S/PDIF is a protocol. Both optical (TOSLINK) & Coaxial (RCA) are using S/PDIF format but optical is more common in sound card.

Please check your HT, iinm it only has optical in.

From your picture above, bottom right connector (white color) should be mini TOSLINK connector. Please confirm by checking with your sound card software. Something like this


If it's so, then you just need TOSLINK to mini TOSLINK cable, or normal TOSLINK cable with adaptor. One forumer sell it in Garage Sales, you can find it here
