On a Nexus 5 running Android 5.0.1, when recording from the bluetooth mic with startBluetoothSco(), the recording switches to the phone mic if the app is switched. Please see below:
The recording is silently switched to the main input mic. SCO_AUDIO_STATE_DISCONNECTED is never received. 03-04 15:13:26.026 1453-2016/?

Wondering if anyone has any ideas about this and preventing it, if possible? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
