Facing TV Problems? Ask a TV Technician.
Hello and thank you for your question, I look forward to assisting you today. Can you tell me please how you have your sound bar connected to your TV?
Depending on the make and model of both the TV and sound bar, in order to have control and proper audio sync, it needs to be connected to an HDMI port capable of ARC support. Check your TV to see if you have a port marked as such and try that.
I can try to make it a little clearer if I confused you?
