Oh, then there must be a problem with the driver. I have several drivers
that allow a device to opened in stereo mode.
I think there are three places where there could be a problem:
1. Are you sure that your KSDATARANGE_AUDIO is defined properly?
KSDATARANGE_AUDIO PinDataRangesStream[] =
{
{
{
sizeof(KSDATARANGE_AUDIO),
0,
0,
0,
STATICGUIDOF(KSDATAFORMAT_TYPE_AUDIO),
STATICGUIDOF(KSDATAFORMAT_SUBTYPE_PCM),
STATICGUIDOF(KSDATAFORMAT_SPECIFIER_WAVEFORMATEX)
},
2, // Max number of channels.
8, // Minimum number of bits per sample.
16, // Maximum number of bits per channel.
SAMPLERATE_MIN,
SAMPLERATE_MAX
}
};
2. Check the DataIntersection function.
3. Check the SetFormat function.
Check any where in your code where the number of channels is used.
Those are my ideas...but, I can tell you this...For certain I have several
drivers that open stereo input devices that are working in Vista. I think
just knowing it works is 50% of the battle.

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
