Thanks for the patch alex.

I appear to have a slightly different chip than most other MBP 5.2
owners but your mb5 model works quite well. Except for the background
noise on the headphones, which some other guy also complained about
earlier. In Windows the PINs are totally different from the alsa
configuration and there is no noise. I tried to replicate this
configuration in alsa but got no sound at all. Surround/LFE/Center are
also dead.

Anyways, when pushing this upstream maybe you can also merge the
attached patch to recognise my chip.

Its from a 17" MBP from about July 2009.

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.
