Is it possible to get DirectSound to select an input line in Vista? I know I
can enumerate devices and lines (actually just devices in Vista) but when I
try to capture from a line, using the CaptureSound sample, the line just
keeps being muted in Vista and silence is recorded. However if I manually go
into Sound->Recording Devices and look at the properties for the device, I
can see that the device is, by default, muted.
Is there any way to let DirectSound control the mute state for the
lines/devices? The best thing would be muting everything I do not wan to
record and un-mute the device I would like to record from.
My aim is simply to build a line selection tool with a volume meter -
similar to the one in Live Messengers Audio Settings. Are there any concrete
examples on that?
