snd-hda-intel powersave option and "CLICK" from speakers

this is probably a duplicate, but I've been encouraged to file a bug with specific hardware information rather than 'me too' ing on another bug.

Basically, clicking from speakers all the time, fix described in Bug #381201 does work to fix it, at the expense of some battery life apparently.
