    hey im using windows 7 premium x64 and using xonar dgx card... when i first install the software it make progress till the end then ask me to insert the card which i already insert it before install the driver then i have to reset my pc to install the driver again and successful. After restart again my pc the software worked well.. Is this normal? Is it have to fail at 1st time then make u reset the pc?


    • CarvedInside08 Mar 2013 @ 16:48

      This is not how it should work but it happens in some circumstances. It could be that the installer or Windows didn't detected the card after it was uninstalled. Ever since I've started the UNi Xonar drivers, I've never encountered this or any other installation problems on Win7 x64 & even Win8 x64, but I know some guys have.
      By reset I think you mean restart.


  2. Arronwy23 Mar 2013 @ 20:28

    I just installed these UNI Drivers but I get no sound. I have the Xonar DG and Windows 7 x64. The normal ASUS drivers work just fine. Any ideas on how to fix this? I can open the C-Media Panel fine but no sound comes out of my headphones.


  3. requiser31 Mar 2013 @ 15:17

    Hi thanks for the driver first of all.

    You say that users should use 2 channels for headphones? But under the information page under channels it says 8 channels for games? Whats the best settings for ingame surround on headphones? 2 channels + dolby headphone?

    Also is it correct that GX button and its function is completelly disabled with these drivers?


    • CarvedInside31 Mar 2013 @ 19:58


      2 channels for headphones for normal usage if you don't plan on emulating surround sound. If you plan that, yes you need to change it to 6 or 8 channels and need to enable Dolby Headphones and/or 7.1 virtual speaker shifter.

      GX button is only disabled if you've selected Low DPC Latency or C-Media Panel in the UNi Xonar driver installer. For "Normal" it will work.


  4. DerAusgewanderte09 Apr 2013 @ 04:26

    hi, must be my stupidity that I can't figure this out. I have the Xonar DX and I read the suggestions. I get good sound if I set channels to 2 and output to 5.1 on my 5.1 system. However, if I use the suggested 6 channels I am not getting any sound from the side/rear speakers. I have played with the Speakers/Configure settings in Windows but that doesn't do anything. Am I missing something? Running Windows 8 64bit.


    • CarvedInside09 Apr 2013 @ 17:20

      You need proper content for 6 channels/5.1 speakers. Meaning a movie or a game that supports 6 channels, and has the right settings configured. What you are doing with 2 Channels/5.1 speakers is playing a 2 channel sound (front L & R) through all 5 speakers, this is also usually known as stereo upmixing. Objectively speaking, stereo upmix is bad in terms of quality and perception of the original stereo sounds.


    • hunterz009 Apr 2013 @ 20:46

      The Windows audio stack in Vista/7/8 does not allow applications to report to the sound drivers how many channels of audio they intend to produce. This means you need to manually adjust the number of input channels in the Xonar configuration application to match your needs.

      Most games will produce 5.1 output, so you will want to set it for 6 input channels while playing those. If you need the Xonar to perform surround decode or upmixing of stereo sources, then you will want to set it for 2 input channels when using those, and then enable Dolby Pro-Logic IIx decoding (or install the drivers in an upmixing-supported configuration?).

      Another option is to use a receiver/speakers that can perform upmixing and/or surround decoding instead of relying on the Xonar to do it, and enable that decoding/upmixing when listening to stereo sources (and disable it when playing games that produce 5.1 natively). This is what I generally do.

      Yet another option is to use software that can upmix/decode stereo sources into 5.1 before it reaches the Xonar driver. Many media player applications (VLC, MPC-HC, etc.) can do this for videos and music.


    • DerAusgewanderte10 Apr 2013 @ 01:27

      thank you for your help CarvedInside and hunterz0. I am trying to play 5.1 sound from a Blu-ray disc. The Bluray has both 5.1 96/24 LPCM and 5.1 DTS HD Master Audio that I tried. Neither work on 6 channels. I do know that the content needs to provide 6 channels, otherwise I'd have to upmix.
      bottomline, From what I understand is that I should be able to hear 5.1 on all 6 speakers if I set the Xonar config to 6 channels with a 5.1 DTS or LPCM Audio disc. Or am I still missing something?
      In the meantime I will try to wipe all Audio drivers and traces from the system and reinstall.
      thank you again for the quick help.


