[alsa-devel] alc262 - hda intel driver - power save not working

Hi,

Have been working on this to get the power save option to work for ALC262 using intel hda driver. (ALSA 2.16v, Kernel-2.6.22.18-1)

Once i load the driver, the power_save_controller shows 'y' indicating its enabled and power_save value is set to'10' Still i dont see the driver going into d3 state when there is no playback or capture happening. I also made sure that i play a file, close the player and mute the controls. I wait for 10 seconds and still see the power consumed is the same whereas I expect the power to come down.

Please help me with more clues as to what i could be doing wrong or missing here. Any clue will be greatly appreciated as i am needing to resolve this ASAP.
