I installed linux-backports-modules-alsa-lucid-generic and powertop
reports 32,7 wakeups now when playing some music with rhythmbox. So it
is better. Don't know if it was better in previous versions.

[Daniel T Chen]

Can you reproduce this symptom with today's (or newer) snapshot of
linux-alsa-driver-modules?

Does not help. Tried it with kernel 2.6.32-22-generic + linux-alsa-
driver-modules from the mentioned ppa.

Re: [Bug 574037] Re: Lucid: pulseaudio causes many wakeups while playing music

[Daniel T Chen]

This symptom should be largely fixed in the latest alsa drivers;
please try linux-alsa-driver-modules-$(uname -r) from
ppa:ubuntu-audio-dev. (Make sure you're using the release kernel and
not -proposed's.)
