Someone had asked if there was a difference between the alsa-driver 1.0.19 patch and using the 1.0.18 alsa-base that's in the repositories with the mbp3 set as model in /etc/modprobe.d/?
I'm not sure if sound quality or anything improved.  Was it supposed to?

Also I've had my sound muted for the past 2 weeks or so and now when I
unmute it I still have zero sound.  I was going to re-follow the wiki to
patch alsa 1.0.19 and see if just re doing it got sound working again
but does anyone see any benefit in just trying the already patched
1.0.20?

I've applied it to 1.0.20 tree btw.. It works fine on Arch Linux with a
few exceptions I've mentioned 2 comments earlier..


So if I can/should try 1.0.20 where is the already patched download for it?

Also if this new version is in Karmic will it make its way to Jaunty
backports?  I wonder if my sound broke because of some repo update while
I had the patched version of alsa.

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.
