With 2.6.21-rc6, surr and center/lfe remain silent,
regardless of alsamixer
setting. When I patch ad1986a_3st_init_verbs out, it works.
Another related bug is above:

I guess writing 0xb000 is not enough, as the lower 6 bits
are gain value. Or
does the gain get applied somewhere else?

Well, I am not sure how to read the specs:
0x0f Chooses the mic inputs betweeb the MIC_1/2 and C/LFE
pins. Contains the
mic gain boost amp.
0x10 Chooses the line in inputs between the line in,
surround and MIC_1/2
pins.
I think with those NIDs you actually select between "I
want line in" or "I
want surround out" and whatever.
I remeber having troubles capturing sound via mic in or line
in using audacity
alsa driver. I only managed it with audacity oss driver
(with alsa oss kernel
emu). I guess this is related to wrong setting of above
NIDs?

This works, I get sound.
