The control status with the FIX-UP (and the new pin config) is:
Master: controls the hp volume
Front: dummy
Surround: dummy
Center: dummy
LFE: dummy

The speaker was moved to line_out, so cfg->speaker_outs == 0.

the mac book pro has a built in speaker, a built in microphone and two
jacks. One is a spdif output and headphone. The other one is a spdif
in and a line in.

The controls should be:
Speaker, Microphone, select builtin mic/line-in . I am not sure if
there should be two different controls or one control and one select
switch for the mic/line-in. Currently I also have IEC958 to turn on
the spdif output.

I don't have any spdif equipment. I also don't have an external
microphone, but I am sure I can get one for testing.

Right. I love that :-)

I will give it a try latter on.
