    In September it temporarily had win10 with a Xonar D1 and uni-xonar and got constant crackling, popping.
    Did the driver update that came after that (1.80) fix it it for anyone who had similar issues?


    • Guy12 May 2016 @ 00:47

      yes, i have the same problem, so i read here and tried [UNi Xonar 1822 v1.75a r2] , now i don't hear the hisp's and crackling sounds.
      i use: win10pro 64 - Asus P8P67 motherboard and Asus Xonar D1 pci over optical out 192khz


      • mzso12 May 2016 @ 11:36

        Hmmm. That driver was already available then. And I tried all all recent and a bunch of older drivers. I guess it didn't help me.


  2. my name02 Apr 2016 @ 15:12

    I finally managed to find what was causing the BSOD on my Xonar DG and windows 7, it was "headphones mode" >64 since I have a 250 headphones I pretty much need it
    After weeks of it in "2 speakers mode" I had no BSOD
    Is that a know issue with some workaround/channels/sampling config or just the hardware is broken?


  3. gary04 Apr 2016 @ 21:24

    i installed the 1.80r3 driver (low latency version) on my system which has a auzentech x-meridian 2g.
    now i see two playback devices in win7, the typical 'auzen xmeridian' one which has all the normal properties im familiar with,
    but i also see a new 'cmedia oxygen hd converter' listed as a speaker under playback devices....
    what is this second device, and when/why should i ever use it, since it was installed by 1.80r3?

    Hi, I really love the work here. But I've been getting this high pitch whine issue with my Xonar Essence STX on Windows 10. Is this a know issue and is there any kind of fix/method of preventing it? I have had it 2-3 times in the past few months. Exactly the same as this guy here: https://www.youtube.com/watch?v=KVo9pwQ-W5I


  5. Eros07 Apr 2016 @ 07:49

    I noticed Linux (PCLinuxOS) giving out better sounding audio; richer sound with Xonar DX1. Why is that? Has or can the dev of UNi's drivers check how Linux makes it work?


    • CarvedInside07 Apr 2016 @ 19:41

      I don't know. There is a possibility that what you are hearing is a placebo effect or they just sound different by having slightly different default equalizer settings. I don't know of any objective way to check this claim.
      There is nothing I can do to the Windows Xonar drivers from looking at the those Xonar Linux drivers.


  6. anon08 Apr 2016 @ 12:32

    Hey, why is v1.75a recommended over v1.80a?


  7. alexander08 Apr 2016 @ 14:09

    Skype is crashing on shutdown. I tested many solutions bu t I've this problem since 2 years now :/


  8. Dean20 Apr 2016 @ 03:35

    Quick query- never used to be an issue so a bit perplexed. Am running 1.75a on Windows 10 Pro x64 with a Xonar D2X. Windows is telling me that the device / driver is preventing entering sleep due to a System Required Request. Is this a known issue? Anyone know of a fix?


    • CarvedInside21 Apr 2016 @ 14:23

      But is something actually preventing your system to go to sleep or this is just shown in a report? There shouldn't be any problems with sleep, at least with previous OS's. If you have issues, try installing the drivers again. Are you by any chance using the ASIO output playback?


  9. George22 Apr 2016 @ 01:44

    Hello! Having this strange issue with my Xonar DG (UNi Xonar 1.80a r3, W10, Harman Kardon Soundsticks older model). After a system restart (maybe even waking from sleep, not sure, doesn't happen always), I get no sound from the speakers. Windows volume settings are ok. It will only come back (immediately), if I just touch the volume control on the speaker i.e. the sound comes back the moment I alter the volume from the speakers. This didn't happen with the onboard audio - not sure what can cause this.


    • CarvedInside23 Apr 2016 @ 14:04

      Hi. If I understand correctly you are touching the volume control on the speakers and not the Windows Volume Mixer for the speakers. If that's the case I don't see how this could have anything to do with the Xonar card.
      What I've noticed while using UNi Xonar 1.80a drivers is that many times after waking the computer my speakers weren't getting any sound. Now since I went back to 1.75a drivers I haven't had this issue.


