Detailed Description

Bluetooth A2DP audio sink: stream PCM to a connected speaker.

Adapts the push-style Audio sink interface interface to the A2DP source, which pulls PCM from the Bluetooth stack's own task. write() feeds an internal ring buffer; a pull callback drains it and the stack encodes SBC and paces the link. Requires the Bluetooth service service to have an established connection.
