But if I decrease supported number of channels, reinstall the driver and then
increase number of supported channels again (KSEVENT_PINCAPS_FORMATCHANGE is
generated by the driver), test tone playback still failed for new number of
channels.
Can you file a Windows Feedback "problem" report for this and send me the link?
Start | Windows Feedback | Hardware, Devices, and Drivers | Audio, sound, and
volume | Add new feedback (you may need to do a trivial "search" to get it to
light up) | change feedback type to "problem"
In Win7/8, there are no such issues. Only in Win10.
Yeah, the format support cache is new for Windows 10. > BTW, why Endpoint
Builder doesn't use
KSPROPERTY_PIN_CONSTRAINEDDATARANGES property request, querying for each
possible format instead?
I don't know.
