on and off, somewhere in registry or increase the mic volume without boost even more?
        I know its a known problem if you google and some people build emi shields and things like this, but i really want to try and test everything else before.
        When i disable the boost and put the mic like really directly INTO my mouth(to be as loud as with boost turned on) i wont get the buzzling sound, but as soon as i activate the boost its there, but i dont like mics in my mouth 🙁 Hope my english is not to bad. Thanks sir, really appreciate your effort!


        • CarvedInside26 Dec 2017 @ 10:12

          I don't know of a way to control microphone boost level within the Xonar drivers. Instead of using the microphone with the Xonar card, you could try connecting the microphone to the onboard audio card.


  10. Dominic13 Dec 2017 @ 11:01

    Is it possible to use this driver set for a Xonar DX, and 4 pair of stereo speakers with 3.5mm jack?
    This setup is for a 4x stereo speaker pair in 4 rooms, one pair in each room, each pair cabled individually to the computer's location and equiped with a 3.5mm jack.
    I want to use a single computer to play some songs, Internet/streaming radio, and output the sound at the same time to these 4 pair of speaker sets.
    Is it possible to use this driver set to enable 4 of the 3.5mm output connectors to use them as stereo output?


    • CarvedInside15 Dec 2017 @ 22:06

      Hi. There isn't such an option in UNi Xonar driver, with the drivers you could have only 3x stereo pairs.
      For 4x stereo pairs there are multiple ways that you can do that, regardless of driver or sound card type. For example you could do this with foobar2000 player and Matrix Mixer plugin. Once you install the plugin in foobar2000 you can configure it in Preferences->Playback->DSP Manager with these settings. The audio card must be set to 8 channels and 7.1 speakers.

      Update: I've written a guide about this here.


  11. David07 Feb 2018 @ 06:50

    If you please:
    Because of a hard disk failure, a few months ago I had to reinstall my OS and everything else. I run Windows 7 32-bit, and have a Xonar Essence STX card. I had always used ASUS ASIO driver without a problem but after the reinstallation of all software I could not use--terrible stuttering whenever I did anything else on the machine (e.g., opened a browser), though all settings are the same as previously. I tried reinstalling ASUS driver (7_12_8_1794), but did not help (and now suddenly the driver is not even available from ASUS. I have now installed Uni Driver v1.80a r3, but I have the same problem with ASIO playback--not listenable. My interest is in not having to manually switch sample rates for files or streams with different sample rates. As far as I can tell, ASIO4ALL is not doing that, and neither does WASAPI. Can anyone help and/or tell me what's going on?
    Thanks much.


    • CarvedInside08 Feb 2018 @ 04:54

      Things you should try about the ASIO issue:
      1) Check that your system does not have problems with high DPC latency.
      2) Try with Windows UAC disabled. There are cases where ASIO has troubles when running with UAC. To disable this go to Control Panel-> "Change User Account Control settings" and set it to "Never notify" after which restart system.
      3) Change the audio player's CPU priority in Task Manager. Set it to High or Realtime. If you are using foobar2000 as a player check this is not needed.
      4) Try different drivers. Try the 1.80b drivers because they have a different ASIO version.
      5) Change ASIO settings. Try setting the Audio bit-depth to 16bit or 24bit and try different Latency options.

      Let me know if any of these worked.

      I can confirm that WASAPI and ASIO4All do not change the card's sample rate.

      BTW Thank you for the donation.

    Hello! I have Xonar DG soundcard andrecently bought Sony DAC and connected with optical toslink. Working great except one thing, when not playing music or movie, from speakers come some noise like Spdif output is still working. I downloaded spdif keep alive program, and select silence option to solve the issue. Is there any driver tweak to solve this without this program?


    • CarvedInside07 Feb 2018 @ 22:16

      Hello. It sounds to me like the problem might be with the Sony DAC. I don't know any driver tweak that would do that, if I end up finding something I will let you know.


  13. Bernard20 Feb 2018 @ 12:40


    Xonar ST, Win 10 17074 insider build, Dell power edge t20 mobo.

    In both 1.80 and 1.81 my line in is “currently unavailable” in the Windows control panel. Audacity reports it “cannot open audio device” if I try to record. Uninstalls and restarts don’t change anything. I also cannot monitor the input via cmedia or the standard media panel.

    Playback works 100%. Not sure what to try next.


    • CarvedInside21 Feb 2018 @ 00:11

      Hello. Have you tried setting Line-in as default with "Set default" button in Sound window(right click Windows Volume and select Recording Devices)?


  14. Jonas01 Mar 2018 @ 12:32


    I discovered a problem i hoped to get rid of using this uni xonar drivers. Unfortunatly the same issue is popping up. When im playing videogames i have only sounds like jumping, running and a faith enviroment sound. But in the cutscenes and ingame scenes there is no language sound, no music. I remember that i have had the same issue in the past, but i dont know which settings can disolve this now.

    I thought it have to do with "spdif passthrough", but after installing the uni xonar drivers this option is renamed in "digital output".

    On the other hand:
    There are no problems with playing music and videos or the windows sounds.

    Im using a Xonar DX, Logitech 5.1 Soundsystem, Optic Cable, Windows 10 64bit.

    I would be greatful if anyone has an idea for solving my problem.


    • CarvedInside05 Mar 2018 @ 09:23

      Hello. Is this something that happens in multiple games? Which are those games?
      You could try different driver versions and see if either of them solves the problem.

      With S/PDIF Pass-through (or Digital) you are letting the application/game encode it's audio for 5.1 channel S/PDIF output. You would need to set S/PDIF Pass-through as default card in Windows Volume->Playback devices or select it in games options. But if the game does not have DDL, DTS or AC3 encoding then S/PDIF Pass-through won't work.

      Normally you would use the card's drivers to do the encoding if it has this option, in your case the DX has DDL(Dolby Digital Live) encoding which I assume you've already selected in card's audio panel. Another setting you should look at is that you've set the audio channels to 6 channels in cards audio panel and in games preferences.


  15. moogleslam31 Mar 2018 @ 20:27

    Thanks for this wonderful software. I'm using headphones in Windows 10. I've followed your instructions on how to enable 8 channels & dolby headphone. In game (World of Tanks), should I select Headphone or 7.1 Speakers to have the emulated surround sound? Thanks


    • CarvedInside01 Apr 2018 @ 03:29

      You should chose 7.1 Speakers option. Basically, you need the game to generate 7.1 sounds which will be processed and converted by the Xonar driver for 2 channels output.
