[Bug 337314] [NEW] Left speaker doesn't work, controls mixed up on Apple MacBook[Pro] (5, 1)

 

Public bug reported:

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.
