I'm afraid you didn't understood me.

As you can see from my text and attached images, Specifier field
always is KSDATAFORMAT_SPECIFIER_WAVEFORMATEX. FormatSize (0x40), of
course, is less than sizeof(KSDATAFORMAT_WAVEFORMATEX) (0x52).

In such conditions, my driver fails such requests as invalid.

But these requests are generated by Windows Audio Subsystem on a
regular basis.

My question is: are they meaningful, or there are bugs in Audio
Subsystem code that should be reported?
