Comment 4 for bug 1537737

Here some logs in attachment (I think in the first 10 minutes)

Explanation :

How it works :
1. Turn on the headset --> bluetooth connects automatically the headset (already paired in the past)
2. Make a call --> dialer-app show the bluetooth icon by default
3. No sound for the call (even in internal phone speaker), if you switch back to phone speaker option the sound is back in internal phone speaker
4. Switch back to bluetooth --> still no sound
5. Disconnect manually from headset and reconnect (in settings>Bluetooth>device name)
6. Make a call --> The sound is now routed to headset

How it should work :
1. Turn on the headset --> bluetooth connects automatically the headset (already paired in the past)
2. Make a call --> dialer-app shows the bluetooth icon by default
3. The sound is routed to the bluetooth headset
