Thanks Mathhew ! Its installed now :)
There were further references to this vaddyn.sys in the inf file which I
removed.
Can you please tell me how I can enable some traces of portcl.sys,
audioeng.dll and audiokse.dll. And does the sample include some test which
I can execute to see the audio playback/record functionality?
