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

 

yea redid and its working again. 
I have every vol. slider at max.  The master then adjusts the vol but from about half way down the vol is too low to hear.  it really is just from halfway up that is adjustable.  

Also where could I try 1.0.20 with what patch?

any chance of this getting into a package so other updates like to the
kernel don't keep making us have to re build this and install 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.
