Greetings from the Roku Community, @Fafahead!
Thanks for your inquiry regarding the compatibility of your Roku Subwoofer. We're here to assist.
Please note that your Roku subwoofer is specifically engineered to pair seamlessly with Roku audio host devices, including the Roku Streambar® SE, Roku Streambar, Roku Streambar Pro, Roku Smart Soundbar, and Roku TV™ systems. Currently, it is not compatible with other television models or pre-existing sound systems, meaning direct connections to those devices will not work. For optimal audio performance, ensure it is only connected to the listed Roku products.
For more information, we highly recommend visiting this support article: Getting to know your Roku subwoofer.
We hope this information helps.
All the best,
Emman
