Rebuilding OutputStream and Sinks after stream invalidation on Android #836
Description
On Android I noticed that the OutputStream becomes invalid when the audio device changes, for example when Bluetooth headphones are connected. This can be detected via with_error_callback.
When this happens I have to recreate the OutputStream. As a consequence all Sinks tied to that stream must also be recreated.
The problem is that Sinks hold important state like queued Sources, playback order, volume, paused state, and the current playback position inside a track. Recreating Sinks causes all of this state to be lost.
Is there an official or recommended way in rodio to handle this situation?
Should applications keep track of all Sources and Sink state manually and reapply everything to newly created Sinks?
The goal is to continue playback seamlessly after the OutputStream is rebuilt, without breaking behavior or restarting audio.
Is there a recommended way to handle this use case?
