Hey @peregrinetx,
Thank you for the quick answer @Streamer317.
You will need to perform a factory reset on the Roku Streambar first. Here is an article that will show you how to factory reset your wireless audio.

After factory resetting, apply your Roku account info to be linked to your original account.
If you have any more questions, feel free to reach out!
All the best,
Alfredo
