Connecting Sonos Port to Denon AVR x550bt
Hi I’m really struggling to understand how to setup my new Port to my Denon AVR x550bt Receiver. Im not technical, but there are a number of RCA ports available for AUDIO IN but can't seem to get any volume out of the speakers when I turn it on to Media player or CBL. The surround sound speakers are being used by sky box/HDMI input

Any help would be appreciated?
Cheers
