[audio/sysvad] APO_BUFFER_FLAGS not used as flags in sample

[kurylo]

Is the APO_BUFFER_FLAGS handling implemented in the SwapAPO using switch statement correct?

Windows-driver-samples/audio/sysvad/APO/SwapAPO/swapapomfx.cpp

Line 245 in b968cfb

case BUFFER_VALID:

Name flags suggests that multiple flags can be set at once e.g.: both BUFFER_VALID and BUFFER_SILENT with a resulting value of 0x3. This would require a different handling than a switch statement.

Clarification in the document:
https://learn.microsoft.com/en-us/windows/win32/api/audioapotypes/ne-audioapotypes-apo_buffer_flags
is needed on whether the ppInputConnections[0]->u32BufferFlags are to be treated as flags (as the field name suggests) or as an enumeration with only one value valid at a time. The current wording in the document using both enumeration and flags is ambiguous.
