Notes about Windows 10 RTM compatibility (updated 27 Aug 2015)

UNi Xonar drivers above v1.64 will work in Windows 10 but since the audio drivers are not yet made specifically for Windows 10 there could be some issues that you could run into depending on audio settings used. Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions.

Apart from driver issues there could be issues solely from Windows 10 sound system that would be fixed with future Windows updates. There is also a small chance that some things could break with future Windows updates.

100% compatible drivers when?

Because of the very slow development of the audio drivers by C-Media and the long time it takes for C-Media partners (ASUS and HTOmega) to release the new drivers it may take a while before we have a 100% compatible driver for Windows 10.  If we are lucky we will have new audio drivers in 2-3 months after Windows 10 RTM launch. As soon as new audio drivers became available I will release a new UNi Xonar drivers package.

About Chrome shutter issues on sites like YouTube. (27 Aug 2015)

Update 27 Aug 2015: The shutter issues on youtube are  fixed with the latest Chrome build released on 20 Aug 2015 (v 44.0.2403.157). Reports indicate that shutter issues are still happening for videos on other websites (eg. daily motion, facebook, instagram).

Update 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 or Chrome.

There is a Chromium issue opened here.

Here are some things you could try:

  • Change Chrome audio buffer size.
  • Change/keep sample rate to 44.1 kHz both in the audio panel and Windows Volume->Playback devices->(…) Audio Device Proprieties -> Advanced -> Default Format.
  • Change sample rates back and forward a couple of times.

    Hi, since I’ve installed Win 10, the Fixsoundloop.bat doesn’t work anymore. It usually restarted my XonarD1 and fixed problems like the name says, or if the right or left speaker was louder/quieter than the other. Now it only displays the message:

    SERVICE_NAME: audiosrv

    Has the PCI number changed so this line from the .bat isn’t applicable anymore? “@devcon enable PCI\VEN_13F6”
    Any help would be appreciated.

    I was seeking through a YouTube video when suddenly continuous max-volume screeching glitchnoise was pounding through my speakers, way past the system volume level I was at. I’m wondering if there’s any precedent of these drivers fixing this specific issue. I think I’m going to ditch the card, I can’t risk damaging my equipment or my hearing testing such an atrocious bug. These cards are dangerous.

    System:
    Xonar Essence STX
    44.1k / Hi-Fi Mode enabled
    Default ASUS Windows 8 64 bit drivers
    Windows 10 Pro 64 bit
    Firefox 40.0.2
    HTML 5 YouTube player

    I want to report this problem “Possible issues:
    Occasional Left or Right speaker imbalance or volume drop. This is a different issue that the L or R volume drop issue that some people have regardless of the drivers they install. There are 2 user reports for this issue.” too. My drivers are 1.75a and I run Windows 10, my sound card is Asus Xonar DX. I tried everything in mind but it didn’t work to re-balance the volume difference (like restarting the audio service, trobleshooting the audio hw/sw etc). I need to restart the PC to solve. It happened 2 times for now and always on my left speaker ( the main one ).

    Just FYI, here is a post from an ASUS employee with a timeframe for new sound card drivers: http://www.hardwareluxx.de/community/f248/windows-10-support-mb-soundkarten-wlan-1082206-4.html#post23776651

      Thanks for sharing. At the moment ASUS seems to not release any new drivers, just changing the supported Windows version in the installer from their old Win8.1 drivers. So there might not be any new audio drivers in September or October either.

      Ouch. October for my D1… And the crackling problem doesn’t seem to go away. (There were numerous windows updates)

      No planned update for the D2X, but planned update for the DX? What are they smoking?

    My 6 August post seems to have been lost amongst the noise, so I thought I’d re-post it in the hope someone can help me…

    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

    I’ve just purchased a STX (not the STX II which is far too expensive where I live). It is replacing my trusty but aging D2X which has done sterling service for four years.

    I’m running Windows 10 Pro. Before installing the STX I in addition to uninstalling the old drivers I also did a thorough registry and file clean up using CCleaner and Driver Fusion. Once the card was in the PC I installed the 1.75a-r2 drivers (low latency option). They installed with no issues after a reboot. I’m happy to report everything works fine (also using Xonar Switch. So a big thanks to those who contributed to the development of the drivers and Xonar Switch.

    Hi. I have a strange issue. It’s not a deal breaker, but if possible, I’d like to know how to fix it.

    After I install the latest Uni Xonar drivers for D2X card on Win 7 x64 and I restart, I get the blue CMedia Panel icon in the notification area. But on the next restart, the icon disappears. From the start menu, I found out its location is C:\Windows\System32\CmiCnfgP.cpl and I can make a desktop shortcut that way and use it.

    Now, to be completely honest, this started happening after a round of windows updates followed by disabling some windows services.

    In any case, can you tell me if a Windows service is required for the notification area icon to appear every time? Or is it something else, like a scheduled task?

      Hi. Which panel configuration have you selected when you installed the Uni Xonar drivers drivers?
      There is no service related to autostarting C-Media Panel, it is a startup entry which can be controlled from Run->msconfig->Startup tab->”CmiCnfg Dynamic Link Library” entry.

      You can either reinstall the drivers with C-Media Panel panel configuration, re-enable from msconfig or add a C-media Panel shortcut to Start->Programs->Startup.

    Hello,

    Is it possible to change the settings available in Xonar Control Panel without having it installed? I have only the drivers installed and am wondering if it would be possible to do so and if how?

    Reply

    • CarvedInside    27 Aug 2015 @ 23:38   

      Hi. For some settings you could use the Standalone applications that are available in the download section of the post above. You could change settings in the registry but you have to know which key does what and I don’t have a manual for that. For the registry settings location see FAQ Q&A5.1.

      I’m curios, why do you not use one of the Xonar cards control panels (Asus Audio Center, C-media Panel or Xonar switch) to change the cards settings?

    I am on Windows 10 64 bit using Asus Xonar DG (just purchased a few days ago), installed the latest driver update from this site. Everything was working fine for a few days, while I was playing LoL, the sound suddenly got distorted where I can only hear a faint background music, with no foreground vocals. This problem is happening within Chrome, VLC, LoL, basically from any audio source.I tried to install the official driver from Asus to see if it would work, but it says it’s incompatible with my OS. I will try to install the previous unified driver and see if it will work. But I am thinking that it may be a hardware issue now. Anyone experiencing similar issues?

      Disable GX if you didn’t already. If that does not fix things, you could try installing the drivers with Low DPC Latency option.
