MacbookPro 5,3 no Sound 2.6.36 kernel

Hello everyone,
I just put arch on my macbook pro (net install) and i can't seem to get sound to work.

I have tried everything i could find on google,

i have changed my modprobe.conf to contain

options snd_hda_intel model=MODEL
where MODEL has been auto, imac27,mbp,mb55,mb5t,intel-mac-auto

I have built and installed the edited kernel from:
https://bbs.archlinux.org/viewtopic.php?pid=875152

I have installed the newest snapshot of alsa-driver i could find from advice from an Ubuntu post.

I installed pulse audio hoping that would change something.

i made sure alsamixer levels were up,
i tried alsaconf, no cards found.

But alas, nothing is working.(headphones or speakers)


Here is all the info i hope is needed:

aplay -l:

Re: MacbookPro 5,3 no Sound 2.6.36 kernel

Should i just try a kernel downgrade and see what happens?
Any recommendations for versions to go to? Would that do anything?

Would i be worth un-net installing? Go back to the 2010 snapshot? I know the newest versions of kernel also messed up my wifi drivers did it do the same to sound?

Thanks again for all the help

Re: MacbookPro 5,3 no Sound 2.6.36 kernel

Ok, I just reinstalled to 2.3.33 and the sound works right out of box. All i had to do was alsaconf and it found the correct card. It doesn't work through headphones, but i don't much care about speakers.
I guess i will stick with this version unless anybody has any fixes for the newer one.
