Public bug reported:
Binary package hint: pulseaudio
After a clean install my audio channels are incorrect. I go to Sound
Preferences Hardware tab and select Analog Surround 5.1 Output and click
Test Speakers. Front left is back, Center does not work at all, Front
right is rear right, Sub Woofer doesn't work at all, rear speakers sound
in front. It was working fine under Maverick.
