I am trying to solve audio problem on my Acer V5-573G, Haswell, ALC-282, Big Sur, OpenCore. Everything works except audio. I've tried everything, detected PCI address by gfxutil, tried every layout for ALC-282, alcdelay, fixed HPET..... nothing works.... I am not sure, but it could be related to the fact that there are two audio devices and that AppleALC cannot do the job because of that. Attached is screen shot from DPCIManager. Could anyone give me a good advice how to solve it?

Hi. I have the same audio codec on my HP laptop and mine works using layout-id 3 and AppleALC.kext. What layout-id are you currently using?

Also 3. But I tried with all layouts sugested by AppleALC. (3,4,...,127)
 
Any suggestion?
 
It's Haswell, i5-4200u, 8GB RAM, FHD... I really tried all I could... SMB is set to zero. The rest is at it is on my laptop.

please read the faq for proper hardware profile setup:
 
not sure why you are listing 2 audio sections for?

One is for HDAU (HDMI audio) and another one is HDEF. I’ve added HDAU today. Nothing changes if I remive it. And I’ve already read those FAQs. Do you aim at anything specific?
