Hello, The patch works, I get the a2dp sink consistently through re-connects now. I am still seeing the a2dp-sink profile error in the logs, but other than that everything seems to be fine. bluetoothd[16493]: src/device.c:device_profile_connected() Headset Voice gateway Success (0) bluetoothd[16493]: plugins/policy.c:policy_connect() /org/bluez/hci0/dev_34_DF_2A_0D_F8_C2 profile a2dp-sink bluetoothd[16493]: profiles/audio/a2dp.c:a2dp_sink_connect() path /org/bluez/hci0/dev_34_DF_2A_0D_F8_C2 bluetoothd[16493]: a2dp-sink profile connect failed for 34:DF:2A:0D:F8:C2: Device or resource busy bluetoothd[16493]: plugins/policy.c:service_cb() Added Headset Voice gateway reconnect 0 Thanks!
