Hi everyone, I bought a Samsung 65" UN65JU650D Smart TV with a Samsung HW-JM45C sound bar and bluetooth sub. The sound bar is connect with the audio optical cable when I turn the TV on, change the channel, and with every YouTube video I play. The video starts out with no sound and a clicking noise coming from the sound bar. After 5-20 seconds the sound starts playing. What could be the possible causes of this?
