Thanks man I used DPCIManager to dump my DSDT and used that with ssdt time to create the patches now audio works.

 

for anyone with the same problem this is what I did,

used Aida64 to verify my audio codec set my layout id to 12, 

used DPCIManager to dump my dsdt.aml and used that to fixhpet 

opened patches_oc.plist in ProperTree copied the add entry under apci add copied it to my config plist created a new child and deleted everything under patches and replaced it with the ones from patches_oc.plist saved and rebooted... now I have audio.
