Public bug reported: balance does work. when i move the balance to left, sound is louder on the left but can still be heard on right and vis-versa.
i used the following test clip http://www.kozco.com/tech/LRMonoPhase4.wav left and right channels i hear on both sides, but the centre speaker test i only hear on the right channel. More info and asla-info dumps here. http://ubuntuforums.org/showthread.php?t=2171347 Happens on my Ubuntu 13.04 install, and also the boot cd from lubuntu 13.10. I don't have this problem if i plug the speakers into my laptop which uses alc663 chip.
