These two items are related, right? Does it go away with a
32bit/extended kernel?

Here is one thing I don't like either. The layout and ordering of the
volume controls are unrelated to the routing and how the controls are to
be used.

Like this would make some sense:

[Front][Center][LFE][Side][Surround] [Master] ¦ [Mic 1][Mic 2][Line] ...

But like this isn't really helpful:

[Front][Front Mic][Front Mic Boost] ... ... ... [Microphone] ...

Where one 'Front' is the placement of the input jack (on the box) and
the other 'Front' is where you would place your speakers (if that is
what the port is used for.)

The layout and order is inherited from the ALSA driver who does not know
shit about the meaning of the labels, at least not much :)

That sounds really serious. You mean like a frozen machine or just
inexplicable silence?
