I wonder if someone can help me. I tried setting up my Dad's system a couple of weeks ago and almost had it all running nicely. He is now back from holiday and I will be going round there this weekend to finish off. The problem I found was getting audio from his new Humax box. He has an old Wega LCD which doesn't have hdmi. I bought him a component switching unit which has coaxial and analogue audio connections. I set it up so that component runs from LCD to switch box and then component from switch box to Humax and another to HDD dvd player. He has a Sony home theatre dvd box which is the amplifier. I connected the dvd player to the amp with coaxial. Picture and audio fine. The Humax doesn't have coxial so I ran optical from it to the amp. No sound. Do you think this could be because the switch box only has coaxial and analogue? I'm going to take some RCA cables over there on Saturday to test my theory.
