I've turned the TV off and on. I have switched to other channels. My Spotify works just fine. I've been watching other shows with music earlier tonight.

I don't use additional hookups / speakers / receivers with my TV.

We use an antenna / rabbit ears. We do not have satellite or cable.

They are only muting music on this show.

Commercials with music work.

Edit

Added that we use an antenna / rabbit ears and do not have cable or satellites.
