Bug Description
In an attempt to maximize power saving on my laptop, I ran powertop and it suggested using this module option:
options snd_ac97_codec power_save=1
Now that this option is enabled, every time some audio is played there is a loud pop from my speakers before the audio begins.
Is this the expected behavior? It is very loud and obnoxious. Is there anything that can be done to remove or soften this pop when and still be able to use powersave mode?

There is also a much more subtle pop when the sound is done playing, or when the last audio application is closed. This one doesn't particularly bother me since it is barely audible, but if that pop could also be removed, that would be awesome.
