[Bug 668732] [NEW] choppy audio

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Ubuntu 10.10
Audio playback is choppy (like if cpu can't "run" fast enough).
Pulseaudio: 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu21.1.
I expect smooth audio AND video playback as before (previous distro was Mandriva 2009.1), expecially if the computer is doing nothing else; instead, audio is choppy (and video too).
Already tried suggestions in forum (like load-module module-udev-detect tsched=0 in /etc/pulse/default.pa).
Also, when it happens, it seems moving mouse is choppy too (like if the system were very loaded for a while).
