I've noticed similar problem on nexus 4 rc-proposed. I've tried to describe it in this bug report #1524939
This could come from ofono package too (sometime it show x icons speaker, sometimes the bluetooth speaker icon). Even with the bluetooth speaker icon, it's doesn't work sometimes. For me I've to manually disconnect and reconnect or more "forget" the bluetooth car system and do a new connection to it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1528856 Title: bluetooth & car handsfree issue Status in bluez package in Ubuntu: Confirmed Bug description: When playing music through headphone output connected to aux car radio input and going to call someone while driving, i only hear some "beeps" and apparently the call was succesfull but i can't hear anything and no sound is transmitted .
