During link loss, previous AVDTP session is not freed due to wrong session "ref" count. When ever the START_CMD received from the remote headset, avdtp session ref count will be increased. Because of this, new A2DP connection will fail. This issue is handled with AVDTP session free in case of linkloss (EIO 5) irrespective of ref count. //If bluez receives START_CMD twice and ref count increased accordingly Sep 19 13:54:46 localhost daemon.debug bluetoothd[661]: profiles/audio/avdtp.c:avdtp_parse_cmd() Received START_CMD Sep 19 13:54:52 localhost daemon.debug bluetoothd[661]: profiles/audio/avdtp.c:avdtp_parse_cmd() Received START_CMD //During session disconnection due to link loss, session is not freed.
