The mix format is the format that the audio engine uses internally for digital processing of shared-mode streams. This format is not necessarily a format that the audio endpoint device supports.
The GetMixFormat method retrieves the stream format that the audio engine uses for its internal processing of shared-mode streams. The method always uses a
WAVEFORMATEXTENSIBLE structure, instead of a stand-aloneWAVEFORMATEX structure, to specify the format. -
