For me it aint working also. 75PML9636 with 2 TAW6205 speakers. I connected the 2 speakers to wifi, updated both to latest mcu. I can sync the sound with the play-fi app on the TV as TV audio and as surround. Both working well. However extending ambilight from the TV to the leds of the both speakers won’t work. After pushing the syns button for 3 seconds the LEDS on the speakers should turn yellow to tell it is in sync modus. I just can’t get them to that for both speakers. Hardware failure or am I missing something?
