    So i tried the Dynamic (fluctuating) volume when there are 2 or more active sound sources.
    But the workaround does not seem to be very effecient, there is still some loss in sound in game / music wise...

    Can someone perhaps tell is this a hardware limitation or software issue ?
    Im leaning more towards software since this card is waaaay above the standard onboard sound, which works fine in regards to 2 or more active sources.

    Why is it so difficult to fix this in a driver update? i see the post mentioned "unlikely for C-Media to ever fix" does C-Media need to fix it since it is their audio chipset ?

    Im sure it bothers alot of people and they would love to see a fix, im willing to make a Donation for a driver fix that does not require Windows & in game volume tweaking.
    I know it is small issue, but it is damn frustrating.

    Does anyone know how to run C-Media Audio Panel (CmiCnfgP.cpl) MINIMISED on Windows startup?

    Hi Folks,

    if you like to control your Xonar Audio center EQ-settings from your Android phone/tablet, try my Xonar-EQ app from googles playstore.

    It works fine with my Asus Xonar D2 and D2X and it is completly free.

    regards Sascha

    Is there a way to reduce the echo-ing when using Dolby Headpone and 7.1 Sorround to emulate multichannel on headphones?


  5. Tim27 May 2014 @ 21:13

    first of all i want to thank you for your time and effort for fixing that ASUS Drivers.
    I´ve bought an ASUS XOnar DGX , installed the card and your drivers. The connector for front audio has also been connected to the audiocard. To the green audio connector on the rear is always an 2.1 soundsystem connected. If i want to hear via headphones i plug them into the front audiojack.

    The Front audio is working, but if i unplugg them there is no sound... If i plugg the 2.1 soundsystem into the front it´s also working. Usind my onboard sound the output has been switched automatically. (This feature is also mentioned on the original DGX packaging.

    Pease help!

    Firstly let me say I love the sound improvements over the official drivers!!!
    Im having a problem tho here with my Xonar HDAV1.3 Slim, the reason I got it was to upmix stereo to 5.1 which with your drivers it does perfectly. but when I try to play a Blu-ray with either TMT5 or TMT6 I get bit streamed HD audio but only until I pause or skip the movie, then all sound cuts out and the picture starts to shudder, completely unwatchable.
    Im running windows 8.1
    Any help greatly appreciated!!

    I hope you can help me out, I've become very fustrated by now with this whole sound thing now working..
    Xonar DX -> Win 8.1 64x -> Teufel Decoderstation 3 (Dolby digital/dts) -> SPDIF coaxial connection
    I followed the guides, did the cleanup, installed the latest UNI drivers, but no sound 🙁
    What are the settings for UNI which should work? cause nothing I tried seems to give signs of life..


    • CarvedInside13 Jun 2014 @ 13:39

      Do original drivers work? Or did the card with SPDIF output ever worked? Does analog output work?
      In the audio panel, tick the SPDIF out. Check that you've properly connected the spdif adaptors to your DX. You'll find the informations in the Asus Xonar DX manual.
      Maybe there is also a specific setting that you have to do in the receiver.

    Hello fellow Xonarians, is there a recommended setting on the Audio Center for a 2.0 speaker setup? From sound card to speakers direct, nothing in-between. Thanks in advance.


  9. Leon Schuitemaker07 Jul 2014 @ 03:38

    Hi guys! I'm running into a problem which seems unsolvable! I have a Xonar HDAV1.3 with a H6 daughter board. This is all connected via PCM to a 5.0 setup, so NO subwoofer. The problem I encounter is, I cannot relocate the .1 (subwoofer) channel to the main speakers in any way. I found that in Windows 7 (64 bit) I can set-up the device so the subwoofer is switched off, which should do the trick. But it doesn't, because even though in Windows the subwoofer is switched off, the signal still goes to the subwoofer, not to the fronts. In the Xonar software I can only pick 2.0, 4.0, 5.1 and 7.1 but no 5.0. So, long story short, the Xonar software overrides the Windows settings. Please, any bright ideas?

    What is "AEC"?


  11. Holgicz23 Jul 2014 @ 21:51

    Hello CarvedInside, I have a Xonar D2X and have problems with 7.1 analog surround sound being distorted, but 5.1 works.

    OS: Windows 8.1 Core x64
    Mainboard: MSI Mpower Z97 PCIe 2.0x1 Slot
    Drivers: UNi Xonar 1.72 and 1.64 rev.2 tested with Low DSP Install Option and no Stereo Upmix Option

    Interesting thing is that the following work/work not in C-Media Panel speaker test / mpc-hv (6/8channel_id.wav/.flac):
    All DSP stuff disabled.
    Headphones: 44.1/48/96 work 192 distorted
    2 Speakers: 44.1/48/96 work 192 distorted
    4 Speakers: 44.1/48 work 96 distorted 192 distorted and slow
    6 Speakers: 44.1/48 work 96 distorted and slow and wrong channels 192 distorted and very slow and wrong channels
    7.1 Speakers: 44.1 slight distortion on FL/FR/FC/LFE/SL/SR and more distortion on BL/BR; BL always on BL and BR; BR on BR but quieter
    48 more distortion on all 8 channels ; BL/BR as above
    96 slow on all 8 channels; all distorted but FL/FR and maybe FC; BL/BR as above; channels almost always in wrong order
    192 even more slower on all 8 channels; BL/BR completely distorted; channel mapping almost always wrong

    The channel assignment problems seem to occur more frequently with higher channel number/sample rate.
    mpc-hc's seek sliders stocks/slows with the sound.
    I tried various ASIO latency settings but to no avail.

