I am trying to get wireless headphones to work in my ht system. Have Vizio P tv with Onkyo 676 AVR. All inputs go in to receiver with hdmi out from receiver in to arc on TV. I have non Bluetooth headphones connected via tv out optical to headphone transmitter (I have tried the analog output as well). They work when receiver is off (pass thru) but once receiver is turned on they quit working. I have tried turning tv speakers on off and auto as well with every possibility of arc and CEC I can think of on both avr and tv. Can’t go to Bluetooth as I am trying to get these to work for hardof hearing spouse which will eventually turn in to sound in to hearing aid. Also don’t want to use zone two as it only outputs analog Thanks in advance.
