So, OOI, is it likely we have two HDMI cables that aren't compatible
with that Youview TV combo or could it be that the audio in on the
TV simply doesn't work (I'd not tested that before taking it up there
as it had only been used for Freeview before that).

Never come across that. I was surprised to find that an HDMI cable to a TV
from an after market sound card on a desktop PC had the audio too.

HDMI isn't just one easy standard, it can be quite complex with the differnt versions that have come and gone.

Check 1/2 way down the wiki page to versions.

I just looked at that to check my memory wasn't playing tricks...

"Transition-minimized differential signaling (TMDS) on HDMI interleaves
video, audio and auxiliary data"

The video and the audio are interleaved. Which means no cable fault
could mute the audio, but leave the video OK.
