Hello. The T.V is connected to my Sky digital box and I think the input to soundbox was correct. It only has an optical input on back of soundbar.
Yes, I think so. Sorry but not very good at this stuff. My son-in-law usually does this for me but he is not here just now!
I tried again with the optical cable but still no sound. I will have to get the audio cable you suggested and try that way. If that doesn't work I think the T.V may be the problem. Thanks for your help anyway!
