I have installed today Windows. To my surprise, the Line Out jack doesn't
work, no matter what output I would choose in Windows (2ch,4ch,6ch).
Surprisingly, the Line in works (in 4ch), but I can only hear sound in the
right speaker & the sound in the left speaker is very faint.

I took is as a hardware problem of the MB and left it as is (I left the
speakers in the Line in jack).

Sometime later I booted into Linux. Playing through the filesystem, I
don't know what made me choose Play from the context menu over a file.
Surprisingly, amarok started and I got sound in the right speaker.
Amaizing improvement.

I've continued my reasearch in the configs and discovered, after my recent
playing in them, that "Duplicate front" and "Line in as surround" were
checked. Unchecking turned off the sound. It was kind of obvious that I
would get sound through the Line in jack with these 2 selected.

I must also add that the Line In (Line is as surround) is badly balanced
(as in Windows) - I suspect this to be a hardware problem, I'll research.

It turned out to be a hardware problem (Front panel was incorrectly wired
to the motherboard).

This bug can be closed. Sorry for all the fuss, but I couldn't have
thought about an incorrect wiring (this has been done by a 'pro').
