I have a Samsung TV (UN50-J6200AF - bought in 2016) connected to an Onkyo Receiver (TX-SR393 - bought in 2019) with ab HDMI cable. Also attached to the receiver is a Fire Stick and a set of 5 external speakers. The TV is set to output to the external speakers. All is working fine. I recently connected a digital OTA antenna to the TV with a coax. I want the antenna sound to go to the receiver and external speakers.
I have communicated with Onkyo and they suggested an optical audio cable from the TV to the receiver or an HDMI from the receiver to an HDMI-ARC on the TV. None of the HDMI connections on the TV are marked ARC. Are they that type and just not marked?
Of these two options, which is better? I have not tried the optical connection because I don't currently have the cable.
