The 1.75 drivers come in two variants:

1.75a

Driver for previously supported cards. Same audio drivers as those in 1.72 (1816 for Win XP , 1822 for Windows Vista/7/8/8.1/10).

    Hi,
    I installed the ASUS Xonar drivers and they really suck. I tried to download UNI Xonar drivers from the links give but my virus scanner stopped the download and removed it saying it contained malicious software. this was both the v1.75a and v1.72.
    Where can I download a safer drivers?

    Hi,
    Thanks. I removed download from quarantine in the virus scanner and installed Much better. However, still not getting output from speakers e.g no sound from front left but from front right. Its late in the evening but will try and seek if swapping cable connections make any difference. Watch this space.

      Hi,

      I tried cable swapping got very confusing. So I uninstalled the drivers and cleared out drivers as suggested in FAQ then reinstalled the drivers. The sound output from various speakers is as it should be and others is toppy turvy. E.G. using the speaker selection on the Xonar panel –
      when you click the L speaker the sound comes out of Front left as expected.
      When you click centre the sound comes out of side left speaker.
      When you click the right speaker the sound comes out of the front right as expected.
      When you click the sub the sound comes out of the side right speaker
      When you click the side right the sound comes out of the front right and centre speakers
      and when you click the side left the sound comes out of the centre speaker.
      How do I resolve this?
      I have disabled the on board sound system in bios. I was wondering if switching this back on will any difference. Will this also restore the front jack for headset as I get no sound out of this as well.

          Yeah it’s weird, i’d guess you have a DX? The information they give in the manual and what’s on metal plate is completely different from what the actual sound channels are. I don’t know how ASUS managed to screw that up.

            Hi, It seems they have carried the omission into the DGX card as well.

          I have also noticed that when I test the sound quality from each speaker using the ASUS interface the sub woofer output is very low and not very clear compared to the same test done with the windows playback menu. Have I missed something in the installation?

          I have noticed that everytime I try to configure the recording using he windows recod menu the computer crashes and gathers info to send and the computer restarts. Is this due to the sound card or the drivers?

    hi, congratulations for the continuous modding drivers asus. I hear the sonic differences between the original drivers Asus Xonar is the last UNi v1.75b rev.2 with my ST. I made measurements with RMAA and I noticed, however, that the original drivers give better measures such as THD and SNR. What do you think?
    Thanks.

    Reply

    • CarvedInside    08 Nov 2014 @ 18:06   

      Thanks. I haven’t done any RMAA tests for 1.75b drivers. Will do some tests later and see if I get the same behavior.
      Did you have the same sample rate in Xonar Audio center when you did the tests? What was it?

      You can try the 1.75a drivers as they will be the same as original drivers in this regard.

      Reply

      • CarvedInside    08 Nov 2014 @ 23:46   

        I’ve ran the RMAA tests and the overall results are the same between the drivers. With both drivers (1.75a vs 1.75b) I used C-Media Panel, 16bit as depth output, 44.1 KHz as sample rate on Win7 and Xonar DX card. Ran the tests twice for each driver. I like to add that there is no reason 1.75a drivers would behave differently or worse than using original drivers, especially if compared to same version audio driver (1822). From time to time I’ve done RMAA tests between newer and older audio drivers and never seen a difference, at least not in favor of older drivers.

        Either you had different settings on the original drivers(different sample rate maybe?) or you used an older driver version that somehow performs better. What’s the version of the original drivers you’ve tested? What’s your OS?

    Anyone else have a problem on Windows 8.1 x64 that sometimes installing C-Media Panel fails to install properly? I reinstalled my PC completely and i installed Uni Xonar for my DX, but C-Media Panel didn’t install properly(When trying to search for C-media only some weird file shows up in the results which says that there’s no Hardware supporting C-media)

            It only happens sometimes, i don’t know i never do anything different when installing. However i have noticed something strange when installing:

            Whenever the installer finishes it asks me to restart, i press restart but then the installer is keeping me from restarting so i have to force restart, or cancel and click “Finish” in the installer. Is this a bug? Maybe its also the reason why this happens. Last time i installed i click to restart later, pressed finish and then restart.

