The 1.75 drivers come in two variants:

Read Previous Release Notes

 

Note about Windows 10 Tehnical Preview builds compatibility (updated 28 Mar 2015)

UNi Xonar drivers above v1.64 will work in Windows 10 TP but since the drivers are not made for Windows 10 TP there could be some issues here and there (e.g.,  this one). Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions.

Due to changes within the Win10 TP builds and the very slow development of the audio drivers by C-Media, it may take a while before we have a 100% compatible driver for Windows 10. It could take up to 2-3 months after the final release of Windows 10.

    I’ve been running this driver for a long time, with no issues. Just recently, I had to restore my computer. I then reinstalled the driver, which was an older version, and sound works fine. I can’t for the life of me, get the microphone to work though. I’ve made sure that the front panel microphone box is unchecked, made sure the window settings are correct as well. What can I do?

      Try reinstalling the driver. Try different drivers. Check if the microphone works with onboard audio card.

        I believe I may have found the problem. My headset wire, has a knick, and it looks as though the microphone wire has been cut. I’ve ordered a new headset, which I believe will fix the issue.

      Which audio panel are you using for enabling Dolby Pro Logic II? Have you tried with previous driver releases like v1.64 or v1.70?

    Hi!, i currently have a 5.1 headset Real (4 speakers per side) in the original menu Asus, can amplify the stereo headphones, but it is impossible to have to select 5.1 output, is there any way to amplify the headphones in 5.1 as in the case of stereo headphones?

    Reply

    • CarvedInside    28 Mar 2015 @ 18:38   

      Are you referring to headphones impedance options? That’s not possible to use that in a 5.1 setup.
      If you need a higher volume you could raise each channel volume slider from the Mixer tab.

    Hello – I’m really liking this driver, unfortunately it doesn’t fix my big issue with the standard driver. Basically, I have to toggle onboard audio on/off through BIOS in order to use my Asus Xonar Essence ST card. If my onboard audio is enabled it will seem like the xonar works when you look at the output (well, animations) of the sound, but no sound comes through my headphones. In short, I have to turn onboard audio off in the BIOS to use my headphones. I would love to be able to switch back and forth between them (and yes, this is easily possible, except there is no sound coming from the headphones, even though sound animations are going up down up down). I don’t know if there’s a fix for this… I’ve looked. So I was hoping you’d have the answer to it <3

      Hi. Which OS do you have? If you disable the onboard audio card in Device Manager, does the sound come out of the Xonar card or not?
      By output animations I assume you are referring to the device output’s visualization in Windows Volume->Playback Devices. But does that correspond to the Speakers ASUS Xonar ST Audio Device?
      Check that you have set “Speakers ASUS Xonar ST Audio Device” as default in Playback Devices when you have the onboard card enabled and check in the audio/video player settings that the output device is either Windows Default or the Xonar ST card. If those settings are correct you should look into updating your motherboard BIOS if newer versions are available.

        Hi, thanks for the reply.

        I’m running Windows 7 on an ASUS p8z68 board, latest BIOS driver (although, it was released 2012).

        I tried disabling it in the Device Manager, but it made no difference unfortunately. I’ve also tried removing Realtek Audio Driver just in case, but no dice.

        Yes indeed it does correspond to the correct audio device, it’s even showing the animations in the Xonar Audio Center application.

        When I boot to linux it works just fine to switch between the devices, of course there’s no special driver installed then, just some standard one.

          Update your Windows if you’ve haven’t applied updates. Try plugging the ST card in different PCI slots. Try different UNi Xonar driver versions. If none of these help, I think it’s an issue with your motherboard (which could have been fixed through Bios updates if ASUS cared). Here is a similarly strange issue that’s was caused by the ASUS motherboard.
