Hi, @CW_93.
Welcome, thanks for posting here in the Roku Community!
We truly appreciate you inquiring about this, and we'd be more than happy to suggest any workarounds that might help you with your concern.
Firstly, it is important to know that most Roku TVs only support wireless connections with Roku audio products. However, if your soundbar is a non-Roku soundbar, it would be best if you connected it via HDMI cable through the eARC/ARC port at the back of your Roku TV to the HDMI port on your soundbar.
Please let us know if that works for you.
All the best,
Emman
