I am trying to receive audio on my Apple EarPods pro paired to my iPhone SE(legacy model) through the Roku app on my phone. I am viewing tv on a TCL Roku TV 7134X model 65S421. It was setup and successfully working last year through a TECBOSS KM20 Bluetooth 2-in-1 transmitter and receiver but now the Roku app says that private listening is not available for HDMI input cable tv. I went to the TECBOSS site for support but they don’t even list that product which I why I am posting here. Both my EarPods and the TECBOSS are successfully paired to my iPhone thru Bluetooth. I would greatly appreciate help with this problem. Thank you.
