Hi All

I'm trying to get audio working in server core(Standard R2 SP1)

i've tried the following ....

Added 'AudioEndpointBuilder', 'AudioSrv','HDAudBus', 'Class', 'DeviceClasses' and their relevant data to the system registry, also added the relevant data in 'services' but with no joy

Driver loads, but with "Invalid Data"

Any ideas??, have i missed something?

Any help much appreciated

Any ideas??, have i missed something?

Surely, Server Core does not support audio. See the following:

General Development Considerations for Server Core

Absolutelly correct........however it can be modified to run audio, i'm just not sure how, same as it's not desinged to have a gui...................

Getting closer.... audio service is running now including dependencies....i was missing some entry's in the registry. just the driver loading to sort out.....nearly there!!.....

Well, this is the closest i can get, everything works apart from the loading of the audio drivers, just cant seem to get it to load them.............

Might want to run process monitor on that machine while installing the driver to see what file can't be found.

Thanks for your suggestion , I found the problem, .... Ksthunk.sys , the os seems to think its an unsinged driver, i ran "bcdedit -set loadoptions \DISABLE_INTEGRITY_CHECK" now running the os in "Test" mode and made a developer certificate for Ksthunk.sys, now the driver loads and installs, everything appears ok, but still no audio.....................i'll keep trying .......................
