Thanks — great question. You’re asking what

auto_subscribe

does when you call:

await ctx.connect(auto_subscribe=AutoSubscribe.AUDIO_ONLY)

Short answer: •

auto_subscribe

controls which remote media tracks the client will automatically subscribe to when joining a room. •

AutoSubscribe.AUDIO_ONLY

tells the client to automatically subscribe only to incoming audio tracks and ignore incoming video tracks. What that means in practice: • The client will receive and start delivering remote audio tracks (useful for speech processing, listening, etc.). • Remote video tracks will not be automatically subscribed to; if you later need video you must subscribe to them manually. • Other possible values: ◦

AutoSubscribe.VIDEO_ONLY

— automatically subscribe only to video tracks. ◦

True

(or default) — automatically subscribe to both audio and video. ◦

False

— do not auto-subscribe to any tracks; you must subscribe manually. If you’d like, tell me whether your use case is speech processing, low-bandwidth clients, or something else — I can recommend the best

auto_subscribe

setting and show how to subscribe to tracks manually if needed. Sources: Job lifecycle | LiveKit Documentation | client-sdk-js | livekit/livekit_composite | DeepWiki
