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): pulseaudio 0.9.15 How reproducible: 100% on this hardware Steps to Reproduce: 1.Install Fedora 11 2.reboot a few times 3.Listen to 25% audio output volume Actual results: Only front-left and front-right channels work. Expected results: Audio playing from all channels and speakers. Additional info:
Please run "pavucontrol", go to the last tab, and make sure you run PA in surround mode on the specific device.
