Note about Windows 8.1 RTM compatibility

While drivers up to 1.71 work with Windows 8.1 , they are not fully compatible. C-media Panel is missing some options and its interface is a little bit different (it’s displaying its Win XP interface). I suggest you try XonarSwitch for changing the needed settings.

There might be some problems with WASAPI playback.

    is there a way for me to use analog together with dolby digital live so i can use my better quality speakers in the front?


    • MajorStewie    11 Sep 2014 @ 05:56   

      nvm my better quality speakers use those cheap audio connectors so i can just switch them between the speakers :D

    Hello. I have a slight problem that I’m not sure is possible..

    I’m using a Xonar DX. However, the Xonar DX card i’m using for everything (games, mpc hc, you name it).. but not Mumble.
    On Mumble i’m using my Realtek card on my MSI Z87 G45 Gaming motherboard. Why you may ask :P

    The reason is simple, I wan’t two different outputs at the same time. First of all when i stream, I can configure to not have any sound from Mumble but still
    have everything from the game/music or w/e. Second, I can have loud music without any bother to adjust the volume of Mumble in the Windows control down at the clock.
    All this works perfect.. not realy tho. I use headphones for this, Sennheiser G4ME Zero, so to be able to do this I’m using an splitter (1x 3.5mm female into 2x 3.5mm male)

    By doing this, I’m getting some weird static/buzzing sound mostly when playing games, but can get it when just using Chrome. Moving the mouse over the tabs in Chrome can
    cause this sound, but not loud, just a quiet buzzing. When it’s in the worst state I can manage to get it to go away. I have to move the cable around a little, put them in a special position.
    And all of this is just annoying as hell.

    Any idea how to get rid of this OR is it possible to use Xonar DX for this? Using the two outputs (Backpanel and the Frontpanel) at the same time?
    Or is it only possible to switch between them and use only one of them at once?

    (Side note: Microphone on the Xonar DX sucks, so I’m using the Realtek for that).

    Hi, the driver is much better than the factory one, my only problem is that the line in volume control doesn’t work when recording in ASIO mode, not even in the system mixer (Xonar DS, Audacity). Is there any solution? Sorry for the laymen question.
