Hi Lennart, We found that pulseaudio eats CPU ~19% CPU time, a little more than mplayer when playing video. This is horrible for laptop batteries. Can we make it just work -- in green CPU mode? I can find many users complaining about this, and it seems like some fix is available in this link: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/207135 Thanks, Fengguang
