Ryan uses Amazon's Echo Dots and he tries to connect them to his home theater system, but when he tells them to play multi room, the music plays from the Dots only. Leo says the problem could be Bluetooth latency from wirelessly playing from one Dot to another, causing an echo chamber. Leo says using a hardwire option would probably make it work. It could be an intentional design decision that triggers via Bluetooth limitations.
