Connecting a Vizio Soundbar to a Television

You can connect a TV using this digital connection if your Vizio soundbar offers an optical digital audio output: 

To do so, follow these steps:

Step 1: Both the soundbar and the television should be turned off.

Step 2: Connect one end of the optical (S/PDIF) cable to the soundbar's optical jack.

Step 3: Turn on the soundbar and the television.

Step 4: You can select the optical input by tapping INPUT on the top of your soundbar or OPTICAL on the remote control.

Another Alternative is to Use an Analog Connection to Link the Soundbar to a Television:

For an analog connection, follow these steps:

Step 1: Both the soundbar and the television should be turned off.

Step 2: Connect the white and red connectors on one end of the audio cable to the analog audio output on your TV.

Step 3: Turn on your soundbar and television.

Step 4: You can select the associated input by pressing INPUT on the top of your soundbar or IN on the remote control.

How to Control a Vizio Soundbar with a Vizio TV Universal Remote

You can configure a device button (AUX or AUDIO) to control your soundbar if you have a Vizio TV with a universal remote. Use code 31517 if your remote has a 5-digit programming code. Use 1517 if your remote has a four-digit code.

To use the universal remote to control the soundbar volume rather than the TV volume, follow these steps:

Step 1: Using the remote, press and hold the SETUP button until the light flashes twice.

Step 2: Count to nine, then three. There are two flashes of light.

Step 3: Press and hold the device button (DVD, TV, CABLE, etc.). There are two flashes of light. While using the device you chose, the volume buttons on the universal remote now control the soundbar.

Resetting a Vizio Soundbar

To return a Vizio soundbar to its factory default settings, follow these steps:

Step 1: For 5 seconds, press and hold the Bluetooth and Volume Down (-) buttons together. This will clear off all of your choices and settings.

Step 2: To reset your soundbar to factory default mode, press and hold power, volume up, and volume down for 10 seconds on select models (including the Vizio 5.1 soundbar).

Lights on the Vizio Soundbar are flashing up and down.

The number of light blue bars grows as the volume on the soundbar is increases. The number of lighted blue bars reduces when the volume on the soundbar is reduced, and the blue bars flash when the volume is muted.

Troubleshooting for the Vizio Sound Bar Remote

Dead batteries, not directing the remote correctly to the soundbar, or the button not being supported could all cause problems with the remote.

To see if your remote works, try the following:

Step 1: Replace the batteries in the remote control.

Step 2: Point the remote at the center of your soundbar when pressing a button.

Step 3: Some of the buttons on your remote may not be supported by the streaming program if you're using Bluetooth. Pandora, for example, does not support the Black button.

Crackling Noise Vizio Soundbar

A connectivity issue could be indicated by crackling noises from your Vizio soundbar. Check for loose wiring connections and make sure they are securely linked. If the audio cable is damaged, try using an alternative audio cable.

Interference from surrounding electronic gadgets is another probable cause. Turn off any electronic devices in the vicinity that could be interfering with the speaker's sound.

You can also try the troubleshooting procedures below:

Step 1: If the last volume setting was too loud, turn it down.

Step 2: Change the wall AC socket where the power cord is plugged in.

Step 3: Change the audio input on the Vizio soundbar. The problem is most likely with the speaker's previous input if the audio is fine while the cables are attached.
