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

I would prefer to create a sysfs file to track the writes rather than using this timer hack.

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
