I must say that I'm speculating on this particular problem, but I know
that Vista currently has an issue with selection of the input format
used by the audio system. This format normally selected by
right-clicking on the input (the microphone) in the audio control panel,
clicking Properties and then the Options tab. You will see a list box to
select the default format that the audio system will use with that
input. This UI does not currently offer a way to select the number of
channels. We do hope to improve this.
You might be able to work around this by removing mono support from your
driver. The Vista audio system should recognize this and use the stereo
support. Again, I am only speculating right now. Mitch Rundle might be
able to confirm some of this.
A question to you regarding your observation on waveInGetDevCaps: when
you say this reports your device as mono, are you referring to the set
of format flags in WAVEINCAPS.dwFormats? What flags are returned here?
This might be a different issue that we would need to repro' and
investigate here.

Well, the waveInGetDevCaps reports my devise as a mono devise (used to
be
stereo on XP) - an attempt to waveInOpen it as a stereo failes, and when
I
connected my device to a stereo renderer in the graphedit , it was still
opened as a mono device
