nyolc8 got a reaction from gautamaurya in Need help from an AppleHDA professional for my ALC662
You have an ALC883 not an ALC662. It's clearly says on the top of the codec_dump. You need an AppleHDA for ALC883.
Use this DSDT: Link
And try this kext: Link (use only the AppleHDA.kext file from the package, don't use the extra folder)
