How to connect my SA30 to my Arcam AVR11

1

Hi All, Newbie here. I have recently purchased my SA30. I have it connected to my Arcam AVR11 for the front speakers, also my sub, I have no sound coming from the right side speaker? Works fine if I’m only using the SA30, but no sound from sub and right front speaker when listening through my AVR11? Any and all help appreciated. Thanks.
