Match the codec used on your motherboard with the AppleALC supported codecs list and try all the possible compatible ones.
Sorry I just don't understand where/what I type in.
My motherboard codec is ALC1220, I found that on this page, but now do what?
In my config.plist I see 4 bytes: 02000000. Is that the text I replace, with something?

Yep, that's the page I'm on. Still have the same question.
search for your codec and try the numbers listed on the right hand side?

There's my codec, and there's the numbers on the right side.
So in my config.plist where it says "02000000" replace that with "0x100003", and if that doesn't work, replace with "layout 1" ? Am I understanding right?

You can delete the device properties for audio. Then use "alcid=xx" boot argument instead (xx=the id number). This is easier.

Okay, so to delete the device properties for audio, one would do that by deleting the following from the config.plist?

Once deleted, one would use "alcid=xx" how?

Yes.

Add the boot argument to config.plist > NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args.
 
Yes.

Cool thank you. Half-way there.
In boot-args the value is currently:
-alcbeta -lilubetaall debug=0x100 keepsyms=1 -wegbeta slide=0 -vsmcbeta

Where would I remove (xx=the id number) and replace with "alcid=xx" ?

Just add a space and "alcid=xx" to the end the current boot arguments. If you want to use alcid=1 it would look like:

-alcbeta -lilubetaall debug=0x100 keepsyms=1 -wegbeta slide=0 -vsmcbeta alcid=1
