Solved! How to connect non Roku speaker to TCL

Solution
That TV doesn't seem to have bluetooth so it might not even work with the Roku speaker.
You can connect the TV headphone out to speaker aux input. No delays to deal with.
Start with the TV volume about 1/4 up so you don't overload the input of the speaker. if the TV volume is too high you will hear constant distortion regardless of the the volume setting on the speaker itself.
