Hello,
I have constructed an audio driver that currently consists of a WaveCyclic
filter and a Topology filter. The topology I expose from these filters appears
fine in Windows XP and KsStudio. However I am not having as much luck within
Vista…
When the ‘sounds’ applet from the control panel in Vista is opened the correct
playback and recording endpoints appear and have the correct properties
associated with them (i.e. volume, mute, etc). However a red cross appears on
the speaker in the system tray and the message “No audio device is installed”
appears when I click on ‘Open Volume Mixer’…
I’ve searched the archives for this group and browsed the internet but cannot
find any clues as to what may be causing this. Does the group have any
suggestions? Or can someone point me in the right direction, particularly in
where I can find documentation regarding the way in which Vista (or XP for that
matter) discovers the driver’s topology.
Most of my topology’s pins have custom names; does Vista look for specific
names?
Thanks,
Andrew Murray
