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.
