Actually this is equivalent with the change in the upcoming 3.2
kernel.  The whole static configurations for ALC269 have been already
dropped, so it uses model=auto as default now for ALC269.

But, since 3.1 kernel is broken for some ALC269, I'd need some fix for
stable kernel.  Did you try my patch with 3.1 kernel?  It's not in the
upstream, but should be applied exceptionally as a regression fix (if
it really works).


thanks,

Takashi
