Question Vizio soundbar model: sb3251n-e0

[arkanine]

My subwoofer is synced ,light is solid red after pairing, but for some reason I have no sound from my speakers. The main subwoofer has power ,but no sound from the speakers. Any clues? Checked cables they are matched,

What is the soundbar attached to? What means (i.e., HDMI, Bluetooth, etc) is the soundbar attached to the other device?

Is the TV set to external speakers?
