[Bug 417302] Re: [karmic] cracking sounds before sound playback

[chelz]

Hi I just did an upgrade from 8.10, to 9.04, then to 9.10 and I'm
experiencing this, as in playing audio would begin with a crackle almost
always. I didn't experience any high-pitched noises or crackles
periodically, as mentioned in other bugs that suggested the "comment out
snd-hda-intel" fix, only when playing audio.

Commenting out
options snd-hda-intel power_save=10 power_save_controller=N
in
/etc/modprobe.d/alsa-base.conf
then rebooting gets rid of them.

I would like to supply any info about my system that might help in the fixing of this issue. Here is something that might help:
