Please help, I have just purchased a Panasonic sound bar and have connected to my toshiba 42xv555d tv through an optical cable and can't get any sound. My sky box is upstairs and sky works through a magic eye. The only picture I get is sky in atv mode. The optical cable only works in dtv. The sound bar doesn't have HDMI slot either. Is it something to do with sky and rf out, atv. Can't run a cable from sky optical to sound bar either as it is up stairs. Stuck
