My (not a smart TV) Samsung flat screen is connected to my Roku Express via HDMI. I’d like to use headphones connected to the audio out RCA jacks on the TV. Or, I have a blue tooth streaming device that can plug into the RCA jacks. I have tried various audio settings on both the Roku and TV but no sound from the jacks.
I can’t try the jacks using cable or antenna reception (vs Roku) because neither are available.
can’t figure out how to get sound from the RCA jacks.
