We have wavecyclic miniport WDM audio driver. We would like to remove the
volume slider and mute control for our WDM device in Windows Sound and
Audio control panel.
I read this discussion on freelist:
Where Matthew had responded:
"If you remove the KSNODETYPE_VOLUME node then a software volume APO
will be put
in the capture path; there's always a slider on the Levels tab."
Does this mean that there is no way that we can remove volume slider
and mute control for our device?
I have already tried removing VOLUME and MUTE nodes from the nodes
list that is reported to Filter Descriptor.
Also I have removed volume and mute nodes from connection descriptor
but it does not remove volume and mute controls from levels tab.
