Hi and thanks for the reply.the micro USB from the sound bar is most probably only for charging and not for audio data.
But which sound bar model is it exactly?
Maybe a blue-tooth transmitter can help
That´s not how this USB works. It´s a port for storage devices. The soundbar can play audio , video, foto files from USB.The sound bar USB is for input of photos and videos so must have an Audio input of some sort I assume. The model is HW-R430.
