Yes.

In each case whatever you change something.  I have to check the codec
state whether the surround volume really does the right job as
expected. 
Also, we need to check the state with and without the code in
patch_sigmatel.c, with and without HP plugged.

Also, try the original 1.0.16 and get alsa-info.sh as well.

Yeah, there are lots of required tests.  That's why it's so nasty to
debug this kind of problem...

This can be found from alsa-info.sh.
