Title:
Lucid: pulseaudio causes many wakeups while playing music
Status in alsa-driver package in Ubuntu:
Fix Released
Bug description:
Binary package hint: pulseaudio
While playing music in rhythmbox or totem pulseaudio causes many CPU-
wakeups as can be seen with powertop. When rhythmbox is on but not
playing any music the CPU-wakeups are much lower.
I will attach the output from 'powertop -d' while
- rhythmbox playing music (playing)
- rhythmbox not playing music but loaded (idle)
As I can't remember ever seen such behavior in previous versions of
Ubuntu I think this is a bug.
