AC97 codecs. In this mode, the power-mode is dynamically
controlled at each open/close.
The mode is activated by passing power_save=1 option to
snd-ac97-codec driver. You can toggle it dynamically over
sysfs, too.
The mode is activated by passing 'power_save=X' to the
snd-ac97-codec driver module, where 'X' is the time-out
value, a nonnegative integer that specifies how many
seconds of idle time the driver must count before it may
put the AC97 into power-save mode; a value of 0 (zero)
disables the use of this power-save mode.
After the snd-ac97-codec driver module has been loaded,
the 'power_save' parameter can be set via sysfs as follows:
echo 10 > /sys/module/snd_ac97_codec/parameters/power_save
In this case, the time-out is set to 10 seconds; setting
the time-out to 1 second (the minimum activation value)
isn't recommended because many applications try to reopen
the device frequently. A value of 10 seconds would be a
good choice for normal operations.
See Documentation/sound/alsa/powersave.txt for more details.
