On PC version if you mute trough the button on bottom right the game the Television also gives a black screen.
Doesen't matter if you mute it before or durring the scene.
Also when I was playing I'm always reducing sound/music and it seemed like during the TV scene it has no effect (audio was extremely loud for me).
Hopefully it will help you a bit :)
