I assure you my /s/l/e is clean, no modified kexts at all

 

EDIT: i can confirm the DSDT is working for patching hdas to hdef as without it or the patch no sound devices show but with it i get sound devices just no audio out of any of them.

no output at all.

OK. Delete CodecCommander.kext and try again. With patched DSDT because your HPET interrupts are incorrect.

i don't have a codecommander.kext on the last testing i did i had no acpi patches, just the 2nd dsdt that maldon posted and tried all layouts. still no sound though.

And also post latest DarwinDumper and IOReg with latest DSDT provided by @MaLd0n.

Sorry! But i don't know what happens. It should work! But i also see a lot of audio errors in kernel log. Suggest you to make clean install with your EFI folder!

audio errors depend on what layout i'm using

 

i did a clean install yesterday, but didn't make no difference.

Sorry then I don't know how to help you. Maybe you need custom resources made from your codec dump.

Alienware Alpha & Alienware Steam Machine ALC3220 (ALC280 variant) 

 

codec-id:

0x10ec0280 

 

layout-ids:

11: SPDIF-OUT

 

macOS: 10.12.4 and newer

All outputs (no input, only spdif output)

No special patches

Hi vandroiy2012,

 

Could you please add this alienware alpha's alc280 config to AppleALC repository?

 

BTW,alienware alpha has only one optical spdif out and no input,i've validated my config working.

 

BRs,

 

Ganxiao
