    Hey, thx for the driver. Im using a Xonar DG 5.1 on Win 10.

    My problem is that only the Sound works. Cant use the Mic, it doesnt record anything.

    Ps: Im on the UNi Xonar 1816/1822 v1.75a r2


    • Flo07 Aug 2015 @ 06:14

      Exact same problem for me. After upgrading to Windows 10 Pro and using Uni Xonar 17.5a on my Xonar DG my microphone does not respond to any input, despite working on other sound cards and OS just fine.


  2. Pierre03 Aug 2015 @ 05:01

    I have a Asus Xonar D2X, everytime I open applications and games, I get crackling audio over my sound system. I am using the 1.75b driver with Windows 10, worked fine with Windows 8.1 though. 🙂


    • mzso03 Aug 2015 @ 23:43

      I'm in the same shoes, only with a D1:

      Upgrading LAN driver and clean installing geforce helped, but not fixed the issue. Do you also happen to have an older PC?


    • Leiska04 Aug 2015 @ 22:38

      I have the same issue, though I upgraded from Win 7. It's inconsistent, though. Most of the time there is little to no popping, but once it got so bad I had to mute my game because it was destroying my ears.


    • mzso05 Aug 2015 @ 10:50

      What sort of hardware you guys have outside the soundcard? Two of us have an Nvidia Card, but two people is not really representative of anything...
      Also can you run LatencyMon ( http://www.resplendence.com/download/LatencyMon.exe ) too see if your results are anything similar to what I have?

      (I already provided mine. Unfortunately no-one could/did tell me where exactly the problem lies)


    • Kenley09 Aug 2015 @ 23:09

      Try installing the drivers using a Low DPC option. That fixed all the issues I was having.


      • Pierre17 Aug 2015 @ 18:28

        Actually, this didn't work for me at all, I have tried the C-Media Panel installation, Low DPC, everything. I still have the problem; at first, I too thought it to be a DPC latency issue, however, that is not the case, mine is between 50-70, as I understand it, that is very good.

        My computer specs are:

        CPU: Intel 4760k
        Motherboard: MSI Z87-GD65 Gaming
        Graphics Card: MSI GTX760
        Sound Card: ASUS Xonar D2X

        I have tried everything, changing between 16-bit / 24-bit and different KHz ranges, nothing, nada. Like I said, this only started as I upgraded to Windows 10 with the UNi Xonar 1822 v1.75a r2 installed. (Same driver I used with Windows 7 and 8.1, which worked perfectly) I even tried the previous 1.72 driver with all the options, still nothing.


  3. Emilio03 Aug 2015 @ 13:49

    Freshly installed Windows 10 Ultimate RTM + Latest Uni Xonars on a Xonar D1 (normal install, no low latency or anything) and everything works like a charm, youtube too 🙂
    Downside of the thing is that I'm using an external amp so I can speak only for the digital output but not for the normal ones, sorry 🙂


  4. Tharanei04 Aug 2015 @ 19:03

    For those who have the mic problem :

    Go to the Asus control panel, and check if the mic is not muted.

    It happen to me each time i should reinstal it.


    • CarvedInside05 Aug 2015 @ 00:28

      Can you tell me your card, OS and last drivers you tried having this problem.


      • Stefan07 Aug 2015 @ 03:02

        Hey! I own the Asus xonar dgx and am running a hyper x cloud on it. My microphone does not work after upgrading to windows 10. I have tried all I can think of. Flushing drivers, trying realteks drivers, asus own (can't even install em' haha). But skype will not recognize any sound coming through it. Can I have plugged the cables wrong? Or is just the drivers? Would be very thankful if anyone could solve it. What tharanei suggested has worked earlier but on win 8.1 pro. Does not work here though whatever I try. Any helpful response is appreciated.


    • Josua03 Sep 2015 @ 21:34

      About the mic problem, in windows properties i had to uncheck "Front mic" into personnalise tab to get it working. Works like a charm now 🙂

      Hope this will help.


  5. Matt05 Aug 2015 @ 09:47

    I don't seem to be able to get any sound through the Asus card I've uninstalled the realtek audio drivers. Set Asus to default, and am currently using the 1.UNi Xonar 1816/1822 v1.75a r2 driver. Any ideas?


