H, @HRoberts.
It's great to have you here in the Roku Community!
We're glad you shared this with us and we'd like to be able to clarify things for you.
Please note that if you are using a Roku Streambar, you cannot pair any Roku speakers with it, as it only supports a 2.1 surround sound setup. Therefore, you can only pair a Roku subwoofer, instead.
Please see the image below:
For more information about this, you may visit this support article: How to set up a Roku surround sound system.
Let us know if this helps or if you need additional tips to speed things up!
Thanks,
Emman
