S1200A requires clean up before submission, beta available next week

Would beta -> release development benefit from additional testing of S1200A with different OS builds and hardware?
For example:
- Mac OS 10.13.6 - 17G4015, 17G3025 and compatible Nvidia web drivers; Mac OS 10.14
- IGPU, AMD GPU
- Motherboard BIOS updates

...debug log shows almost 300 codecs when the 1200A AppleALC has 4

Has this occurred since post #74?

Mac OS 10.13.6 - 17G4015, 17G3025

Mac OS 10.14

Yes

Have reinstalled macOS 10.13.6 (17G65) - let's see if that cures the issue with multiple codecs.

Also updated OS to 17G4015 with compatible Nvidia web drivers. (17G3025 is long gone).

Files (IOreg, TerminalOutput, screenshots, etc.) attached for 17G65 (as for post #91 and prior) and 17G4015 (new).

Did fresh install of Mac OS cure multiple codecs?

Updating to Mojave would normally require switching to AMD GPU for full acceleration. What works best for AppleALC beta testing - Nvidia with no acceleration (5MB) or AMD with full acceleration?

All working, expected. Thanks for testing and reporting all variations.

Not present in any of the recent debug logs attached. Codec reduction simply reduced compile time, kext size and length of the debug log.

Discrete graphics has no effect on AppleALC/S1200A testing.

S1200A release candidate: install attached, reply with new IORegs and Terminal output.

reply with new IORegs and Terminal output

Files attached for High Sierra 17G65 and 17G4015 for latest AppleALC and Lilu (post # 98). Mojave to follow.

Also, audio OK on wake from sleep.

Happy NY.

What is the best way to avoid multiple codecs when testing revised kexts? Does KextBeast remove old kext or replace with new kext? Post #74+ issues occurred after moving old kexts to Trash and running cVad's kext utility and then installing new kext with KextBeast.
