What's that noise on 433?
 

Was watching a movie-channel earlier between two movies.

They showed a preview for tomorrow's Premiership+ Game Charlton v Arsenal.

There was a dreadful noise coming from my surround-sound system and the TV speakers.
After the preview, the sound returned to normal.

I then went to channel 433 and I got the same noise during the Season Ticket advert.

Anybody else getting this?

I hope they fix any technical problems before tomorrows game.
