Remarks
Returns a bitfield representing the different forms of direct playback currently available for a given audio format.
Direct playback means that the audio stream is not altered by the framework. The audio stream will not be resampled, volume scaled, downmixed or mixed with other content by the framework. But it may be wrapped in a higher level protocol such as IEC61937 for passthrough.
Checking for direct support can help the app select the representation of audio content that most closely matches the capabilities of the device and peripherals (e.g. A/V receiver) connected to it. Note that the provided stream can still be re-encoded or mixed with other streams, if needed.
