It's pretty clear why it's not working... It's totally different PIN
assignment :/ It seems that you have
2  Mics at other PIN's than I and other folks have (we have one). Are
you sure that this is MacBook 5.1?
When was it purchased?

Bug description:
Reporting this bug for another user...

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.

This bug is confirmed by several users, see the additional information attached.
