### Subscribing to streams manually

When `audio_in_auto_subscribe` or `video_in_auto_subscribe` is disabled, subscribe to a specific participant's stream with `subscribe_to_stream()`, passing [SubscribeSettings](#subscribesettings) to control which tracks are received and at what quality. The `streamId` is available from the `on_participant_joined` event data.
