Re: [alsa-devel] hda intel - power save - need more help

I verified the value of /sys/modules/snd_hda_intel/parameters/power_save to be 10.

How can i ensure that the analog switches are off? Through Kmix?

I checked on these articles on powertop...i manually set it the value to

for *POWER_SAVE_DEFAULT but still don't see any power saving...

Check whether it's really set to 10 in /sys/modules/snd_hda_intel/parameters/power_save.

Also, the power-save is turned on only when all analog loopback switches are off, e.g. Mic Playback Switch or Beep Playback Switch must be off. Otherwise the analog part must be powered on.
