Install Xonar DSX on Windows 2012 Server

by peterdk on March 14th, 2013

I have a little home server running in my livingroom, and I recently installed Windows 2012 Server on it. Because it’s always on I figured I could use it as a Airtunes receiver too. I installed shairport4w as a service and now it runs great!

However, I wanted to try a better soundcard for it, so the audio quality would be even better. Therefor I bought a Xonar DSX.

Unfortunately this soundcard wouldn’t install when I ran the windows 8 drivers. It gives a message that the OS is not supported. Strange, since it’s the same as Windows 8. Probably a case of a little too strict checking.

Anyway, solution to install Xonar windows 8 drivers on windows 2012:

  1. Download Windows 8 driver for your Xonar card.
  2. Extract the zip file.
  3. Open the win8 dir (do not run setup in the dir above it)
  4. Edit the file CmSetx.dll with notepad. (it’s not a binary file, just a txt file)
  5. Change the line with ¬†SupportOS to “SupportOS=donotcare”
  6. Save and run the setup in the same folder.
  7. It will now install and work ok!

This will probably also work with DGX, DG, DS, and other Asus Xonar cards.

    Server 2012 R2 w/ Xonar DX

    I can get it to install, but no sound with windows 8 or 8.1 drivers. My display driver (AMD) crashes sometimes when I’m trying to test audio.

    Tried Installing the Windows 8 and Windows 10 ASUS Xonar DG and edited the above mentioned CMSetx.dll. Sometimes it installs sometimes it doesnt but never works on my Windows 2012 R2 machine. Any other troubleshooting options?
