Hi, I recently bought a macbook pro 13.3 inch.
and I installed ubuntu 10.10 RC on it.

By following wiki guide:
https://help.ubuntu.com/community/MacBookPro7-1/Lucid

Almost works fine.
But despite add "options snd-hda-intel model=mbp55" or not, there is no sound
I've checked alsa-mixer that "PCM" and "MASTER" are not mute.

Does someone has the same problem? or any suggestion?

P.S:
there is an unfinished wiki for maverick on macbook, but I cant not wait :(

And dmesg attached.

add dmesg.log and
HDA part of `lspci -kQ` are as below

00:08.0 Audio device: nVidia Corporation MCP89 High Definition Audio (rev a2)
Subsystem: nVidia Corporation Device cb89
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel

use model=auto I got the same situation.

but I found a patch for deviceid=cb89
http://www.spinics.net/lists/alsa-devel/msg38369.html

and I'll patch kernel to try it again.

P.S:
There is a same bug report here:
https://bugs.launchpad.net/bugs/647389

but he said he solved the issue by followed:
https://help.ubuntu.com/community/MacBookPro7-1/Lucid#Sound
this does not work for me although.
