I've been trying to connect my TV to the Wiim using the optical input but keep coming up against a volume issue. The TV is a lot quieter than streamed music so I'm having to crank my amp up way higher than I should need to. Is this likely to be a Wiim issue or TV issue? Any fixes? Pretty much the only thing I can change on the TV menu is to set it to PCM which is the only way I get any sound at all.
