    I am using the Asus Xonar Essence STX. Is there a way to change from 2 Speakers to Headphones via a Command line input? This would allow me to change the output with the remote. TIA


    • CarvedInside26 Dec 2012 @ 16:23

      I am afraid not. The only other way you can change the output is with the Front Panel switch standalone application (dl links in the main UNi Xonar page).

    I have a Xonar DGX and in general I don't have any problems with it, however, I can't get X3 Reunion to work without crashing and someone suggested it may be related to a sound card driver issue. I have the latest ASUS drivers installed ( for Win7 64bit), but I would like to try your Unified Drivers v1.64 to see if these might fix problem I am having. My question is this - what is the best procedure for installing the Uni drivers? Do I need to remove the ASUS drivers first? Thanks for any help.


    • CarvedInside29 Dec 2012 @ 22:07

      Remove the Asus drivers first. While you could do a driver clean like its presented here in Q&A 1, this isn't usually needed.


      • LeRoo30 Dec 2012 @ 13:39

        Thanks for the info CarvedInside - I will remove the ASUS drivers using "Uninstall a progam" in control panel. Do I also need to remove the OpenAL drivers? I think these were installed as part of the ASUS driver install.

    Hi I'm a Xonar DS user with Windows 7 64bit and I can't hear my center speaker on my 5.1 system. My center speaker is not broken as I tested it when swapping it with the front left speaker on the control panel of the sub. I've installed the latest driver 07.11.2012. Any ideas?


    • CarvedInside04 Jan 2013 @ 01:26

      Does it work when you test it in Windows or Asus/Cmedia Speaker test?
      You forgning to mention in which case you expect it to work, like in listening to music with stereo upmixed to 5.1 settings or in a game or movie in a media player that's properly configured for 5.1.


      • Fabien Savoret04 Jan 2013 @ 18:26

        No it doesn't work with any of them. I'm expecting it to work with stereo up-mixed to 5.1 with music and true 5.1 with games. I already had it working before I formatted my computer, maybe that caused it to not function properly.

        Thanks for the reply

    Hi. First of all thanks a lot for the great driver, especially for fixing this ugly default icon of the Asus ones.
    I hove on issue I am not getting around which is that WMP 12 on W8 Pro is not playing AVCHD properly with 5.1 Dolby Digital stream when set on SPDIF on pull-through.


    WMP 12 Windows 8 Pro (same for the Video app) playing AVCHD with native Dolby Digital 5.1 slow with no sound when default output device is set to SPDIF pull-through. Setting it back to speaker and using the DDL or DTS works fine.
    VLC media player set to DirectX audio on SPDIF pull-through plays the video absolutely fine and my yamaha Rx-V3900 is showig Dolby Digital properly with great sound.
    Using latest 1.64 with C-Media (no GX) install.

    Forgot to mention: Xonar DX2 on PCI-E.


    • D.04 Jan 2013 @ 01:34

      More information that might be helpful:

      The scenario is, that I have AVCHD (mts. naked W8 install) home video recordings with Dolby Digital streams. I have done the following so far:

      1. WMP, WMC, W8 Pro video app with Passthrough, horrible stuttering no sound
      2. DLed VLC, set the Passthrough, run the Movie -> No issues, Reciever shows dolby stream and its decoded properly with 5.1
      3. Removed the exclusive mode from the passthrough device. Plays nicely, but no Dolby Stream is decoded by the reciever.

      Speaker test works perfect in Windows. I am assuming now that someing in Windows 8 has a hard time decoding AVCHD and while streaming raw data to the optical link in exclusive mode.

      P.S.: Worked fine on my onboard SC (disabled in BIOS, driver uninstalled)


      • CarvedInside05 Jan 2013 @ 01:51

        Hi.Since you say the onboard sound card worked fine in the same situation, then it could be a bug in the Xonar drivers but I can't really help with this. Sorry.


  5. D.07 Jan 2013 @ 20:50

    Hey. Just a short one:

    Is it intended that with a Xonar D2X after an install I have this as my screen even though I selected the C-Media panel in the installer?



    • CarvedInside07 Jan 2013 @ 22:57

      You mean the Asus Audio Center (Panel) instead of Cmedia Panel(looks something like this) or Asus Audio Center for HDAV instead for D2X?
      When installing drivers with C-Media Panel, CMedia Panel is set by default and autostarted , but you can launch Asus Audio Center as well. So if you get Asus Audio Center instead of Cmedia, thats not the intended behavior. Try doing a driver clean like its presented here at QA1.


  6. Vito27 Jan 2013 @ 03:16

    I have 2 xonar (DX, D2X). How to switch between the 2 cards? By default i can control only the DX with Asus audio center and i want to control the D2X. Please help me.