            • CarvedInside    12 Nov 2014 @ 21:33   

              I don’t think this is why C-Media does not work sometimes.
              You are prompted to restart by the audio driver installer (made by C-media) which is launched by UNi Xonar installer. In most cases you don’t need to restart after audio driver installation. If you wish to restart after driver installation, do it manually after the UNi Xonar installer finishes.

    Something is strange with WINDOWS 10 x64, Xonar DX and all your current drivers 1816/1882 & STX II 11.5 1.75

    When playing different games, and having youtube usually open in Chrome these errors occur. (or to say when using sound it happens, if no audio is playing it doesn’t happen. And it seems to require a game playing, as I don’t remember it happening from just youtube. But it is all games, BF4. Trove, EVE Online, TF2, Titanfall. Though it is possible it would, as usually I have a game open pretty often if I am near my computer (not giving much time for it to occur otherwise).

    The Audio Service will crash. I will have to right click and Speakers on the Taskbar and click on Playback Devices, and it will restart the Audio Service, making me having to reopen any applications that use sound as they won’t be registered. This happens a lot.

    To make matters worse, seemingly 60% of the time this happens, restarting the Audio Service will do nothing at all. Sound won’t come out at all. I have to uninstall and re-install the audio driver, as rebooting the operating system will not fix the sound issue at all. Again, usually when I have no sound at all, restarting the computer will no fix it, I have to clean uninstall the driver and re-install.

    This happens on average 1 to 5 times a day. I can’t for the life of me figure out what could be causing it.

    I am having issues with both the Asus Xonar DG drivers and the Unified Xonar Drivers on Windows 8.1 64-bit.

    They both install fine, but the buttons on the interface will flicker/blink a lot and then the application crashes after sometime (few minutes to an hour later).

    The drivers worked fine when I had Windows 7 last week and i’m not sure why it’s happening with Win 8.1 and how I could go about fixing it.

    I was unable to set a Bit-Depth other than 16-bit in ASIO Control Panel after update to 1.75a rev.2. Then i’ve opened ASIO Control Panel from foobar, not from XonarSwitch and set 32-bit, now it’s ok. Just if someone will face it too.

    So I am getting my ASUS Xonar DG Sound card Wednesday,And this driver will work for it?
    And I use a pair of Turtle Beach Z22’s headphones connected to the DSS2 Dolby Digital Surround Processor,So I will be using the S/PDIF out(Optical Toslink) for the audio out.
    Now my other question is: Do I set the onboard audio in the BIOS to (Auto,Enable, or Disable)?Because I need the USB for the Mic.

    Hi, I have been using your drivers for a long time and thank you for your hard work. A friend told me that when I speak on Teamspeak 3 it sounds like am lagging however am getting no packet loss and he recommended that I use DPC Latency to see if I had any problems. I did notice if am using no sound related programs am sitting at 60-80µs if I launch for example TS3 and join a server it jumps to 230µs-334µs. The same happens if I launch VLC. Am using Windows 7 64-bit Service Pack 1 with UNi Xonar 1816/1822 v1.75a r2 with Xonar DGX. I have re installed everything and the same results happen again.

    • CarvedInside    19 Nov 2014 @ 21:09   

      DPC latency is a different thing than Input(Line-in or microphone) latency. I don’t think DPC latency would have a impact on speaking lag. There could be multiple things that could be responsible for a delay in Teamspeak conversation. Internet latency from your end or your friends end could be responsible for example.
      You had this problem using original drivers or UNi Xonar with Normal configuration?

      You could try and see if you get the same lag with microphone connected to the onboard audio card instead.

    Uni Xonar drivers (175a r2, I think) are still crashing in Windows 10 occasionally. It happens very seldom, but currently they are the only thing cited in even the very occasional BSOD.

    Any chance the Unified Xonar Drivers will in some future release support the C-Media CM8828 chip-set?
