pipeline_a2dp_sink_stream works, but it does not support getting song information such as lyrics.

Create input_key_service is an effective way to solve it, please refer

This can only adjust the volume of the local decoding chip, and cannot control the volume of the Bluetooth audio source (such as a mobile phone)
