The type of audio stream is determined by StreamUsage for playback streams and by SourceType for recording streams.
The audio stream type significantly affects volume control, audio focus management, and the selection of input/output devices.
Applications should select the appropriate audio stream type based on their specific service scenarios and requirements.
WebView policy: Currently, manually setting the audio stream type is not supported. WebView automatically assigns the stream type based on whether there is audio input. If there is a playback stream but no recording stream, it defaults to the Music type. If there are both playback and recording streams, it defaults to the VoiceCommunication type.
