I had an all in one Sony surround sound system that I got free with my Sony HD TV. However it had no digital inputs and I wanted to connect the PS3. All the surround speakers connected to the Onkyo but I obviously needed a new subwoofer.
The problem I have is that I have now tried 3 different powered subwoofers and can get no sound from any of them. The latest is the Wharfedale WDHX-160SSP.
I have tried connecting with both a coaxial digital audio cable and also with a basic phono cable. Neither work. I have tried various calibration settings from -3db to +3db and at various volume settings on the subwoofer from about a quarter all the way to full. It goes without saying that I have tried all the various combinations of the above. I have set the system to 5.1 (correctly) and (in config) I have set the subwoofer to 'Yes'. Audyssey recognises all of the other speakers. I am connecting via the subwoofer pre out on the Onkyo but have also tried the other subwoofer connection, to no avail.
Please help, I have the distinct feeling I am probably missing something very obvious.
In advance: Thank you
