Remarks

Returns a list of direct AudioProfile that are supported for the specified AudioAttributes. This can be empty in case of an error or if no direct playback is possible.

Direct playback means that the audio stream is not resampled or downmixed by the framework. 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.

When using this information to inform your application which audio format to play, query again whenever audio output devices change (see AudioDeviceCallback).
