Title:
Static sound on Left Channel with hda-intel STAC 9221 A1

Status in Linux:
Unknown
Status in linux package in Ubuntu:
Fix Released

Bug description:
Binary package hint: kernel-image-2.6.27-2-generic-di

I get static from only the left channel even on a clean install of
8.04.1. Now I have upgraded to 8.10 and I have the same issue.

I have a dell dimension 9150 with codec stac 9221 A1 that loads hda-
intel.

I found a workaround to my problem which consists of simply rebooting
the machine, then the static is gone. But when I shut down and
restart, the static is back. It is a slight pain booting twice every
time to get acceptable sound.

I've tried different programs, different devices
(pulseaudio/oss/alsa), lowering the sliders in the volume control but
with no luck.

Should I include any other files/info?

Thanks
