Bug Description
Since upgrading to karmic this week, I notice a swelling, high-pitched noise from my speakers when no audio is being played.
It sounds similar to a camera flash charging, until after a few seconds, a loud "pop" sound comes from the speakers. Then it starts over again.
As soon as I unload the snd-hda-intel module, the phenomenon stops. I can also interrupt the "charging cycle" by producing sound (eg. hitting the tab completion in a shell, or play music).
If one could provide a comprehensive list of snd-hda-intel's module parameters, I could try them out.

I found this entry in /etc/modprobe. d/alsa- base.conf :
# Power down HDA controllers after 10 idle seconds
options snd-hda-intel power_save=10
When I remove it, the noise is gone.
