was audio working prior to replacing with the new patched DSDT/SSDT?

Repair permission and rebuild cache to see if this helps.

What version of BIOS are you currently on or version of BIOS the DSDT/SSDT extracted from?

The audio is working when I use BIOS 1.5.3 and your E7x70_Sierra.zip.

After I update BIOS to 1.12.3, the macOS could not find wireless, ethernet adapter and audio.

And then I try to downgrade to 1.5.3, it show me:  ME Firmware EndUpdate Failed Error: 0x00002200.

 

My current version is 1.12.3

DSDT/SSDT was extracted from 1.12.3

Working: sleep, wireless, bluetooth, ethernet adapter

The audio still not working, after repair permission and rebuild cache.
