Ubuntu 10.10 RC no sound on Macbook pro 13.3"

Link to this post 06 Oct 10

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 :(

Can you run "sudo lspci -kQ" and copy the portion referring to the Audio Controller here? Your issue may be be a case of an alternate audio controller being used and this will tell us exactly what is in your system.

Thank you for all of the information.

I have reviewed the list of available models at http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt and the mpb55 appears to be the only model for macbooks. Have you attempted to change the model to auto to see if it will autodetect and use the best drivers?

Link to this post 07 Oct 10

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.
