I had a little free time, so I decided to play a little with alsa. I
copied the mic verbs from the old model to this new one and it seems
to be working fine. Here is the patch for that

Now, the only 'broken' thing is jack sensing, it just mutes front, but
not LFE. I guess this is an easy to fix issue.
