Enum for audio content type Each value determines a different content type for the playback stream. The content type helps the audio system understand what kind of content is being played, which affects how it should be handled in terms of audio focus and routing.

Possible mappings

Content Type	Value	Description	Focus Behavior	Typical Usage
CONTENT_TYPE_NONE	0	Unspecified content type	Default focus handling	Default fallback when content type is unknown
CONTENT_TYPE_SPEECH	1	Human speech content	High priority for focus	Voice calls, voice assistants
CONTENT_TYPE_MUSIC	2	Music content	Standard media focus, supports timed audio	Music streaming, audio players
CONTENT_TYPE_MOVIE	3	Movie/video content	Standard media focus, supports timed audio	Video players, streaming apps
CONTENT_TYPE_SONIFICATION	4	System sounds and UI feedback	Low priority focus	UI sounds, alerts
CONTENT_TYPE_GAME	5	Game audio content	Standard media focus	Games
CONTENT_TYPE_TONE	6	Simple tones	Low priority focus	Alert tones, notifications

Note: For timed audio playback (synchronized audio), only CONTENT_TYPE_MUSIC and CONTENT_TYPE_MOVIE are supported when used with USAGE_MEDIA.
