Hi, hope someone can help....I have an issue with severe sound clipping during programme breaks or as a programme is ending on broadband delivered channels. For example if I am watching a film on one of the sky channels just prior to the end titles (last few scenes of film) the sound will start to clip badly. This does not happen on any freeview channels. I do have my TV connected by an optical connection to a sound bar, but have no issue if using Netflix or players - just the live stream channels. The sound clipping will stop as the next programme starts - it's rather annoying!
This is a known issue, see here:
