Sound and picture not in cync

[Fishnerd]

Most annoying trying to watch the final round of the British open. Only purchased the sky sports for this final day.  Delay , sound and picture all wrong?

@Fishnerd This is a known issue that Sky have been trying to resolve for a couple of months.  Have a look at this comprehensive thread

To save you having to wade through the entire 30 odd pages the recommended temporary solution is to change your Audio Settings to PCM or Passthrough.  (Settings > Picture & Sound > Sound)
