How connect TV output to JC2bp

I just got a new smart TV (Sony OLED 77 model XBR77A9G) and want to run the audio through my two channel system (Parasound JC2bp and JC5 amp) for aps run on the smart TV like netflix and amazon. It will be easy to run RCAs from my cable box to the JC2 for cable.... but for audio coming OUT of the TV from streaming services the only output on the TV is a digital audio optical output. My JC2 only has RCA and XLR inputs. 
Any idea how I can connect it? I really want to not have to use the tv speakers or invest in a multi channel system.
