I'm using Arch Linux and have a Macbook Pro 5.1.. I was trying to get
your patch working for the whole day... (since alsa-driver comes with
kernel26 package in Arch Linux) any way, i was told to compile the
modules instead of compiling the whole kernel which saved me loads of
trouble..

Your patch seems to work fine for me.. But there seems to be some stuff
that need to be polished:

1) i don't notice the difference btw. 2 and 6 channels

2) adjusting master, pcm levels are acting weirdly. if i lower master i
can't hear anything when it's near some value of %50.. same for pcm..

3) sound splutters when too high which i don't remember in OS X..

but your work made my day (today is my birthday btw) as a great
present.. i've deleted OS X completely from my computer and am trying to
configure non-working stuff.. thank you guys!

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.