    • CarvedInside05 Aug 2015 @ 15:31

      What OS do you have? Which Xonar card? If you go to Device Manager is the card recognized and does it show it is working properly (under device status)?


  6. Kanuki06 Aug 2015 @ 11:56

    Does anyone here know whether HDAV1.3 H6 Card is the same with STX II H6 card or not?

    Is it worth upgrading from HDAV1.3 Deluxe to STX II 7.1?


  7. Daniel06 Aug 2015 @ 16:28

    I have an Asus D2X card on an MSI motherboard, running Win7Pro64. The Asus S/PDIF output connects to an external surround receiver with in-built DTS/DD decoders. I'm trying to get DTS pass-through (from DTS-encoded FLAC music files), but all I get is silence. I started with the default Asus-supplied driver, and now have installed this UNi Xonar 1816/1822 v1.75a r2 driver, but they both do the same thing...

    If I go into the Windows Control Panel/Sounds, and Properties for the card (set for 'Digital Output'), I can select DTS and Test, and the receiver displays 'DTS' and correctly plays the test sounds through my four speakers. But if I play a DTS audio track (and I've tried several different players), I just get silence from the receiver (and no 'DTS' indication). Stereo tracks play OK through the S/PDIF connection.

    Can anyone help me get DTS pass-through working?

    Thanks, Daniel


  8. John07 Aug 2015 @ 02:24

    Thanks so much got windows 10 today and no audio center so no choice between headphones and speakers. Followed this and turned on test mode. Perfect thanks so much!


  9. Andrew07 Aug 2015 @ 06:35

    Ive upgraded from windows7ult to windows10pro, never touched the xonar drivers. Everything works just fine. Only 'issue' is an audible 'pop' when firing up archeage. Other then that, 100%. Xonar Essence STX here.

    I see that the STXII has windows10 drivers out. Maybe the STX will soon?!


    • CarvedInside07 Aug 2015 @ 17:56

      The Windows 10 drivers for STXII are the same as that I've used in 1.75b drivers and aren't actually new.


  10. Danny Damsky07 Aug 2015 @ 20:18

    Should I stick to 1.75a or should I update to 1.75b? I got a Xonar DGX, I'm not a huge fan of fiddling with windows controls so I don't feel like enabling test mode, which is why I"m asking if it's worth the hassle.


  11. Ron07 Aug 2015 @ 23:50

    "About Chrome shutter issues on sites like YouTube. (7 Aug 2015)

    "After some testing and some reading it seems that the shuttering issues are not related to the UNi Xonar drivers. I’ve got the same behavior with Realtek’s onboard audio and from what it looked liked. My guess the issue is caused either by Windows 10 resource management or Chrome."

    Regrettably, this has not been my experience. I was having the audio stuttering problem in YouTube using Chrome in Windows 10 with the Uni Xonar drivers, and my sound settings were at 24-bit/192KHz. The weird aspect of the problem, at least for me, is that other video sites (Vevo, for example) ran fine in Chrome. Videos with the Vevo label that were posted on YouTube, however, suffered from the audio problem, too. The only way I could make the problem disappear is to lower my sound quality settings to 44.1KHz.

    I tried an experiment and switched my hardware to the Realtek onboard sound on my motherboard, and the problem disappeared, even with the setting at 24-bit/192Khz. Most of the people that I read about who were experiencing the problem in Windows 10 were using Uni Xonar drivers and ASUS sound cards, as I was.

    So it's a combination of Uni Xonar drivers, Chrome and Windows 10 that seems to be having problems properly running YouTube videos at any setting other than 44.1 KHz. You may be right that it is a Chrome problem, since all other video sound in Chrome, at least in most instances, works fine with the Uni Xonar drivers, and YouTube functions properly with those drivers when loaded on other browsers. It's confusing, but at least for me, the problem went away entirely when I switched to the Realtek ALC892 on my motherboard.


    • mzso08 Aug 2015 @ 16:28

      I highly doubt Chrome has anything to do with causing this. I and multiple others experienced crackling, stuttering, well anywhere where sound played.
      You'd probably notice at least clicking/crackling when you listen to music in your media player.


