I'd like to set up a home theatre with wireless surround sound, to minimize the number of wires. The projector will be overhead, so it makes sense to put a Roku Ultra 4K there with an HDMI to the projector. I would like to have a set of speakers or sound bar in front and speakers behind and probably a subwoofer. I see that Roku has wireless speakers, and it also streams to various audio devices. However, it is not clear if all of these can do wireless surround sound from the Roku 4K ultra to all of the devices without any additional hdmi cables. Can this be made to work, either with Roku audio or a 3rd party audio product?
