Indeed i forgot about posting my HW specs,
there my ioreg and my dump.txt uploaded from dropbox:
My boot loader is clover EFI and this is a
MacBookPro 8,1 intel i3 1,4GHz, my mb is a x201e. (laptop mb)
My sound chip is HD Audio controller alc269vb, codecID 0x6902EC10
Yes i tried to edit my headphone node in the NodeToPatch section in the info.plist but nothing..
But i ve heard that voodoohda didn't support auto-switch as applehda, did it?
Hopefully this will help you more finding a solution
