[alsa-devel] [RFC PATCH 1/1] ALSA: hda - add a timer to find and suspend idle codecs

Hi Jaroslav,

I don't want to change the control interface of power saving, for compatibility consideration.

Is it possible that HD-A still uses this "power_save" parameter, but let kernel
send a notification to the driver module? Need to change the generic implementation
of module parameters?


Thanks
Mengdong
