    Thank you for developing these drivers, I have been having ongoing BSoD issues relating to the OEM drivers, even with there most recent release. The low latency modification has greatly improved my sound quality and every thing works without having to use the useless Xonar Control Centre. I have also not had any pops or sound freezes which is a relief after spending big bucks on a Xonar STX Refrence Class sound card. I am hugely dissapointed with ASUS for not providing the support expected for such a high end product. So thank god there are those out there who take the time to fix there shortcomings. Many thanks and keep up the good work!!!!!!!

    Thanks for your effort and expertise here. Very much appreciated.

    I have a problem with the ASUS Xonar STX card stopping the pc (windows 8) from sleeping. I have used the powercfg.exe configuration tool to determine that the Xonar is causing the problem and to override the Xonar request to keep the pc on, to no avail. Is there some info you have on this issue that might help?
    many thanks

      You might want to try installing drivers with Low DPC Latency panel configuration and check then without starting ASUS or C-media Panel.


  3. Saurav Srivastava15 Oct 2013 @ 19:23

    These drivers need an update for Windows 8.1. I tried installing with unsigned driver check disabled. It installed but the sound card failed to start and was showing an exclamation mark in device manager.


    • CarvedInside18 Oct 2013 @ 12:30

      There are multiple ways to install the drivers, what you have there might not be from Win 8.1 compatibility. Please check the possible solutions from here.
      Tell me your card.

    I've not yet tried your drivers and have a question already 🙂

    I'm trying to use the Xonar D2X as a subwoofer filter and preamp, running off the SPDIF input (as opposed to internal audio streams). I guess my question is whether the bass management is placed before the output or before the speaker output. And whether this is indeed possible given the hardware architecture of the card. The OEM drivers seem to place bass management and all other features before the mixer and route all physical inputs after mixer. I notice that all my analog stereo pairs seem to play back the input S/PDIF signal in stereo when monitoring is enabled (Sub and center operate as L/R pair, both playing the full signal).

    The OEM drivers allow me no control over the physical inputs. they also, annoyingly, upmix all internal stereo streams to 5.1 and there is no way to disable this (though I do not plan to use it this way).


    • CarvedInside23 Oct 2013 @ 21:02

      Hi. These drivers are modded drivers based on the original drivers so they will not work differently in regards to bass management and so on.


      • sangram24 Oct 2013 @ 13:36

        Thanks for the reply and I did work out how to get this to operate somewhat correctly, albeit with a latency of over 150mS. Apparently the problem is not the driver, as the routing is handled by windows and not the Asus driver at all. I suspect your driver will also have to surrender to windows! Will report back after I try them out, thanks so much!

    I tried installing regular asus panel, cmedia, cmedia with gx and dpc latency. They all have the same problem for me. When i listen to music and someone messages me on skype without the chat window highlighted, it stops my music for a split second. I'm using an asus dx btw. Does anyone know how to fix this?


  6. Neto-Zeme31 Oct 2013 @ 16:16

    hey! first: thanks for that great tool 🙂

    now I have a problem. I'm using a Xonar D2. (no PCI-e!)
    In windows 7 x64 your drivers worked perfectly. I installed win 8.1 yesterday and now it seems they won't work correctly. More exact the c-media panel. first the look changed.
    It looked like this in win 7: http://www.hardwareheaven.com/reviewimages/corsair-hs1/corsair-hs1_panel1.jpg
    now it looks like this in win 8.1 : http://images.tweaktown.com/content/1/1/1155_3.jpg (patch to panel 1.62 didn't work)
    It's the same installation in both. (1.71)
    and second the c-media-panel doesn't work properly. When I am in the mixing console, the volume knob and every other button there has no effect. But flexbass works, even does every other function.
    The ASUS Panel works without any problems.
    I had some sound issues before, that, when I started skyrim for example, the music was like in a can, switched out, started ASUS panel and it sounded like it should.
    Windows settings are correct too.
    Reinstalling didn't fix it.

    Do you have an idea? btw: in my device manager there is an entry for uninstalled hardware: (translated from german to english, maybe it's not correct): "PCI-communications controller (simple)" with an yellow exlamation mark.

    thanks for your work again. 🙂


    • CarvedInside01 Nov 2013 @ 10:35

      This is normal with current drivers. Please read "Note about Windows 8.1 RTM compatibility" from the main UNi Xonar page.

      The entry in Device Manger is a motherboard chipset component. Try installing chipset drivers.


  7. Hellgrace03 Nov 2013 @ 23:55

    You deserve a big "thank you" for working on these drivers. I'm running Low DPC with a Xonar DGX and so far everything is perfect!


  8. fractalsauce10 Nov 2013 @ 17:58

    Okay I've been looking everywhere to try and fix this but the solution doesn't seem to exist. I have an ASUS Xonar DG that I use for my PC. I listen to music everyday as well as play guitar along to my favorite bands. I know that with every other sound card I have there is usually an option for "Loudness Equalization" under the Enhancements tab in the Speaker properties window. This tab is completely non-existent for me and thus every song is heavily compressed and sounds like crap. It's starting to piss me off as I just bought this soundcard. Do they really think heavy compression sounds better than dynamic music? At least keep the option to turn it off. Anyways if anyone knows how to fix this, I would greatly appreciate it. Thank you.


  9. zwu17 Nov 2013 @ 16:19

    hi, thanks for the driver - i just got my asus xonar dsx and installed your driver (1.71 cmedia setup) straight away.
    i have a tritton 720+ 7.1 headset with decoderbox plugged in through spdif, win 8.1, what settings are recommended?

    i have set to 8 channels out and digital audio 44.1 khz - disabled dts and everything. is this the best choice or should i set output to headset?

    i do mainly gaming and some music and teamspeak.

    i also noticed - when i plugin my 2.1 sound in frontpanel i get more fps while gaming - than with spdif.



