Possible solutions:

Check the audio connections of external devices that may be connected to the HDTV.
If you are using an antenna, the signal strength of the channel may be low. Make sure your antenna is connected securely to the TV and move the antenna around the room or close to a window.

If the issue persists (or if you require further explanation), you'll have to consult Vizio: use the contact information here--https://www.contacthelp.com/vizio/customer-service.
