first sorry for my simple English.
Now I try explain my problem: My bluetooth headset Philips SHB7150 not working (propably accu) and Philips service exchange it for new one. Now when I connect the new headset with other computer with windows or android, everything is fine. First pairing and connecting was good, icon my headset show up in sound menu and I can select this as sound source. I hear sound in both mode: A2DP and HSP(mono). But when I reconnect headset I don't hear any sound in any mode. Additionally when I change HSP sound mode on A2DP system automatically unselect my headset as sound source. Until after many trails only when I set sound mode in HSP before disconnecting headset and reconnect I hear sound in both sound mode.
I have different headset (Motorola S305) and this one work perfectly. I can reconnect without any problems.
Any idea why?
Can I somehow delete any info about Phillips headset in ubuntu and do fresh start?
I hope I explained my problem well.
