Did you start fresh and follow the guide from start > finish? I've used this guide 5+ times and never had an issue.
Are you installing Yosemite or Sierra?
Delete all files in /EFI/CLOVER/ACPI/Origin, reboot into clover, press F4, follow patching guide again.
Make sure you use the correct version of Mac iASL, as well -- some of the newer ones don't support list ACPI 5.0 in preferences, so find one that does.
If you have Audio issues after that, take a look at patching your DSDT with a native [vanilla, unpatched] AppleHDA.kext.
**edit-----
^^ this ^^ means if you've already done the damage, you're going to have to start with a new, fresh install of the OS - and we've all been there multiple times.

THIS ****** post might help - I know there's a guide on one of the forums [try them all, there's a ton] but you can find it on your own.
-- All I can say about this method is that I had originally messed up my Yosemite's audio somehow, then installed the Sierra Preview on a separate partition. Once I used this AppleHDA method, my audio was enabled on both partitions.
