Acer A315-51 Audio Issue

[srishcool]

I am trying to get macOS Mojave 10.14.5 working on my laptop. I was able to get to graphics, battery, brightness, keyboard and touchpad working. But was unable to solve issues with audio.My laptop has ALC255 with combo jack. I have tried using AppleALC with CodecCommander. I have tried every layout but none of them is satisfactory. I am currently facing these issues:

1. During boot, laptop abruptly shutdowns if headphones are plugged in. (Most likely due to HDAS to HDEF patch, but I don't know)
2. Static noise coming from headphones at random times. (most likely when laptop is idle or just after waking from sleep)(I tried using CodecCommander to solve this issue but laptop abruptly shutdowns after waking from sleep)
3. Mic through combo jack is also not working in any layout.

I have attached codec dump (through linux) and the EFI folder.
Sorry if DSDT or EFI folder is a mess.
