I have no audio going to my ht-ws1 soundbar. Original wiring was stb hdmi to samsung optical out to soundbar. the second way was stb optical to soundbar. the original set up stopped working after a cable tech installed phone to the same cable outlet. The optical wire is showing light at its tip so it is still good. Ive tried cycling through the 3 different outputs of the box which are hdmi, dolby, and other. When set up using the original wiring i made sure to change to external speakers.
