Yes, I have seen this post, thanks.
Ok, I can use DeviceIoControl but I do not understand how to call
DeviceIoControl to device returned by DShow enumerator
(CLSID_AudioInputDeviceCategory).
I do not see any common handle that I can use later to call DeviceIoControl.
Any ideas?
I'm doing filtering by friendly name now and it looks like I will keep using
such approach. It's sad..
Thanks.