    • CarvedInside18 Nov 2013 @ 14:24

      "i have set to 8 channels out and digital audio 44.1 khz – disabled dts and everything. is this the best choice or should i set output to headset?" - I think so.
      8 channels requires more processing to be done by the CPU compared to 2 channels, so a slight decrease of FPS in CPU intensive games is to be expected.


  10. Gero18 Nov 2013 @ 15:21

    I have a Asus Essence STX and a pair of K701's .... do they count as 2 speakers and should I set the channels to 2 or 8 ? It's about getting positional accuracy in Battlefield 4. And what should I select in BF4 audio menu, Hi-Fi or Home Cinema?
    Would much appreciate a good explanation, I can't find any reliable sources for this and everyone keeps telling me slightly different things.


    • CarvedInside18 Nov 2013 @ 19:56

      They count as 2 speakers, and normally you should set 2 channels. Now games these days usually have good sound positioning while using 2speakers/2channels , but in some cases you could achieve better sound positioning by simulating 8 channels in a 2 speaker environment (you will also need to enable 7.1 virtual speaker shifter). I personally don't know how good the positioning is BF4 in 2speakers/2channels.
      Regarding BF4 audio settings. If you use 2channels/2speakers then definitely use Hi-Fi. On a simulated 8 channels or a real 5.1/7.1 audio system it would be probably better to use the Home Cinema. These things should be covered in the BF4 manual.


  11. Gero27 Nov 2013 @ 15:00

    hey thanks for getting back.
    What exactly would be the difference between using the setting Headphones vs Hi-Fi ? Unfortunately there is no BF4 manual, there is in fact no information on the net about BF4's audio engine.
    I guess it's up to me to find out if the HRTF of my soundcard is better than the in-game one?

    Btw, are the Unified Drivers only there to improve the control of the options, or does the sounds get better too? Thanks


    • CarvedInside27 Nov 2013 @ 15:41

      Please use reply button (top right of a comment) when responding to a discussion/comment.

      I really can't help you more with the differences or which options you should pick in BF4.

      Unified Xonar drivers are not actually about improved control options. Please read the UNi Xonar features. A significant number of people reported that installing UNi Xonar drivers with Low DPC Latency or C-Media Panel configuration they've noticed improved sound quality over the original drivers.


      • Gero27 Nov 2013 @ 16:38

        hey sure no problem thanks for the help so far! great, I see there's more stuff to read about in the links at the bottom of the features page. btw do you know what Lui's plug-in does?


      • Gero28 Nov 2013 @ 11:08

        oh sorry for the double post, but you seem to know your stuff and I can't figure out one question, which no one in the 4 forums I am in can answer.
        Some people swear on using stereo in video games. Afaik pure stereo only delivers L/R audio information. But these people swear they can hear enemies in front / behind them and even above and below. But can't explain why they can hear that.
        Am I missing something? And I mean stereo without any surround information downmixed into the two channels and no HRTF.


        • CarvedInside28 Nov 2013 @ 15:43

          I don't know how to explain this. When you watch a movie, and while not looking at the screen and something drops from to the floor, you would know that something dropped to the floor because of the sound and you can tell if it was from the front table or somewhere in the back. You can produce depth and space positioning with 2 channels. As I stated in my first reply, games can have very good positioning within 2 channels only, it just depends on whether the maker had the interest to do that.


          • rizlo30 Nov 2013 @ 21:13

            i have an asus dx and i am experiencing a weird problem.the front panel gives me more bass than the rear output.that's with the asus driver.with 1.71 low-latency i have no bass at all when i connect my headphones in the rear and normal when i connect them to the front(hd audio).24bit 44100hz 2 channel,no full range speakers,gx disabled and the other settings at stock.maybe i have messed up the settings while i used 1.71 and a new install fixed that.but the thing that i don'get is why this difference in bass volume between front and rear output.my headphones are 32ΩΜ and i know there is a built in amplifier in the rear.also vlc seems to give a little more bass volume than mpc-hc while i play video clips.


            • CarvedInside02 Dec 2013 @ 00:15

              Please don't reply to comments in a different discussion.

              Both front panel and rear should sound exactly the same. Make sure the headphone jack fully enters the front panel input jack. Try with different drivers (like 1.64). If problem persist it could very well be a hardware defect on your card.


  12. Bruno+Ferreira02 Dec 2013 @ 00:37

    Have you ensured that you're not doing subwoofer bass redirection, or that you leave your speaker setup to 5.1 instead of headphones? Because that sounds like either issue.


  13. rizlo02 Dec 2013 @ 21:05

    reinstalling the 1.71 solved the problem.so both front and rear output don't make a difference in sound quality?


  14. Narratorway03 Dec 2013 @ 23:49

    Xonar DX
    Win7 SP1 w/ Auto Updates

    Install creates prompt "Please plug-in UNi Xonar Audio device!" and only offers to retry - which fails - or cancel. Confirmed DX is plugged in, including additional power plug and device shows lights on. Uninstalled, deleted drivers and tried again. Issue remains.


    • CarvedInside04 Dec 2013 @ 00:14

      You had a previous set of drivers installed before checking UNi Xonar?
      Please check this page. I suggest you start with "Possible Solution 2" and if that fails try Possible solution 1. Let me know if you still have the issue.


  15. Sergey05 Dec 2013 @ 07:13

    Hello all,
    I have a question. Is it possible to make the card (Xonar DG) autodetect what output is connected and switch automatically? Exactly like a Realtek chip did (until it died, that's why I bought DG).
    Thank you for the improved drivers anyway, there should be choice!
