I tested the test board here (which has 3-stack + front-panel) and
found that the surround doesn't work here, too.
It's because the wrong initialization sequence when switched to the
6-channel mode.  After fixing it, the surround seems working well with
6-ch mode.  The patch is below (already committed to CVS).

I guess the wrong pin control assignment or the unmuted amp volumes in
somewhere in your case, too.