      • CarvedInside10 Apr 2013 @ 20:15

        Yes you should hear from all 6 speakers if content support it there, video player is properly configured , and a particular movie scene has audio for any of the rear speakers for example, you won't always hear sound coming from all speaker.
        Which player do you use? Some players need to manually configuration for 6 channels. Search players documentation for this.
        If you do a speaker test, they all respond properly when you have 6 channels/5.1 speakers?


      • hunterz010 Apr 2013 @ 22:26

        If you're trying to play the 5.1 video over a 6-channel analog audio connection, then you need to check your player config to make sure it's decoding the stream into 6 channels instead of 2.

        If you're trying to stream the raw 5.1 data digitally via SPDIF passthrough, then you need to set 2 channels in and SPDIF PCM out. You will also likely need to mess with your player configuration to tell it that you want to use SPDIF passthrough, or else it will probably just decode to stereo.

        If you want to get the 5.1 audio to your speakers over SPDIF without using passthrough, then you will need to set your player to decode to 6 channels of output, then set the Xonar driver to 6 channels of input and DDL/DTS 5.1 digital output. This is not advised, however, as it means that the original digital stream is being decoded and then re-encoded, likely doubling the number of digital data compression artifacts.


  5. molunbun10 Apr 2013 @ 14:26

    Thanks for the hard work but the installer doesn't work well for my DS on Win7 x64.

    I couldn't hear the 'click' sound from my card during installation and the installer seemed to look for the device indefinitely. In device manager I could see my card with only "Scan for hardware changes"(Which hanged the device manager when clicked) and "Properties" options when right clicked, so I think my card was not properly recognized by the installer. And I couldn't shutdown nor restart my computer without cutting the power. I guess Windows was trying to scan for devices when shutting down. After forcing a shutdown, my card was detected properly and the installer worked. I tried this a few times and this pattern repeated. In an experiment, I extracted the "SoftwareDriver" folder from UNi and overwrite that in the official driver. Worked like a charm.

    1st install: can't detect device->installed .ini drivers only without control panel/software
    2nd install: can detect device->installed properly


    • CarvedInside10 Apr 2013 @ 21:35

      For the record. I've downloaded untouched Win7 with SP1 x64 and Win8 x64 copies from Microsoft and installed them both on my system in order to test the installer for some of issues that people report. It turned out drivers installed without any problems. The only problem I had was if I tried installing with "Digital signature bypass" option but without Test mode enabled, then even without "Digital signature bypass" I couldn't install the drivers, but after a restart everything installed and worked fine. So for now I couldn't reproduce installer issues.

      Yeah, I think you could restart because of "scan for hardware changes" which was stuck. From what I understand from your comment, driver installation worked after restart. I am not sure its safe to say that Asus original drivers would have worked fine in the same circumstances when the UNi Xonar drivers didn't.

      Need some details from you. Did you had Alexas addons installed in the previous drivers? Did you uninstall the previous driver before installing the new one? Please tell me the full name of the official driver you tried. And tell me the state of your Windows (fully updated, SP1 fully updated, etc.)

      Btw I think this discussion its better suited in this page. Just so you know, I will try to move it when I have the proper tools.


      • hunterz010 Apr 2013 @ 22:29

        I've complained many times about these kinds of troubles, but I eventually just gave up and switched Win7 to permanent test signing mode. I don't think I've had problems since, but I'll find out when I try installing the new version you just put up.


      • molunbun11 Apr 2013 @ 09:37

        Alexas addons not installed. Windows 7 SP1 x64 fully updated. Previous driver uninstalled before installing the new one. Official driver is PCI-DS-110512-


  6. DerAusgewanderte11 Apr 2013 @ 00:16

    gentlemen! I really appreciate the time you took to help me. Thank you. it turns out it was my stupidity. Player settings was the key (Cyberlink PowerDVD). After I changed that and changed the Xonar settings to 6 channels I got true 5.1 audio. Listening to Steven Wilson's Bluray of "The Raven that refused to sing" I can actually here different instruments on each channel - amazing. What a difference!
    CarvedInside, the speaker test would correctly play the speaker position on the correct speaker. I should have figured out myself that the player I am using must be set correctly as well.
    hunterz0, thank you for your detailed explanation. I learned something very valuable.
    To both of you - Cheers and thank you!