    Now, the really interesting thing is that with Ubuntu Linux 14.04 x64, everything is working perfectly in analog 7.1 ! (I think 44.1 or 48 kHz)
    With Linux (ALSA / PulseAudio), I have not experienced any distortion, nor channel order mixups or things like that.

    Can this be a PCIe/PCI bridge problem? These slowdowns with more channels/samplerates, could they some bandwidth problem?
    I am not interested in 96/192, but would like to have a working analog 7.1 44.1/48 kHz setup.
    The Onboard Realtek ALC1150 (if enabled) is working perfectly with analog 7.1 on both OSes.


    • CarvedInside25 Jul 2014 @ 23:24

      Just to clarify things for my knowledge. You've tried playing with Media Player Classic Home Cinema? Did you actually use ASIO as audio output in MPC-HC? Have you tried with Direct Sound?
      I have one suggestion, look to see if you can setup WASAPI as audio output in MPC-HC, maybe that would work properly.

      It could be a audio driver problem, but that would be out of my reach to fix. If you want, you can contact ASUS and hope they forward the problem you are describing to C-Media.


  12. Adam20 Aug 2014 @ 20:31

    So i have uninstalled the Asus drivers, updated the BIOS on my Z87 Sabertooth Motherboard, installed the latest Uni Xonar drivers, got stuck at the end with the Uni driver saying 'Please connect Xonar audio device', rebooted. Made Asus Xonar the default output in Windows 7 (64), Ran the Xonar software, and the equalizer shows activity when testing sounds, as well as WMP, however I still get no sound from my headphones from either the front audio panel (where the sound card is hooked into) or the rear lit outut in the back of the sound card itself.


  13. Mike06 Sep 2014 @ 00:17

    I just upgraded (or so I thought) from the D2X to the Essence STX. Why is 5.1 not a selection "Analog Out" and you can not adjust the speaker volume individually from the software anymore....


    • CarvedInside06 Sep 2014 @ 17:16

      Maybe it's because STX does not have 5.1 analog output, you need the Xonar H6 addon card for that. If you have the H6 addon card properly connected try uninstalling the drivers and installing them again. Also try with older versions.


  14. Mike06 Sep 2014 @ 18:28

    Thank you for the info. I started looking for info on the H6 card and am seeing a lot of references to it not working with the stx. Will it work? I would be looking to run digital out to a receiver.

      It seems the H6 only works with ST cards. STX is missing the cable connector to H6.


      • Mike06 Sep 2014 @ 19:08

        ok thank you for the info.


      • Mike06 Sep 2014 @ 19:31

        one more question. Is there a place in the software to adjust each speaker's volume individually?


        • CarvedInside06 Sep 2014 @ 19:45

          You can't adjust the left/right volumes under mixer tab in Asus Audio Center?
          For analog output: Try Windows Volume -> Playback devices -> Speakers (Asus Xonar STX)-> proprieties -> Level Tab-> Balance.


          • Mike06 Sep 2014 @ 19:50

            actually im talking about adjusting each speaker such as the surround left and right. In the d2x software you have that option in the little picture of the speakers where you could move them around and also adjust the volumes.


  15. Xoen20 Sep 2014 @ 16:44

    Using a Xonar Xense, I installed 1822 v1.72, had issues with my Microphone showing unavailable (rear 1/4" jack) in Windows 7 (64-bit) Sound panel. I reinstalled, running a full driver clean as suggested in the FAQ. Now the Microphone is showing available, however there's no Microphone Boost option. I checked and there is an option in Front Mic settings to enable Microphone Boost. Any fix for enabling Mic Boost on the rear microphone input? I will possibly try and drop back to the latest stable release of UNi and see if the same issues persists.


    • CarvedInside20 Sep 2014 @ 20:52

      It's missing from Asus Audio Center -> Mixer -> Recording as well as from Windows Volume-> Recording Devices->Microphone Asus Xonar Proprieties-> Custom?
      Try enabling Microphone Boost from those Front Mic settings and see if it works even though your microphone is connected to rear panel.


      • Xoen21 Sep 2014 @ 19:41

        It's missing from both, yes, only Monitoring is an option in the Windows sound panel. No advanced options are configurable from Xonar Audio Center. I did what you suggested and enabled Microphone Boost on the Front Mic and it seemed to fix the sound levels for the rear Mic. I'll keep an eye on it, because before it was showing both Front Mic and Microphone as "Currently unavailable" and the Mic wasn't working at all, which is why I reinstalled the drivers. Thanks!
