Bug Description
Binary package hint: kernel-
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/
Should I include any other files/info?
Thanks

i can confirm this bug. rebooting does fix it, but sometimes it takes three or four reboots until the static goes away. it's a temp fix, but something more permanent would be nice.
it seems linked to the HDA Intel chipset, although I do not have this problem in Fedora or PCLinuxOS.
