Comment 12 for bug 207135

Also have this problem. I just upgraded to intrepid and it has not improved. For the record, about 9% usage on halfspeed on a turion tl52 1.6GHz

As a bonus when choosing alsa instead of pulseaudio in audio settings flash breaks, possibly more. Used to work great, in kubuntu at least.

<rant>I don't really know what pulseaudio is supposed to fix, it's nothing but trouble, please make it go away</rant>
