When this happens the headset still shows up as an output device under sound settings, but selecting it as output makes no difference, sound just keeps coming out of my laptop's speakers in every application. I have to run pulseaudio -k (or login/logout) when this happens to get output working again. I haven't been able to reproduce exactly when this happens at all, it seems totally random so far. I'm running precise 12.04 with all updates, but I also experienced this exact issue in 11.10.
