Unfortunately, Fibonacci's account (swapping "Intrepid" and "Jaunty", of course) seems to be true for me too. Flash has gone silent for me after about seven days. No other apps were affected, so pulseaudio does seem to have restarted itself. The usual Firefox restart works around the problem, as it did before.
The pulseaudio message in /var/log/messages is: pulseaudio[3441]: protocol-native.c: Failed to push data into queue last message repeated 44441 times -- Can't play sound because of pulseaudio hang https://bugs.launchpad.net/bugs/288093 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
