Public bug reported: Binary package hint: pulseaudio
Description: While playing a media file (video/audio) with any player (totem, rhythmbox, vlc, ...) playback halt for a while, everything becomes slow as though a process has spawn in background, locking all the system resources. Then i hear the sound of the hard-disk spinning as though being busy with some I/O operations. Ultimately the system freezes and the only remedy is a manual reboot. If I hit Ctrl+Alt+BkSpace at the onset of this issue I get some chances of rebooting X to the login screen. How to reproduce: *Login into natty *Enable pulseaudio (if not enabled/installed) *Open a player, e.g. vlc, and reproduce some audio/video *Wait for a while untill playback halt for a few seconds. Then the os becomes unusable. A possible solution: *"autospawn=no" pulseaudio *kill the daemon (pulseaudio -k) Further remarks: The solution outlined above is what led me to conclude that the problem is related to pulseaudio. There are some chances that this is an hardware-related bug, for it seems that this isn't a common bug (also see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/787208). Sometimes, even when using alsa (i.e. with pulseaudio disabled), rhythmbox crashes and vlc playback interrupts abruptly for no reasons. This fact led me to conclude that there must be a problem related to the "audio system" (at x server level maybe, I'm not sure...) that causes some crashes, and the reaction of the pulseaudio daemon is "bad", in the sense discussed above.