      • George24 Apr 2016 @ 20:51

        Thanks CarvedInside, yes that's correct. My assumption is that perhaps the drivers/card might send a 'wrong' signal on a system restart (or no signal at all) and the speakers automatically enter their mute (or self-protect?) mode? Probably not though. I'll try the recommended 1.75a drivers to see if this still happens.


  10. Martin Plamp24 Apr 2016 @ 20:04

    hello guys 🙂 i am new here and i am using a xonar dx with beyerdynamcis dt779 pro 250ohm (i dont need an headset amp there, loudness is great) ... i am playing csgo and i am wondering which settings u can advice me? in the mom i play 5.1 ingame with dolby headphone (DH-2 setting) and 7.1 virtual speakers, 44.1khz (8 chanels) ... with 1.80a driver ... any thing i can do better? 🙂 ty all 😀


  11. Mayur25 Apr 2016 @ 01:39

    I am facing 2 issues with my DX:
    1.crackling sound with 5.1 analog at 192khz
    2.slowmotion sound with 7.1 at 192 khz

    I have changed my motherboard previously it was working flawlessly. Previously I had different motherboard and processor which was Gigabyte and FX4300 and now have Asus le r2.0 and FX6300.
    After the new motherboard I am facing this issue what should I do?


    • CarvedInside25 Apr 2016 @ 17:30

      I've corrected your post so it can be easily read. If you want for people to help you please make an effort to write and format your text correctly next time. Add "." at the end of the sentences. Write the names with capital letter (Gigabyte instead of gigabyte).

      How old is your Xonar card? If it's manufactured at least 4-5 years ago, you could try updating the cards PLX firmware.
      This firmware fixes more things than those in the log. For downloads and instructions go to Asus Xonar DX download page, select Windows XP, go to Utilities and download PLX firmware update Ver 1.1. It works on Win7 (and probably 8/8.1/10) even if you've selected WinXP.

      You should also look into updating your motherboards BIOS.

      Update: Updated the link.


      • mzso26 Apr 2016 @ 12:39

        Would it be useful updating the firware on a D1? (Although I don't see firmware listed for it.)
        I've always had problems: The left side going silent. Getting white noise after a seek.

        That link is broken. It redirects to the support main page.


        • CarvedInside26 Apr 2016 @ 19:43

          The firmware update is not for Xonar D1. The firmware update is for PCI to PCI-E bridge that PCI-E Xonar cards have.
          Your problems are from something else, maybe a bad card or a motherboard incompatibility.
          Thanks for the heads up regarding the broken link.


  12. Facu1ty27 Apr 2016 @ 22:55

    Hi, I use a Xonar DX on Windows 10. There it is necessary to select the number of source channels. (2 for MP3, 6 for movies etc.) Is it somehow possible to let the soundcard detect this option in an "auto-mode"?

    On an old computer with Windows XP running, the Audio Channels Selection isn't even existing.


    • George28 Apr 2016 @ 01:15

      Check the FAQ, point 9 - your answer is there. No need for "auto-mode".


      • Facu1ty28 Apr 2016 @ 11:21

        When I leave the number of source channels on 6, I cant use Dolby Pro Logic IIx to upmix stereo files back to 5.1. This just appears when I select 2 channels.

        I live in Germany. Unfortunately, Amazon prime for example offers no Dolby Digital 5.1 soundfiles on PC. But nearly every stereo soundfile countains the surround informations I want to hear. So at the moment, I have to choose 6 channels for Blu-Rays and DVDs and 2 channels for "Online-Movies".

        Is it possible to install a Windows XP driver on 7?


        • CarvedInside30 Apr 2016 @ 02:28

          This is how Windows Vista/7/8/10 works. You can't install Windows XP drivers on Windows 7 and it wouldn't work as you would like even if you could.

          You could try XonarSwitch and make separate profiles that you could easily switch between.


        • Dean30 Apr 2016 @ 02:43

          You do have to switch between stereo and surround configs depending on the source you're using. As CarvedInside already suggested XonarSwitch is a great way to deal with this. It's what I use- with 3 profiles: surround, stereo (pl2), and stereo (all ch stereo). It's not hard to set up and works a treat.


