Chances are that the current TV show, music, or platform doesn’t have sound.

If that’s the case, you should switch to an alternative broadcast or source of media and check if the audio is going to appear there.

You can attempt it on platforms such as YouTube, Netflix, Hulu, Spotify, or whatever is available on your TV.

If it is a music player app, it will most likely have a volume controller on its own. Make sure that the audio is increased from there also.
