Greetings @RockingRonnie
Welcome to the Roku Community and thanks for posting regarding connecting your Roku Streambar to your home setup.
Is there a reason why you are trying to connect the Roku Streambar to your AVR? The Roku Streambar should be connected to the TV through both HDMI (non-ARC) and optical cable.
For more information about how to connect your Roku Streambar to your TV through HDMI (non-ARC), visit our Support page here: Set up your Streambar Pro
Please keep us posted what you find out and we will be more than happy to continue assisting should you need further assistance.
Thanks,
Danny
