View Full Version : [kubuntu] Sound (pulseaudio) stops working

May 22nd, 2011, 07:18 PM
I've been having persistent problems with the sound quitting on me. It simply goes silent. I'm running Kubuntu 11.04 with Pulseaudio. The symptoms I get include these:

1. The pulseaudio volume control pavucontrol says "Connection refused".

2. The Front volume as shown by alsamixer drops to zero (even though I haven't touched it).

3. The pavucontrol output device shows "Dummy Output".

I don't necessarily get all of these at the same time; #2 is the most frequent.

Any explanation has to account for the fact that sound does work most of the time, so probably my configuration is essentially correct.

I haven't been able to determine for sure just what triggers this effect, although it seems to be related to switching audio sources, e.g., from Amarok to web pages.

Should I just report this as a pulseaudio bug?
