7480 or 4380 or 3480?

With patched SSDT-xxx.aml's  for USB, you can disable the port limits patches in the Config file.

I see you're using layout-id=21, is that better audio than 13 or 56?

InsanelyDeepak added layout-id = 14 with subwoofer, have you tried if that works?

Sorry! 7480 like a topic name, but i add wrong name the zip :) 

I correct this problem.

 

All works, no need other patch or layout ID.

Sound is perfect, headphone perfect, all USB port perfect with type-c. 

I not tested other layout ID.

It's already commented out so not an issue. You could remove it if desired, but not the Audio part. Leave Inject = No or try Inject=0
