A warm welcome here in the Roku Community, @PaulinOregon.
We appreciate you for reaching out and raising your concern here with us. Rest assured that we will assist you in the best way we can.
Please be aware that your Element Roku TV doesn't have a Bluetooth feature, so you can't connect your iLive sound bar to it. However, as you mentioned, you can connect it using an optical cable.
Please don't hesitate to let us know if there's anything else we can be of assistance with and we'd be more than happy to continue doing so. Hope this helps!
Best regards,
Carly
