Hi, philsas
You need to switch off the audio description on your Virgin box - Home - Settings - Change Display and Audio Settings - Audio Description when available
However, be warned that when I do this there is a horrible buzzing on my Bravia, which is why I have come onto the Forum! I am hoping someone will tell me how to get rid of this buzzing which only occurs on my Bravia and not on another TV I used to test the setting!
Best wishes
