Connecting a Vizio Soundbar to TV with AUX: Step-By-Step Guide

Connecting your Vizio soundbar to the TV with an AUX cable should be a walk in the park, especially if you’ve ever unboxed or connected any electronic before.

Step #1 Unpack your Vizio Soundbar

First, you want to take it out of its original packaging, then mount it on a flat surface. This surface should give you enough allowance to work on the back when the AUX-in port is located, and also be sturdy (preferably a TV shelf/stand) so your device doesn’t fall off.

Step #2 Take out your AUX Cable and Plugin

Now, remove the plastic cover from both ends of your cable, then proceed to plug in one end of your TV. Plug the second end into your soundbar and get ready.

Step #3 Select AUX Input Method

If your device is not yet turned on, you’ll want to right away, connect the power cable right away and get it on first before continuing. Once on, press the input button on your Vizio soundbar remote, and use the directional button to navigate to AUX or AUX Audio. The sound from the TV should start playing through the soundbar automatically.

Step #4 Turn Off TV Speakers

This step is only necessary when you notice an echo in the reception after step #3. To do this, on the soundbar remote, you’ll want to navigate through Menu >> Audio >> TV Speakers Off. This will turn off the TV’s sound to ensure that the delivery is only coming from the soundbar’s speakers. Alternatively, you can use the TV’s remote to lower its volume or put it on mute entirely.

Connecting a Vizion Soundbar to TV with HDMI ARC/Optical Audio/Coaxial Audio/RCA Cable

Your Vizio soundbar model will automatically determine the kind of connector you’ll be using. As these soundbars aren’t restricted to a particular connection method, it’s good to learn different ones based on your specific preference and the kind of audio quality that comes with it.

Overall, you’re going to be following the same steps as outlined for an AUX cable, the only difference is the new cable’s name, which should correspond with your selected input method as you see in step #3.

How to Connect a Vizio Soundbar with Bluetooth

If your Vizio soundbar’s model supports Bluetooth then this is a feature you may want to try especially if you love playing stuff from your smartphone. All you need do is press and hold the Bluetooth button on the side of your soundbar; it’ll put the soundbar in pairing mode. Alternatively, you can use the soundbar’s remote to navigate through Menu >> Settings >> Additional Settings >> Bluetooth Audio, then press OK to turn it on.

Once your soundbar’s Bluetooth is turned on and discoverable, you’ll want to go to your source device, search for it, and have it connected.

Vizio Soundbar Troubleshooting Guides: What Can Go Wrong & How to Fix

  • The Soundbar Fails to Connect to the TV

If your soundbar is failing to connect to the TV for any reason, there are a few troubleshooting measures you could try. First, if you’ve been able to connect it to your TV before, a simple change of cable, power cycling, or factory reset should be enough to have it fixed. However, if you’ve never connected it to a TV before, you’ll want to start connecting source by source, not all at the same time.

  • Soundbar Sound is Noisy or Low Quality

If you’re having a sound issue on your Vizio soundbar, your attention should first be drawn to the audio settings, especially if the audio has been working perfectly before. A quick option is usually to perform a factory reset or to undo whatever special audio settings you’ve made earlier.

While that’s the case, if you use an HDMI, Optical, or AUX connection, you may want to check your cable to see if it’s still working. Also, you could try switching between connections to see if another gives you a better reception.

Lastly, an update of your Vizio soundbar’s firmware is logical if the issue keeps recurring whenever you get to have it solved by a simple hard reset.

  • Soundbar Audio Out of Sync with TV

If your soundbar’s audio and your TV aren’t in sync, it’s most likely as a result of you streaming at a high quality and your HDMI cable isn’t fast enough to carry the information properly. Meanwhile, the most ideal method is to adjust the TV audio/video lip sync settings.

Also, if you’re playing through a TV box or decoder, you’ll want to plug the decoder audio directly into your soundbar using the AUX cable, while the RCA or HDMI ARC cable goes to the RV for video only.
