Hi there, having kind of a strange problem with my 50LB674 webos based tv, in audio options i dont have the option to choose as audio output TV Spekaer/external (so it automaticly switches to the Logitech when turned on) i can only choose one or the other. On my old LV579 it worked just fine. I have seen several videos online where the option was availible in web os but on my tv it does not seem to be there. Any ideas why this might be so? Oh and its connected with an optical cable. Cheers
