Comment 65 for bug 381201

I found that setting the Module-options

power_save=0
and
power_save_controller=N

in
/etc/modprobe.d/alsa-base.conf

get's overwritten in Natty in the file:

/usr/lib/pm-utils/power.d/intel-audio-powersave

I changed the line

INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
to
INTEL_AUDIO_POWERSAVE=false

Now Natty keeps the hda_intel adapter power_save settings as desired
