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.

    omg omg omg i LOVE YOU SO MUCH!!!!!
    had such a bad day, and get home to replace my on board sound card because one of my 3.5mm jacks broke off INSIDE of the jack….so yeah side+center+sub are shorting…
    and when i get this card it got bad latency issue with asus drivers…
    and this driver has fixed the latency problem i love you.

    I don’t know if anyone will see this message of mine, but here goes.

    I’m trying to install the unified drivers on my Xonar DX. v1.72 beta. First, I did uninstall the standard Asus drivers for my card, then proceeded to install v1.72 beta. However, after rebooting, it’s as if my PC isn’t detecting my sound card whatsoever. I’m running Win 8.1 x64, am I right to assume that the drivers aren’t compatible with Win 8.1 x64 or should I try the older v 1.64 stable release ?

    Please assist, I really want to see if these unified drivers will help with older games such as Fifa 98 where I have crackling audio.


    I managed to get the v1.72 drivers properly installed, I didn’t see the card profile drop down box at the bottom. Once I selected my card there it installed everything correctly, apologies for not seeing that the first time round.

    I still have a few other questions:

    1) The improved low DPC option, if I were to select that, would any type of control panel option be installed as well ?

    At the moment, I selected the normal Asus Media control panel.

    2) Are any low DPC fixes implemented into the driver itself without selecting the low DPC option during setup ?

    3) When right-clicking the Asus media control in the system tray, I see there is an AIO option. I opened that up cause I had no idea what that was and saw to settings. The default values were 16-bit and 10ms. I changed it to 32-bit and 1ms. If I may ask, what does these two settings influence ? Is it a good thing to modify them or not ?

    Report back: With regards to the crackling audio, there is a massive difference in the audio quality compared to the standard Asus drivers (no surprises here). I decided to test out Fifa 98 Road to World Cup, with the standard drivers, lots of audio stutter/crackling. Using the 1.72 unified drivers, the audio problems are basically solved 100% (without the low DPC option selected during setup). I’ve yet to do some more testing but it’s MILES better than what I had.

    If you could provide me with some insight to my questions, I’ll appreciate it big time. I too wish to make a donation at month end.

    Thank you very much for this unified driver, you ROCK !

      1) Both panels are available, but none of them autostart with windows. A major cause of increased DPC latency is running ASUS Audio Center.
      2) No and yes. I haven’t done any changes to the driver itself. The changes I made where to configuration files, for example setting 44.1 sample rate as default compared to 96KHz like on original drivers has a impact on DPC latency.
      3) Those settings are for ASIO playback only. ASIO is a audio output protocol. You normally use Direct Sound and have to explicitly select ASIO as output in audio applications, and then those settings will apply to that ASIO audio playback.
      I suggest you read about recommended audio settings in FAQ: Q&A 9.

      It’s good to know that your not having the problems you had with the original drivers.

      Before you ask any other questions, please read Uni Xonar features page, Uni Xonar FAQ page and the Asus Xonar DX manual.

    Hello !

    I currently have a Xonar DX.

    After reformatting my main HDD for a new SDD, I came to install the drivers over on ASUS’s website and had the “Please plug in your Asus Xonar DX Device” error

    Found that the EEPROM failure was the issue and ran http://www.alsa-project.org/main/index.php/Xonar_EEPROM_Failure

    Great success, the card now installs and furthermore works, I have full sound ; great !

    My problem is that the xonar audio center refuses to start. It just won’t launch ( it flashes on my process tabs then simply vanishes )

    Found someone who went through the same process than me on this forum ; http://www.tomshardware.com/forum/352391-28-please-plug-asus-xonar-device

    He basicly says that he fixed his Software issue ( the hardware is working 100% at this point ) by using your third party program.

    I’ve reformated my SSD and futhermore CLR’d my BIOS and installed your Xonar audio Center to have the same problem.

    This basicly feels like a dead end at this point, any help would be great !

    Hi there. I have an essence STX II soundcard and as usual the ASUS drivers are shite. Will guys ever consider a unified driver for this new card? Thanks,


  5. Robert Hanner    20 Jul 2014 @ 15:13   


    how long will the old Xonar Cards, especially the STX and the new STX II, be supported by the UNi drivers?
    I’m planning to buy a STX and asked the ASUS support how long they support it with drivers. They said they don’t know. I don’t want tu buy a $150 soundcard I can’t use with Windows 9 anymore.



    • CarvedInside    21 Jul 2014 @ 17:05   

      It’s difficult to say. Uni Xonar drivers are modded drivers based on the original drivers. If C-Media, who is does the original drivers for the cards and sends them to partners (Asus, Auzentech, HtOmega), does drop the support for win 9, then there won’t be any Win9 compatible driver from me either.


  6. Squire    22 Jul 2014 @ 15:39   

    so after little while I’m having weird problem, when I turn down the volume within windows the left channels turns down and but right channels stay at full volume
    restarting does nothing, reinstalling the drivers only seems to fix it temporarily , but that’s annoying as its happening often now….
    i have the D1


    • Squire    22 Jul 2014 @ 16:11   

      well seems reinstalling/restarting a few times didn’t fix it, eventually got it working normally again….after like thousand reinstalls of the driver jumping between the original and uni (your) ones
      what caused something like this….?


      • CarvedInside    23 Jul 2014 @ 23:49   

        What OS do you have?

        It could be something wrong with your card. I don’t think I’ve seen anyone else mentioning a issue like yours.


        • Squire    24 Jul 2014 @ 23:36   

          win7 x64,
          its been fine for last two days. Although I haven’t reset my pc for those two days either…but hopefully its fixed…but its defiantly driver related.


        • Squire    24 Jul 2014 @ 23:41   

          thanks for the reply though will keep you updated if it happens again.


        • RossScott    25 Jul 2014 @ 14:24   

          I’ve had this exact same issue also, but on Asus’s default drivers, this is why I sought these out. It happens on Windows 7 64 bit also.


  7. YellowFlash    24 Jul 2014 @ 20:41   

    Hello guys!

    I have D1 soundcard. The sound is great through the speakers, but the Vocal FX tab is not working. I have the latest driver, I could find. I added the Skype.exe to the list, I have GX on etc etc, still nothing. When I call the sound tester in Skype, my voice is still the same.
    The question is, if I install the Uni driver, from here, is there any chance, that my VocalFX effects will work properly?


    • CarvedInside    25 Jul 2014 @ 23:28   

      Don’t know. If audio drivers contained in the latest UNi Xonar driver package are newer than what you have installed so far, then you should try the UNi Xonar drivers.


  8. michal    28 Jul 2014 @ 21:46   

    Thank you so much
    The drivers fixed my BF4 problem!!


  9. James    29 Jul 2014 @ 07:46   

    Hi, I love your work. I want to know if it is just me or whether or not this is a driver issue. If I choose a “line in” profile and run my system listening to music and choose to sleep my windows 8.1 then when I power up the music only sounds for less than a second and then it is silent. I suspect it may be the “uni switch” software. I can get the music back my changing profiles to a non line-in to a line-in profile. My sleep is a sleep to hard-disk with not power to the pc at all during sleep (car setup).
    Also a new feature that I would like would be midi control to the uni switch profiles.
