How can I get tv in 2021 2208d's to play tv audio through the trailer's on-board stereo system? It does not appear to be connected. Tried several things but cannot get tv audio into trailer stereo.
You should have the same Insignia TV/Connex stereo as my 2020 Minnie, and the TV is connected to the stereo via HDMI cable. To get TV audio to the stereo, press the ARC button on the Connex remote. Prepare to be underwhelmed!
