Bingo! That worked, thanks a lot! 
How did you arrive at pin 11?
I wouldâve assumed pins 12+13.
Edit: Missed the âEN pinâ discussion above.
pin 10 is detecting if something is plugged in the 3.5mm jack.
pin 11 actives the speakers
I found out the pins when looking out to fix my audio problems when upgrading the kernel with @yatli help.
