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

 

1.  I don't really hear sub from macosx either so not sure about this
one still.  I do think we *should* hear it but if it isn't in macosx not
sure what needs fixing.

2.  I don't have this issue, yet.  I turn on and shutdown twice a day
and sound is at levels I set everytime.  Could be an affect of something
other package you installed?

3.  I don't have this issue either.  As #2 maybe you installed something
that is effecting it?

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.
