Intermittent sound on multicast chsnnels

[Photoloz]

I'm having real issues with intermittent sound on all multicast channels with my 4k bt box. I've changed HDMI cables and ports but problem persists.  The box isn't a new one and these problems have only recently started

You mention changing ports, but how is the Youview Box connected to the router (BT mini connectors or direct ethernet)? If powerline adapters, try testing with a direct ethernet connection first, as powerline adapters can become faulty over time.

Thanks Stefan, our box is connected via adaptors so will try direct Ethernet and see. Already had soft reset on machine with no change so this might be a useful option. Will advise outcome. Thx

Just to advise that your solution worked perfectly! We required a 10m cable that's now hidden under carpet edge but no sound issues at all. Thanks
