Something in Karmic is causing the volume of sound to mute whenever a system sound is played. This started I believe yesterday evening August 15. This has been a problem in the past where certain sounds would automatically drop the volume down or raise it out of control, but this is the first time I have seen a total drop-out of the master volume all the way to 0. Things like this seem to happen when pulseaudio is updated. If you are uninstalling pulseaudio, simply resetting your master volume should get you talking again. For me, it's more than a small annoyance, because I try to use pulseaudio, even though I really don't need it because I have a SoundBlaster Live which does hardware mixing.
