before my switch can’t charge and can’t connect tv dock, and then I changed m92t36 chip and pi13usb chip, now charge and tv mode no any problem, but hands mode no any sound, I use headset no sound too, tv mode can normal work.
I want to know like this problem form where? m92t36?? thanks in advance

HDMI becomes its Sound directly from the Processor (Spidif) so thats the reason why you have sound with the dock

Issue should be Realtek Audio codec on the back side
