Samsung TV Plus Euro News no sound

Hi. I have recently bought a new Samsung TV (QE50Q65C) which has Samsung TV Plus. The Euro News channel has no sound. I know there is a section of that channel called ‘no comment’, but this is not just that feature, it’s the whole of the channel that’s completely silent. All other channels are fine. I’ve turned the volume up to full so it’s not just being transmitted at a low volume. Does anyone else experience this please? Thanks
