I have a fresh install of Windows Multipoint Server 2012. When I first boot, and look at the device manager, the audio output devices are there, proper drivers and everything, just disabled. I can manually enable it and the audio works fine. After I enable the audio device and reboot, it is once again disabled. There doesn't appear to be any conflict, but it just boots up with the audio device disabled.

How can I make the audio device start enabled on boot?

Running a Dell XPS 7800, Quad-core i7, 24 GB RAM.

I found this related question: Enable/disable Windows 7 device via command line and used DevManView to enable the audio via the command line using batch file on startup. I realize that this is not solving the root problem, but it is an effective work-around.

Here's how I did it.

  • Download DevManView (Making sure to download the x64 version and unzip it into c:\Utilities)
  • create enable_audio.cmd with one line: c:\Utilities\devmanview.exe /enable "Realtek High Definition Audio" (your device name may vary, it just needs to be spelled exactly as it appears in the Device Manager)
  • Create a task in the Task Scheduler to run on startup whether logged in or not.

Now on startup, Windows Server will boot and enable the audio device.

You can try this:
Open Registry, go to HK_LOCAL_MACHINE/SOFTWARE/MICROSOFT/WINDOWS MULTIPOINT SERVER then add new DWORD : DisableSystemAudioDevices with value = 0 (if you want to return to default setting of WMS2012 change value to 1).
