No Audio Going to TV's via Thor Petit HDMI RF Modulator

[Ervin Johnson]

I am using a Thor Petit HDMI RF Modulator to send video and audio to the TV's. When I play a video on Youtube, the audio goes to the TV's just fine, but when I send the audio source, (Soundcraft UI24R Digital Mixer) through OBS, I get no sound on the TV's.
