I can try and have a look, but if you're telling
me that the above are irrelevant, then it must have been
something else;
luckily I saved 2.6.28-rc9
So I can go ahead and load that kernel, and see,
without adding any config options, what it looks like.
(the problem is there might have been some more commits,
that might have affected that since 4 days ago.);
hence the change from "front" to "Speaker"
on the mixer itself. making this a lost cause.
