The nature of whatever is on the upstream side of a digital signal is invisible to the device at the other end of the cable. Bits is bits, as we say. The undefined 'satelite to optical audio' device is probably at fault or not set right. PLUS, on theOnkyo you have to assign digital inputs. Read the manuals.

Use a search engine for "Onkyo TX-SR501 manual"??

You might also hunt for the TV manual as IT is a player in the scenario, too.

What model Bose? If the speaker wires have molded ends they are possibly NOT electrically compatible with anything but the electronics they were sold with.
