Sound on a Macbook Pro 5,5?

[crocowhile]

Ok just to be 100% sure this is what i have done.

Well, if we have the same machine and the same distribution it should really work. I just tried today and it was fine on my mac.

gg@ggmac:~$ sudo dmidecode -s system-product-name
MacBookPro5,5
gg@ggmac:~$ uname -a
Linux ggmac 2.6.28-13-generic #45-Ubuntu SMP Tue Jun 30 22:12:12 UTC 2009 x86_64 GNU/Linux

are you using 32bit by any chance?

EDIT:
Alright, I tried again. Doesn't work on mine either now :/ must be something wrong with the current snapshot

EDIT2:
wrong again. you must retain original folder "sound" in /lib/modules/`uname -r`/kernel. deleting the original folder is wrong.

Nope, Im running 32bit and i have the MacBookPro 15'

root@barry-laptop:/home/barry# sudo dmidecode -s system-product-name
MacBookPro5,4
root@barry-laptop:/home/barry# uname -a
Linux barry-laptop 2.6.28-13-generic #45-Ubuntu SMP Tue Jun 30 19:49:51 UTC 2009 i686 GNU/Linux

but from what i have heard 5,4 or 5,5 should not make a dif.

Edit:
Problem seems to be that if u remove the sound folder u are killing all the soundcore stuff, and without the soundcore thats why it throws up all the errors. I cant even load just snd

Then how come in your script you rm -rf that folder?

Then how come in your script you rm -rf that folder?

'cause it was a copy and paste of post #42. Now it's fixed. Sorry about that.

So, I did:

#delete the entire thing, just to clean up stuff
sudo rm -rf /lib/modules/`uname -r`/kernel

#reinstall the kernel
sudo aptitude reinstall linux-headers-2.6.28-13-generic linux-image-2.6.28-13-generic linux-restricted-modules-2.6.28-13-generic

#launch the script
./update_alsa.sh

#reboot and modprobe. Sound works

OMG its working... Thanx so so so much... been at this for 3 days since I got my mac on tuesday.

Edit:
Its a bit bugy but its working and my headphone jack is working.

[barryreid]

Have you by any chance been able to get the restart working. shutdown and all work fine. Just no restart.

I followed the guide a few pages back, but now I get "null output" in the sound controls, and modprobing gives me this:

james@james-laptop:~$ sudo modprobe snd-hda-intel

HELP!

EDIT: From my understanding, removing those alsa files was actually the wrong thing to do, right? How do I get them back? Reinstalling ALSA?

Ok here is a step by step guide on how to get it all working.

First thing you need to do is remove anything in your sound folder so we have a clean start, do this by running:

sudo rm -rf /lib/modules/`uname -r`/kernel/sound

Next thing you need to do is restor your original kernel files, to do this run the following command:

sudo aptitude reinstall linux-headers-2.6.28-13-generic linux-image-2.6.28-13-generic linux-restricted-modules-2.6.28-13-generic

After that you will be prompted to restart, Restart Now.

Once back in ubuntu run the folowing commands:

wget ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-unstable-snapshot.tar.gz
tar xf alsa-driver-unstable-snapshot.tar.gz
cd alsa-driver-unstable
sudo ./configure --enable-dynamic-minors  --without-oss --with-cards="hda-intel"
sudo make
sudo make install

Now reboot. Once your system is back up open up your volume control and unmute all the channels and make sure they are turned up.

Awesome! Followed the guide and got it working with kernel 2.6.31-3-generic.

Alas, still no headphones.

Thanks!

I've done all this but have no sound still. I get the Cirrus Logic stuff, but it was never muted in the first place...

edit: got it working! yay! now all we need is the headphone jack to work...

edit2: is there a way to compile alsa with midi support? I need it for audio production. If not, then I'll have to keep my older laptop around solely for that purpose.
