Thank you very much Johan for your thoughtful and detailed answer. Much appreciated.
I’m back home after the long weekend tomorrow and will try your suggestions and sort out which cable I need to buy.
I didn’t hear the TV before but was given to me by a family friend who assured me it was working when his daughter was around (I get the feeling she played it LOUD), but he couldn’t help with the cable situation.
Once again, you’ve really helped me focus on what’s needed, so will report back when I’m annoying the nightbours!
