Ok im trying to set up the ps3 to amp, thi input on the amp is coaxial and the output from the ps3 is optical but im getting no sound, i have all the inputs set up correctly and have set the ps3 to optical out, problem with the adapter? its plug in, has power, i have an optical going from the ps3 to the "out" in the convertor box, and on the in on the convertor box i have the coaxial from there it then runs to my amp, is that right? should it be the other way about? Thanks for your help. happy new year. Gordie.
