Detailed Description


  1. AVRCP 1.0 shall be supported initially. AVRCP passthrough commands shall be handled internally via uinput
  2. A2DP data path shall be handled via a socket pipe between the AudioFlinger android_audio_hw library and the Bluetooth stack.Represents the standard BT-AV interface. Used for both the A2DP source and sink interfaces.
