I plugged in my sound bar via digital optical audio cable and it makes a horrible sound. Changed setting to digital and plugged into proper inlets.
That can be a bad optical cable or port on either of the devices. Need to do a bit of testing, try another cable, try the soundbar on another device, another speaker setup on your TV.
