I have only one cat6 behind my tv if I want to send audio to the speakers can I place a switch behind the TV and still send the audio back? The TV is using the one cat6.
You will need an optical Balun or an ARC Balun . (Just depends on the inputs you in the amp ) There is certain baluns than can pass Video, Audio, Network and IR.
You have one cat6 but it being used for net work ? If you need the network because WIFI is weak maybe a audio out optical 3.5 rca ect. To bluetooth transmitters If your receiver dosen't support bluetooth add a bluetooth receiver that's if your equipments not far away from good luck Do it for head phones all the time tv sound to bluetooth
