Hi Everyone!

I'm running a MacBook Pro 17" 5.2

I have used the latest patch with both the -p1 and -p2 options and in
both cases no sound comes out of the computer speakers. I do however
have full 5.1 sound as played by this video
http://www.youtube.com/watch?v=6H6a-qN9fYk coming from the headphone
jack.

Any idea why my speakers are not working at all?

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.
