Just bought a G-Sonic 32 inch sound bar came home hooks it up to my Vizio 42 inch tv no sound with bar??? RCA on TV and bar a PC and plug in no sound ?


I had the same problem, no sound from tv to the sound bar. I hooked up the output for sound from the sound source, your cable tv box or satellite receiver and ran it to the sound bar, and then received sound.

42 inch vizio has picture (direct tv) but no sound. Tv is not on mute.


Did you check the RCA AV Cables? The ones with the red, white yellow?

What is the connection you have from Direct TV box to your TV. You might want to start on that.

It might probably as well related to any of the remote controls settings. Either of the Direct TV control or TV Control.

1. Check the cables
2. Check if there is any function on the Direct TV remote that will turn off the sound
3. CHeck the Vizio TV Menu Settings.
4. Try with other component such as DVD to discard the possibility of malfunctioning VIZIO Speakers.

Vizio offer a good customer service if still under warranty.

God Bless You!!

Vizio Speaker Making a Buzzing Noise


My 32" vizio I bought a week ago does the same things.

Buy an external sound system for the tv. Turn the speakers off in the TV menu. Hook the sound system up to the out speaker hookups on the tv.

You will not only have better found, you will fix the speaker buzz problem.
