can pair and be headset service but no sound nor appearance in pavucontrol

[gregrwm]

first time i tried my csr 4.0 dongle and bose series 2 the headset appeared in pavucontrol, and i used it successfully with linphone for 34min, suddenly i couldn't hear anymore, other party said there was some silence then could hear me again, i could see her voice on linphone's meter but hear nothing, then i got some dialog requesting i (re?)authorize some bluetooth something, too bad i didn't copy that down at the time. apt-get upgraded, rebooted, tried another partition that wasn't upgraded (both saucy), tried precise, but it has never worked again. both the bose and another headset (bt-15k4) can pair and be selected for headset service, but do not show up in pavucontrol, nor work. both work on my phone.
