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

 

Any way to get it automatically working with MBP5,2??  I could probably
manually type in mbp5,1 for the model and get it to work but would be
good to have it auto if there are otherwise no differences.

If it helps I've attached cat /proc/asound/card0/codec#* > mbp5,2.codec

and also ran the alsa-info.sh script whose output is here:

Let me know, and thanks!

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.
