🌟【About Foxnovo Sound bars】When using the AUX to connect, plug the 3.5MM aux cable into the Soundbar's input port, and the other end plug into the TV's AUX output port. Please do not plug it into the TV's AUX input port, otherwise it will produce noise. If there is no AUX output port, please plug the 3.5MM cable into the RCA adapter and connect it to the RCA output port of the TV or plug it into the AUX output port of your TV box. And if there is any problems about it please contact us!
