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.
