Pulseaudio crashing in Ubuntu 13.04

view story

http://www.linuxquestions.org – I don't know whether to ask this here or start a new thread. I got Ubuntu 13.04 installed. After that, the first time I tried watching a movie on VLC, I got sound through my Bluetooth headset, but then it cut out entirely. I found a window underneath the VLC screen saying that Pulseaudio had stopped inexplicably. I clicked to have it restart, and restarted VLC too, just in case. There continued to be no sound. I went to Sound Settings, and found that, while the headphones were still recognized and paired, "Connection" was set to "Off." I wasn't able to switch it (HowTos)
