Comment 10 for bug 2009271

Same here - I cannot be certain, but for me it seems to be triggered after screensaver is unlocked. I will return to the desktop, unlock the screensaver, and notice that pulseaudio is taking 100% and audio is no longer working. Sometimes pulseaudio -k will restart/fix it. But other times it will not. See tons of

in the syslog. /var/log/syslog also filled my hard drive due to this message.

This problem started happening in the past month or so for me.
