Its a problem I have for about a week When speech pauses in a programme the background sound cuts out. I can’t find any settings anomalies.
Welcome to the Community and thanks for taking the time to post.
Sorry to hear that your BTTV box is playing up at the moment.
Have you tried a factory reset or checked for updates in the settings menu?
Let me know.
I did a full re-install. Seems to have worked but I have not had time to watch tv much since to tell if the problem is fully resolved.