        • George03 May 2016 @ 09:33

          Another solution would be to use a good media player like jRiver Media Center for example, that offers high-quality up/downmixing (nothing to envy from Dolby Pro Logic IIx). You will be able to configure it any way you want.

    I just got a DGX and installed your driver in C-Media with GX and got popping/crackling when navigating Windows Explorer (E.G Opening folders and files ) I also tried running C-Media by itself without GX by reinstalling and still no luck.

    It seems to be running fine but I haven't really gone beyond media and general browsing yet.


    • CarvedInside04 May 2016 @ 03:44

      Your OS? UNi Xonar driver version installed?
      If you changed the sample rate to other than 44.1kHz try setting it back to 44.1kHz.


      • Speedster15904 May 2016 @ 04:27

        I'm running Windows 7 Ultimate 64. 1.80a r3

        I did change it from 44.1kHz but even when I reverted still no change. I restarted when I changed settings in the C-Media panel.

        I also found a problem? that took me by surprise... I'm using the Stereo Mix to output to the onboard realtek on my Z77 OCF so I can have both active with the same source at the same time, I then plugged in my microphone at the front panel to check how the driver reacts to it then... massive feedback! The microphone was not set to monitor or Listen to, only Stereo Mix.

        I even disabled the Microphone leaving only Stereo mix in recording devices but that did nothing to remedy the problem, it was still picking up the microphone.


        • CarvedInside05 May 2016 @ 18:28

          For the popping/crackling problem have you by any chance enabled SVN in the ASUS Audio Center? Disable it if you did. Another thing to try is uninstall current drivers and install the 1.75a drivers.
          For the Stereo Mix problem I don't know what to tell you. I'm not familiar ATM with how Stereo Upmix should work. Maybe you should try v1.75a drivers and v1.64 and see if either of them perform differently.


          • Speedster15906 May 2016 @ 15:32

            No I don't. I have Hi-Fi and GX Enabled but nothing else. I'm also bouncing around 32-64 and 64 on the amp since I'm still uncertain.


  14. Mem06 May 2016 @ 19:13

    Hello, I have installed your drivers and after somedays I have problem. When I am playing in CSGO I have error with vac authorization error, It wasn't happending on official asus drivers. My card is Xonar DG.


    • CarvedInside06 May 2016 @ 20:13

      Hello. It's highly unlikely that the drivers have anything to do with VAC errors. You could get the error from recent VAC updates. The only way to make a connection between VAC authorization error and the UNi Xonar drivers that you've installed would be to go back to ASUS Xonar original drivers and see if you still get the errors and after a while install UNi Xonar drivers again.

      Tell me which UNi Xonar driver version and driver panel configuration (normal, low DPC latency,etc.) have you installed. What OS do you have?


      • Mem07 May 2016 @ 01:15

        I was using 1.80a and C-Media Panel. My OS is Windows 7. Right now, after format my PC I am using official drivers from Asus and no problems. I will try install 1.75 version and give you feedback.


        • Danny Damsky10 May 2016 @ 15:07

          This is very interesting. I had VAC errors with Valve for quite a while now, I've actually stopped playing CS:GO because of it, never considered the sound card to be an issue. I also have a Xonar DGX and I use the Uni 1.80a driver.


          • speakn2pabst12 May 2016 @ 23:58

            It's more likely that the common element between your VAC troubles isn't the audio driver but that your both software tinkerers. (who else even searches/finds 3rd party audio drivers?) 🙂 I've had the VAC issues as well but it was due to my installing Process Hacker as a Windows Task Manager replacer. Having it installed even without setting it as a default Ctrl-Shft-Esc replacement for Task Manager was enough to have VAC issues. Check the VAC troubleshoot page for all the other remaining offending software possibilities.


  15. Eugene12 May 2016 @ 00:40

    Hello. I have a d1 card. I tried to use official drivers, uni latest and uni recommended and in every case the microphone boost is to high. how can I reduce it? Maybe some registry parameters. without boost microphone has too low volume, but with boost it's too much noisy


    • CarvedInside13 May 2016 @ 01:57

      Hi. Try lowering the microphone volume while having microphone boost enabled. If that does not work you could connect the microphone to the onboard audio card and see if that is better.
