I believe there is a bug in the way the Android 14 build on the stream tv sound bar handles multiple game controllers. I tried to submit a ticket on the soundbar itself, but it kept reporting errors.
The problem is when I connect two bluetooth game controllers of the same type. If I connect two switch pro controllers, they behave as one controller. The OS reports that both are paired, but gaming apps (e.g., steam link, moonlight, etc.) recognize the two controllers as a single controller. This doesn't happen if I connect a switch pro and an xbox controller, only when connecting two of the same type of controller.
I have several stream tv devices throughout my house and the soundbar is the only device that has this problem.
In the pictures, you can see that three controllers are connected (Pro Controller x 2, Xbox controller x 1) but the OS recognizes the two pro controllers as a single controller.