    • CarvedInside27 Jan 2013 @ 12:49

      A method that could work but its not that practical is Disable the DX card in Device Manager and launch Asus Audio center again, this should let you configure the D2X card, then enable the DX again.
      You might also want to try installing Uni Xonar with C-Media panel and launch Asus Audio Center alongside C-media Panel, might be that each panel would took control of a different card.

      Let me know if any of these work.


  7. Vito27 Jan 2013 @ 13:00

    trying to disable the DX its works but the question is why by default the audio manager enable the dx and not the d2x?
    there is the possibility to switch this?
    i have 5.1 connected to the d2x, to the dx is connected a vibration sistem via 3rd part program and i not need to manage with audio Manager. I have the onboard realtek connected also to a vibration system.
    Thank you for the answers


    • CarvedInside27 Jan 2013 @ 13:08

      It has to do with how the Panels scan for existing cards, the first card detected get to be controlled. <del datetime="2013-01-27T11:03:16+00:00">At this time I don't know of any way to change scan priorities or make D2X the default one.</del> In volume->playback devices try setting your Xonar D2X as default.


  8. Vito27 Jan 2013 @ 13:10

    but if i install the c-media pannel, it works together my Audio Realtek HD program?


    • CarvedInside27 Jan 2013 @ 13:12

      Don't know what you are saying here. Cmedia Panel is just like Asus Audio Center, don't see what this has to do with Realtek panel(?).


  9. Vito27 Jan 2013 @ 13:14

    Ok i'm trying, i let you know


  10. Vito27 Jan 2013 @ 13:41

    Don't works, c-media panel and Audio center together manage only the dx 🙁


    • CarvedInside27 Jan 2013 @ 13:47

      Try this , go to Volume->playback devices try setting your Xonar D2X as default. And exit the panel(s) from system tray and start it again.


  11. Vito27 Jan 2013 @ 13:53

    Don't works, the program see as default the dx instead the d2x 🙁


  12. UAsk01 Feb 2013 @ 15:49

    I have 2.1 audio system, connected in xonar dx two 3,5 mini-jack: front and sub, in UNi setup as analog output 2.0, but FlexBass dont work(( How get work 2.1 audio system?


    • CarvedInside01 Feb 2013 @ 17:00

      True 2.1 (as 2x 3.5 jacks) configurations aren't supported in the Asus/Cmedia drivers and so they are not in the UNi Xonar drivers. So its not a problem with Uni Xonar drivers.

      Now, I came up with some guidelines that might help you achieve 2.1, in this arhive you will have some pictures that will show you what to select , but first you need to install the uni xonar drivers with "Re-enable stereo upmix option" and connect the subwoofer jack to the center/subwoofer jack on the card.
      Let me know if this helped.


  13. david19 Feb 2013 @ 01:14

    I'm trying to install the new beta 1.64 drivers on windows 7 64bit with a xonar essence STX card. I've done all the cleanup instructions and i rebooted after each one.

    I'm trying to install with the C-media panel option enabled. Everytime it comes to the driver install the progress bar just creeps along at a very consistent, very slow pace until it hits the end. The first time it just sat there and did nothing for a long time and I had to end the process. I re-cleaned everything and tried again and this time a little bit after it hit the end it prompted me "please plug in xonar uni device".

    I had the crappy asus drivers successfully installed and working for about a year, so I know the thing is plugged in and working. Any advice?


  14. CarvedInside19 Feb 2013 @ 16:45

    Sometimes this kind of issues appear. Here is a page where there are presented 2 possible solutions for these kind of issues. Let me know if those helped or not.


  15. Erik Högberg20 Feb 2013 @ 14:30

    I have ALOT of problems with theese drivers. They include the 3D being switched around, so left is right and right is left, a low static sound when i put it on headphones, i cant get the same amount of sound from all the outputs (im stuck with either 5.1 or no sound output at all, which stinks), most of the windows sounds, and sounds in other games are cut in half, and any flashplayer sounds are three times as loud from what they used to be.


    • CarvedInside20 Feb 2013 @ 18:34

      These drivers DON'T HAVE MORE ISSUES than Asus ones, the static noise you've already confirmed you had it with Asus original drivers, and that issue is not driver related. Now for the rest of the issues , either they are fixable with a driver reinstall (uninstall and install again) or you have those issues with the original drivers as well. Why don't you mention your card , OS and which driver version did you installed?


      • Erik Högberg21 Feb 2013 @ 02:09

        I would reinstall, but there is no uninstall option in the setup. Nor is there one in ccleaner, or windows programs and functions :/

        OS: Windows 7 Professional 64-bit
        Card: Asus Xonar DGX 5.1
        Drivers: UNi Xonar 1813 v1.63 beta


        • CarvedInside21 Feb 2013 @ 11:39

          Check in Control Panel->Programs and Features -> UNi Xonar Audio.

          If its not there, install the drivers and see if you see it there then.
