Ubuntu 10.10 RC no sound on Macbook pro 13.3"

changsijay

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.

changsijay

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

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?

changsijay

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.

changsijay

Still no sound, after patching kernel.

mfillpot

I was really hoping that the patch would work for you, but it does appear that the alsa libraries still do not have the required instructions to handle your sound card. The best recommendation I can give is to follow up on the bug report so the ubuntu developers (who know more about the core systems than I do) can network to get the issue resolved for you and future users.
