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.

Hi!

 

I test the layout-id=14 and sound same good.

Internal speakers perfect, mic perfect, headphone jack perfect!

There is no difference like layout-id=21

Also test HDMI. HDMI work but no sound in TV.

USB installer not work my old EFI folder, but i fixed this. (Not rechognise installer USB)

Upload new EFI folder. Almost all works... (HDMI audio not only)

See my first post.

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

Im not use HDMI, only testing.

If anyone find a solution, post.

 

Thanx Again!
