Description of problem:
I have an Acer 6930 laptop that has 6 audio channels that are detected by alsa. When a clean install is done of Fedora 11, all of the channels work properly. After a time, just with a few reboots, the side, LFE, surround and center channels stop receiving output. This is the audio card info from lspci
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
The output from alsa-info is here http://www.alsa-project.org/db/?f=355bc4715fe422685dfc3a243a39967360458644
This may be alsa related, but I have used distros without pulseaudio for the sound server do not have any issues with the other channels.
Version-Release number of selected component (if applicable):
100% on this hardware
Steps to Reproduce:
1.Install Fedora 11
2.reboot a few times
3.Listen to 25% audio output volume
Only front-left and front-right channels work.
Audio playing from all channels and speakers.
Please run "pavucontrol", go to the last tab, and make sure you run PA in surround mode on the specific device.
