Comment 12 for bug 1494225

Looked through Pat's log file and it actually shows that the HFP profile is never correctly connected due to

Mar 1 13:26:27 ubuntu-phablet bluetoothd[739]: src/profile.c:ext_connect() hfp_ag connected to 00:18:16:20:00:FE
Mar 1 13:26:27 ubuntu-phablet bluetoothd[739]: src/service.c:change_state() 0xb775f8b8: device 00:18:16:20:00:FE profile hfp_ag state changed: connecting -> disconnected (-5)
Mar 1 13:26:27 ubuntu-phablet bluetoothd[739]: src/device.c:device_profile_connected() hfp_ag Input/output error (5)

That is the reason why audio is never routed throught he headset. Needs more investigation to find out what the reason for this is.
