1 of my 2 Roku wireless speakers has stopped working. Once it's plugged in, it begins thumping rhythmically like a heartbeat. It will do this forever until unplugged. Holding the reset button for 10 seconds or longer does nothing. The rear power LED will never light in any scenario - reset or otherwise. The speaker will not respond to pairing.
I have also tried moving it closer to the TV, plugging it into other outlets, using the other speaker's power cord, unplugging for an extended period of time.
I have submitted an RMA request.
