I'm kind of coming up empty...
Can you send a screenshot of the "Configure Speakers" wizard, and one of the
"Default Format" dropdown on the Advanced tab (drop-down opened?)
As I read it, the MSVadSimple driver should support 6-channel and 8-channel
audio. If you install that driver, does the Speaker Configuration wizard work?
CMiniportWaveCyclic::PropertyHandlerProposedFormat
if ((pWfx->wFormatTag == WAVE_FORMAT_EXTENSIBLE) &&
(pWfx->cbSize == CB_EXTENSIBLE))
{
WAVEFORMATEXTENSIBLE* pWfxT =
(WAVEFORMATEXTENSIBLE*)pWfx;
if (((pWfx->nChannels == 2) &&
(pWfxT->dwChannelMask == KSAUDIO_SPEAKER_STEREO)) ||
((pWfx->nChannels == 6) &&
(pWfxT->dwChannelMask == KSAUDIO_SPEAKER_5POINT1_SURROUND)) ||
((pWfx->nChannels == 8) &&
(pWfxT->dwChannelMask == KSAUDIO_SPEAKER_7POINT1_SURROUND)))
{
ntStatus = STATUS_SUCCESS;
}
}

Any ideas ? This is a show stopper for me. I tried a long shot by removing the
device, reboot, and making sure there were no traces left in
.../MMDevices/Audio/Render, then installed the driver again, and at first
activation I exposed it as a 8 ch device (acc to the above), but still the
"Audio channels" list in "Configure Speakers" is unpopulated (!) (whereas the 8
ch USB device I have does have that list populated).
Obviously there is something else I need to do, or do otherwise (i.e.
correctly), but I have no clue as to what atm.
After this I noticed my KSPROPERTY_PIN_PROPOSEDATAFORMAT handler was "commented
out", but when once in again, I cannot get the "Confgure Speakers" dialog to
show at all (!)
I reply STATUS_NO_MATCH here if samplerate is != 44100 or bits != 32 or
channels outside [2,8] range.
Help is immensely appreciated