  7. Neude12 Apr 2013 @ 20:31

    I have WIN 8 with HDAV 1.3, output in Dts and the problem is Winamp won't play the music. But i can see that the music out but no sound is playing.
    I have try to select the right card output in Winamp but nothing happen. However, Bsplayer run correctly. ?????
    Please help me.

    LE: I find the solution, just install Winamp Essentials.


  8. bebetaeyeon14 Apr 2013 @ 01:44

    can you help me..,after installing the latest driver(1.70) my windows system sound is become low, i mean very low,even when all volume panel are set to the max, and when i playing games the sound is very low than usual, but when i play music with asio output in foobar everything is normal, i don't have this problem in 1.64 version, and when i try to get back to 1.64 i can't install the driver, i don't hear "click" sound in my soudncard, so i reinstall my windows n using 1.70 driver, but still, windows system sounds & the sounds when i play games is very low,thnx n sorry for my poor english
    win 7 Sp 1 x64, asus xonar essence stx


    • CarvedInside14 Apr 2013 @ 01:53

      Uninstall 1.70 drivers. Boot Windows in safe mode and try installing 1.64 drivers from there. More details here.


  9. hollowman14 Apr 2013 @ 08:02

    192k Sample Rate via Xonar Control Center sound best to me -- even for relatively low-rez 16/44.1 sources.

    I only have experience with Win 7 and XP, and haven't tried EVERY software tweak/mod, incl. various Foobar plugins. All that said, simply going thru Xonar Control Center and selecting 192k made quite a pos. diff. I mod mostly HW, so opa's, caps, and clocks as well as regs and PSU tweaks. And that 192k ranks right up there with some opa upgrades. The only thing I can guess is that is a form of "upsampling" -- a lot of outboard D/A's and other "high-end" devices add sample-rate-conversion to upsample the datastream going to the DAC.

    “Enable the audio output/playback to 24 bit instead of 16 bit , this might improve audio quality.”
    Perhaps if the orig rate is 24bits (or higher). But selecting 24bit output via Foobar (for orig. 16/44.1 files) degrades audio quality IMO.


    • hollowman14 Apr 2013 @ 23:07

      A bit more to say on the topic...
      The Ayre QB-9 an outboard USB D/A uses two clocks:
      22.5792MHZ for 44.1k/88.2k data, 24.576MHz for 48k/96k
      So, the Xonar's sole 24.576 XO may not be ideal for most audio.
      The 24.576 seems to also be optimized for Firewire.
      See: http://en.wikipedia.org/wiki/Crystal_oscillator_frequencies
      That said, Xonar's manual notes its use of double floating point sample-rate conversion, so "integer division" or "binary division" issues from that 24.576 clock may not be that important.
      But all that said, I just installed the latest n' greatest Uni Xonar 1.70 drivers and played around with the ASIO settings ... and that 192k sample rate in AUS's default Xonar Audio Center still stands out as the best software upgrade I've made.
      It does make some mathematical sense: setting the decoder to a STANDARD "integer division" freq. of the 24.576 clock (i.e., 192k or 96k), and feeding that "clean" math to 1792. But I'm not sure how much of this and/or concomitant up-/oversampling is related to my perceived sonic improvements.


  10. bebeateyeon14 Apr 2013 @ 21:07

    i finally getting back to 1.64 but still..windows system sound is very quiet, i think all sound that played trough windows become very quiet


    • CarvedInside14 Apr 2013 @ 22:38

      Please stop writing your e-mail address in the Name field. Spammers can use it.

      Then its not the drivers, problem is from something else. Check the audio jack connections to the card, speaker connections and such.


  11. larry15 Apr 2013 @ 21:40

    Thanks for the driver but I am getting no sound at all - I have Windows 7...was getting sound before with just minimal drivers but nothing now with the Uni????


    • CarvedInside16 Apr 2013 @ 09:06

      Check the Xonar card in the Device manager.Maybe your card is not detected or drivers not loaded. If so read this topic, I suggest you try to install the card with windows in safe mode.

      Which card do you have?


  12. Bruno Ferreira19 Apr 2013 @ 14:24

    Xonar D2X, Win7 x64, latest 1.70 drivers - C-Media panel version (no GX).

    With the previous version, I had SPDIF output working perfectly. On this version, I get no digital output at all - no matter if it's PCM, DDL, DTS, or at whatever sample rate.

    Also, just like the last version, the C-Media control panel crashes after closing it. Not a big deal since I can restart it.