      • Ron08 Aug 2015 @ 16:54

        As they say in the commercials, "Your mileage may vary"! I was careful to note that the experience I had was my own, and that it might not be the same with others. I did extensive troubleshooting, and the issues I had with YouTube videos playing choppy, crackling and slow audio were exclusive to Chrome, and the only way they disappeared is when I set the sound quality to its default setting of 44.1KHz. I was careful to use the exact same YouTube video when testing between Chrome, Internet Explorer, and Microsoft Edge, and although my ears are old, the difference in sound between the three browsers at 192KHz was very apparent. Most notably, the sound from the video in YouTube under Chrome actually slowed down the song by nearly a full beat.

        I don't presume it's exclusively a Chrome problem, because YouTube videos in Chrome work just fine in Windows 10 with the Realtek onboard sound and drivers, even at 192KHz. I just know those same conditions did not apply for me when using the Uni Xonar drivers unless I lowered the sound quality. I also know that other non YouTube videos worked in Chrome with the Uni Xonar drivers and the higher sound quality settings, so maybe there's some incompatibility with the Uni Xonar drivers at their highest settings and the way YouTube videos are encoded.

        Isn't troubleshooting fun?

        FWIW, there's an entire thread in the Google Chrome help forum on this very topic, and it's pretty active, so I swear I'm not making this up! 🙂


  12. Aidan35708 Aug 2015 @ 17:55

    Just had a rather alarming problem. Left the room for 20 minutes, came back and there was an ear-splitting whine coming through my headphones, if I'd put them on I'd probably be deaf. This was fixed by .. you guessed it, changing the sample rate. Had it at 44.1KHz due to the youtube playback stuttering bug, switched it back to 92KHz and the whining stopped. If this is something that can happen while I'm away from the computer I'll have to start unplugging my headphones at night. Muting didn't stop it, only changing the sample rate did.

    STX II -> HD650 for reference.


    • Aidan35708 Aug 2015 @ 17:58

      Oh yeah, Windows 10 Pro. Sample rate youtube 'fix' doesn't work for me either (think I mentioned this in an earlier comment?) switching between all the sample rates eventually stops it, but it will happen whatever sample rate it is set to beforehand.


    • mzso08 Aug 2015 @ 19:10

      By "whine" you mean white noise. That happened quite a lot to me. Simply stopping and starting playback works fine for me.


      • CarvedInside08 Aug 2015 @ 19:45

        Does it happen on Windows 10 only or did had the problem with previous OSes?


        • mzso08 Aug 2015 @ 20:08

          Didn't happen yet on win 10. But I think all the way from 7 to 8.1, not sure about earlier. But it came up sporadically. Sometimes it was rather scarce, a few times it was quite frequent. Never noticed any particular cause or trends.
          On 10 I have this clicking, crackling problem I previously wrote about.


    • CarvedInside08 Aug 2015 @ 19:58

      Is this the first time you had this issue or did you had it with in your previous OS?

      Issues similar to yours have happen to some people. While these where few incidents the possibility that this could happen and the damage it can done makes me very cautious. I would not recommend connecting headphones directly to the audio card and instead use a headphone amp and keep windows volume at 80-100 and control it from the amp. In the 6-7 years since I got the Xonar card I don’t think I have encountered the high volume noise but I always connect headphones to an amp just to be on the safe side.


      • Aidan35712 Aug 2015 @ 19:13

        This was the first time, and it was NOT a white noise as mzso seems to think, it was an ear-splitting high-pitched tone, and absolutely nothing but unplugging my headphones stopped it. It hasn't happened since, but what has happened since is my audio simply being silent except for the left speaker - right speaker test in the software. This I'm guessing is a windows 10 problem as people are having this issue with onboard sound too.

        One day I probably will get a dac-amp but currently funds are scarce!


        • CarvedInside13 Aug 2015 @ 01:27

          For my information, your headphones are connected to the front panel of the case or to the card?


        • mzso13 Aug 2015 @ 01:54

          Coincidentally I had the first white noise problem show up today on 10. Muting, unmuting soundcard restored normal functionality.

          Is there a way to notify Microsoft of these audio issues? (Something that actually gets read)


  13. Kent08 Aug 2015 @ 21:17

    Hi CarvedInside,

    I have a ASUS XONAR DGX, it doesn't work. I noticed in windows properties it is detected the microphone, but in games and apps such as STEAM (which taps into the system) it ONLY sees a "SoundBlaster Xi-Fi Microphone" but I know this is wrong, because it's not detecting the pink analog port my headset mic is plugged into. Normally STEAM would just say/show "Microphone (Analog port)" etc.

