I recently bought a sound bar from a third party...really nice sound bar with HDMI hookup. I can not get the TV to play sound through the bar at all and now can’t get the TV sound back on either. Roku not answering their phones. Can anyone help ?
If you want audio to go the soundbar from the tv you have to plug the hdmi in the input labelled ARC. The Roku tv has it, but the SB may not. In that case you use optical cable to send the audio from the tv to the SB. Go into the Roku tv menu refresh the hdmi devices attached to it:
settings> system> control other devices(CEC)> search for cec devices>