    • CarvedInside19 Apr 2013 @ 15:21

      Might be a bug or just a localized issue. If you have time, try doing a clean install following the steps from Q&A:1.
      Unfortunately I cannot check this my self. Thanks for reporting this. Let me know if the problem is still there.

      For the C-media Panel crashing. I've tested the drivers with the Cmedia Panel, on multiple Windows, and I must say I have not encountered this. Think this is a localized issue, maybe it will get fixed with the clean driver install.

      LE: Regarding SPDIF can you check and see if you can enable it via ASUS Audio Center instead of C-Media Panel?


  13. Bruno Ferreira19 Apr 2013 @ 21:54

    TLDR: SPDIF problem did not exist, C-Media panel still crashes after closing.

    To "larry" above: check that the default Windows sound device for playback didn't reset itself to some other audio device.

    Full story:

    So I did the clean install, and it... didn't go well. Uninstalled drivers, rebooted, ran the .bat file (as admin), ran DriverFusion and it didn't detect anything. Even ran CCleaner afterwards.

    When installing the drivers anew, the installation bar went _very_ slowly upwards (on a 16GB SSD-enabled system), and it never moved from there. I inspected, and the Kernel process (PID 4) was eating a whole CPU core and doing nothing. I had to kill "CMEAuVist64.exe" to get my system back, and even after that, Windows wouldn't shut down - got stuck at "Shutting down", had to hit the Magic Button.

    After rebooting I did notice that the driver itself somehow did get installed, but the C-Media panel didn't. So I tried installing again, and this time it did go through.

    The SPDIF out problem was simple: Windows had set it itself to use my onboard audio as default device. BUT... this is misleading, because the Xonar still provided analog output, which threw me off (!?!?!?). C-Media panel still crashes (rundll32 error) after closing, but that's not a big deal.

    I should note that I have absolutely zero issues with this box, hardware or software, so if it's a local Windows issue, I can't fathom what.


    • Michael Frikke Madsen22 Apr 2013 @ 22:28

      You'll want to use the xonar analog output in windows sound panel, then go to the driver and turn on SPDIF. If you use the SPDIF passthrough device in windows, you won't be able to get more than stereo. This is due to windows not supporting SPDIF properly. If you want 4, 6 or 8 channels, you'll have to let the drivers handle it.
      The drivers will tell windows that it's an analog device, with X amount of channels (the number you set in the driver). Windows will happily oblige, and tell your software to produce X amount of channels, if possible. The sound then gets to your card, is converted properly to digital output, and is sent out using the optical cable. If you use the passthrough device in windows sound settings, it'll be a stereo device, and your software won't give you more channels to play with.

      I am unsure if this information is actually relevant in your case, but I'm writing just to be sure, as it took a lot of fiddling for me to figure out.

    Xonar DSX, Win 7 32, latest 1.70 drivers - distortion through audio input
    I just installed the 1.70 driver (I did not delete the ASUS drivers) and it fixed several issue with the factory drivers including the USB microphone not working and eliminated lot of distortion and noise feedback with any sound effect, and background noise is gone!

    But with the Stereo Mix audio input, I am getting a lot of distortion. In control panel, playback is set to speakers, level 50, for Recording and th e listen box is checked, My Logitech USB mouse is set to default communications device and everything else is disabled. The stereo mix driver is still showing up as an ASUSTek driver 8.08.1818. Line in, Aux, Microphone, and Wave are disabled. In the DSX Audio Center Wave is the only thing that shows up under recording devices and its volume is set to 50. The playback volumes set to 75, Any suggestions to eliminate the distortion?


    • CarvedInside21 Apr 2013 @ 17:44

      While it probably won't fix the distortion issues you have, I recommend you do a clean driver install like its presented in the FAQ Q&A1, as there might be driver or settings leftovers from previous drivers.

      For your issues with distortion, I don't know, maybe check the to have the usb microphone device "set as default device" and "set as default communications" in Windows Volume Proprieties->Recording tab. I'm not sure why you use Stereo mix , normally you would use that option if you want to record internal sounds , just saying in case you've mis configured.


  15. tennisdoc22 Apr 2013 @ 00:54

    I followed all the instructions in the FAQ and now everything works perfectly including the audio input. Your drivers are awesome and solved all the headaches that I have been working on for several hours to try and fix! Expect to see a donation very shortly.