    Here is a DXDIAG paste just in case

    • Kent08 Aug 2015 @ 21:23

      sorry, I meant "ASUS XONAR DGX"


    • CarvedInside09 Aug 2015 @ 12:58

      The whole Soundblaster Xi-Fi is confusing me. Please tell me the exact name of the device that's been under Recording (audio input) device in Steam.

      Which UNi xonar drivers have you tried? Have you tried a reinstall of the drivers? In Windows->Volume->Recording devices is "Microphone Asus Xonar DGX(...)" set as default? Does your microphone work in the voice recording app?


      • Kent10 Aug 2015 @ 00:54

        Hi sorry,

        Ok this is copy pasted.

        Steam says : "Microphone (ASUS Xonar DGX Audio)" and I hit change device, it opens up Windows Sound Control, the microphone is listed as

        "ASUS XONAR DGX AUDIO DEVICE" Pink rear 3.5mm jack

        I have only used the drivers from your page
        "UNi Xonar Drivers 1.75 (post periodically updated)" driver 1816/1822

        I have tried multiple recording apps, skype, steam, and windows Voice Recording app, it's just dead.


      • Kent10 Aug 2015 @ 01:12

        Hi Sorry for the double reply but I just tried the 1.64 R2 as per your note on Win10 compatability (going to the lowest one that is still win10 compatible). As per steam, sound control panel and etc - it's still "Microphone (ASUS Xonar)"

        Thank you though for your time and effort into these drivers, I suppose I'll make do without my mic for the time being or unless you dish out a driver!


        • CarvedInside11 Aug 2015 @ 20:48

          No one else reported that the microphone does not work on Windows 10 with their Xonar card. It could be that your microphone isn't properly connected or its broken.
          Other things you could try:
          Try unchecking and checking the “front panel microphone” option from the Audio Panel or from Windows->Volume->Recording devices-> “Microphone Asus Xonar DGX(…)” Proprieties-> Custom.
          Try your microphone with the onboard audio card and see if it works there.


          • Kent12 Aug 2015 @ 09:05

            Hi Carved,

            I did some testing and fiddling, no avail either.
            I did open the panel and it does look..slightly different? Isn't the main sound panel supposed to show the mic volume and mute? It doesn't but it does show up in the advanced sound control panel, but not in the main. (see screen shot)



  14. Danny Damsky09 Aug 2015 @ 15:24

    How can we be sure that ASUS will even release new drivers for the DGX? It uses the CMI 8786 audio processor which is pretty outdated, it's also not featured on any of the other xonars so I'm not even sure if C-Media will release an update. I wanna know this, because if I'm gonna be stuck using unofficial drivers I might as well upgrade to a FiiO E10K


    • CarvedInside09 Aug 2015 @ 18:18

      We can't know for sure if Asus will release any new drivers. All these C-media chips that are used in Xonar cards be it CMI 8786,8787 or 8788 are using the same drivers. Unless C-Media explicitly removes support of specific chips I will be able to deliver updated drivers for all UNi Xonar supported cards.


      • Danny Damsky09 Aug 2015 @ 18:31

        If that's true, then why is the STX II the only card with a Windows 10 driver on their site? If all chips use the same drivers I'd think that it wouldn't take them this long to release it for the other cards as well


  15. Kenley09 Aug 2015 @ 23:07

    I experienced the Chrome stutter issue until I uninstalled/reinstalled the drivers using the Low DPC option... No more stutter and I changed nothing else. It has to be a driver issue.


    • CarvedInside09 Aug 2015 @ 23:37

      What sample rate settings are you using? I think there are two or more types of shutter issues that have different causes. The Chromium team have implemented a fix for those having shuttering issues at sample rate set higher that 44.1 kHz. That fix is available in the latest Canary build.


      • Kenley09 Aug 2015 @ 23:40

        I doesn't happen on any sample rate I choose and I'm just using a normal build of Chrome. Before I reinstalled the drivers I tried other sample rates with no success, but since choosing the Low DPC option it doesn't happen anymore.
