Ok guy's got my ALC883 sound working too...

used the driver here: http://www.mediafire.com/file/teqcid...leHDA.kext.zip

Apparently it's a 3.1MB file as compared to the stock 1.2MB file...

This link is where I got my info....
This guy in the post is talking about 10.5.6, but I've got working sound on 10.5.8 using this exact driver. Odd thing is, i had it in 10.5.7 before the reboot...
