I would also be interested in an answer to this. I just purchased a TCL Alto 8i Atmos soundbar on the cheap for Cyber Monday and though I am very impressed with the sound you can't beat actual rear channels! Question is can you pair the Roku Wireless Speakers with a TCL Alto Soundbar?
I've been trying for weeks to get them to work together and it will not happen. The Sound bar works when I'm on Netflix, Hulu etc. The speakers work when I'm watching TV. Please advise! I'm ready to Return it All.
This would appear that your Soundbar and Wireless Speakers are not paired together. We would trying to pair your Wireless speakers to your Soundbar to see if that resolves the issue you are experiencing.
The answer is NO. Roku wireless speakers only pair to Roku tv's and Roku soundbar/streambars. that's it. The TCL Alto 9 is Roku ready, but it only pairs to Roku tv's nothing else. Just so the roku remote would control the TCL soundbar.
