I have a TCL RokuTV with the StreamBar Pro and Roku Wireless Speakers. I am very frustrated that the only configuration allowed is to use the StreamBar as the sole front audio device and the Wireless speakers MUST be used as REAR satellites.
The stereo separation on the streambar is really narrow, and there are plenty of setups that use front left/right speakers with a soundbar for the center channel. This is a common setup and it would be really easy for Roku to implement in the software.
