1. The audio driver need to get the session status callback as the sessionEnded 2. Update the invalid audio configuration based on the session type Bug: 197296692 Bug: 150670922 Test: HAL 2.1/2.2 work for A2DP software/hardware media, and LE audio software media/voip call Test: Turn on/off bluetooth to make sure the onSessionEnded work well Change-Id: Id758b556e8f5c9b63052a408154f02082515091c
