Well, the pulseaudio issue is not relevant for the Amarok problems. The Amarok bug manifests itself whenever the sound hardware becomes unavailable, no matter why.
In this case it was triggered by a pulseaudio problem, but that's not relevant. It's Amarok's behavior that blocks the computer. (If you just want to simulate the bug, I _think_ you can install pulseaudio, configure it to intercept alsa, and kill the pulseaudio daemon while Amarok is playing. This should cause the same effect. In my case the bug was caused by Flash 9 hogging the audio server, but really that's another issue. I have a support question up about it.) -- when sound hardware fails, amarok locks the computer trying to play all songs in playlist https://launchpad.net/bugs/85791 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
