View Full Version : [ubuntu] PulseAudio dies and sinks/sources won't reconnect

Recently, my PulseAudio daemon has taken to periodically dying. I haven't nailed down exactly what's happening, but it started happening after I began using a pair of USB headphones and seems to have something to do with plugging/unplugging the headphones and suspend resume. It would be great if I could fix this problem (though I'm not especially hopeful), but that's not why I'm posting. (I've posted the output of grep pulseaudio /var/log/messages below, in case it holds any clues.)

I've figured out how to restart the daemon, by running "pulseaudio -D". But it seems that sources and sinks have a problem connecting with the new instance of the daemon: I have to restart Firefox and Amarok to get any sound out of them; right now, I can't get any sound out of my built-in speakers or speaker output.

Restarting apps and rebooting the system when PulseAudio craps out is a big pain. Is there any way to get sinks and sources to attach themselves to the new daemon without going through all that?

Maybe yes. I've got logitech usb speakers. In Xubuntu, go to Applications, then Accessories, then Terminal. In Terminal, type

asoundconf set-default-card 1

Then close and re-open your browser (Mozilla Firefox) or restart your system.
:KS
Note, if you unplug your usb speakers, your laptop speakers will take over. In order to re-establish contact with the usb speakers, you will need to (plug them back in) restart the system.
