Comment 4 for bug 440540

Very good idea ...

I read the alsa/powersave.txt kernel doc and found out about power_save and power_save_controller. So i tried this:

First disabling "power_save" (did not fix it) ...

 cat /sys/module/snd_hda_intel/parameters/power_save
   => 10
 echo 0 > /sys/module/snd_hda_intel/parameters/power_save

Resetting power_save back to default:

 echo 10 > /sys/module/snd_hda_intel/parameters/power_save

Next I checked power_save_controller and disabled it:

 cat /sys/module/snd_hda_intel/parameters/power_save_controller
   => Y
 echo N > /sys/module/snd_hda_intel/parameters/power_save_controller

... and yes! that fixed it!!
