The TV is set to have the audio output as the soundbar. The soundbar does have audio if I select the soundbar from the Roku TVs home screen. I used to have this setup on a sharp Roku TV and it worked fine using the TV as the audio output.
Make sure the Soundbar is connected to hdmi-arc, and then go into the TV settings update its cec devices.
settings> system> control other devices (CEC)> search for cec devices> ok
Without, me making any changes to my devices the Westinghouse Roku TV is magically playing through the soundbar now. TY for your help.
