I am having the same issue of not being able to connect Roku Wireless Speakers.
I also have aTCL Roku TV, Roku Streambar Pro and Roku Subwoofer, which I bought before the speakers, and they connected perfectly. I bought them in December 2023, and they connected on my first attempt, no problems. They worked for about one week, then stopped working. I called support, they walked me thru a number of things to try, but nothing worked. I've been all over the internet looking for something that would work, but nothing helped.
The worst part of the whole experience is that support told me on the phone they were aware of the problem it was an existing issue and that it would be resolved within 24-48 hours. They would call me to walk me thru how to remedy it, if I wasn't available, they would email the instructions. I got a follow up email, since then no communication at all and no reply to my emails, even though they said I can respond to the email. They have given me no updates on how they are attempting to resolve the problem.
There was a TCL Roku TV update shortly after I first was able to connect the speakers which seems to coincide with the time, they stopped working. I appreciate any help. Here is my info:
TCL Roku TV: model 43S45OR, serial X01300PXMTPM, hardware ID G182X
Roku StreamBar Pro: model 910IR2, serial YL000E3077
Roku Wireless Speakers: model 9020X, serial 026286112545 and 026286224016
