Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; to which you want set-up codes; in the "Search box at the top right of the display window" to get gathered related posts.

If the TV and sound bar have an optical connector, then get the optical cable to connect the two. If not then use the audio out jacks on the TV and don't forget to change the audio set up to switch the sound to the sound bar.

After only three days I would take it back, or at least take the remote back and try it on a different sound bar.

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.

Unplug the sound bar for about 10 seconds.

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!!
