Comment 2 for bug 40218

OK, I figured out what was wrong, I have sound now. Going to the volume control panel, in the preferences I choose to display all controls (It initially had only "PCM" and "line in as output" ticked). Then I saw that "sourround", "center" and "LFE" were muted. It turned out that unmuting surround gave me sound back!
I guess the main sound channel should be "front" (which was not muted). So it seems there is a little error in configuration for this sound chip.
