Hello Bunderstorm,
Welcome to the Roku Community.
Thank you for reaching out regarding your issue with connecting your LG Soundbar and Subwoofer to your Westinghouse Roku TV via Bluetooth.
Before you can enjoy your favorite streaming content in surround sound, please be advised that the Roku TV does not support Bluetooth connectivity with speakers, you must connect your audio/video receiver (AVR) or soundbar to your Roku TV using an HDMI cable or optical cable.
To learn more, this article provides additional details about How to connect a surround sound system to your Roku TV
Please let us know if there is anything else we can assist you with.

TCL and now Roku sell wireless Soundbars that connect to Roku tv's via WIFI-direct, not Bluetooth.
Like this one:
Roku TV Wireless Soundbar – TV Soundbar for Home Theater | Roku
As it says in the description it says it streams music from Bluetooth device, but doesn't transmit via Bluetooth. Only Wifi.
