Not sure if this is a Kodi issue or Add-on?
It only seems an issue for certain series (eg The Expanse) whereas others are ok.

Started checking which shows had the issue.
It seemed literally every second one did.
So I tried going back to one that didn't a second time and found sound was there.
Further testing indicated shows without sound first time will be sorted by backing out and coming back in.
A bit weird but I guess I can deal with this.
