Why Is My Vizio TV Stuck on Low Volume?

Volume problems are common in different smart TVs and are nothing to worry about most of the time. If you can’t see any serious hardware issues or damages to your Vizio TV, it’ll just take a quick fix to get it out of the way.

Sometimes, the most trivial things are what’s causing what seems to be a low-volume issue on your TV. Right off the bat, be sure your TV isn’t muted or that your remote control has enough battery juice to function.

Once you get those out of the way, we can dig deeper into other causes that’ll need more troubleshooting. Starting with:

Faulty Cable Wire Connections

Cable wires play a vital role in ensuring every device’s capacity to function smoothly. You can expect your TV to glitch out in different aspects if they aren’t connected properly.

The same goes if any of the cables you’re using are faulty, damaged, or dirty. All of these can interfere with the device’s signal transfer from one port to another.

Conflict Between the TV’s Audio Setting and Device or Program

Sometimes, the Vizio TV’s advanced audio settings don’t sit well with a specific device or program. This could cause your TV to have a low or, at times, fluctuating volume.

If you’re using external devices to watch on your TV, it’s best to check those first. Otherwise, you’re better off disabling the advanced audio settings on the Vizio TV.

Hardware Issues

If you’ve checked all other ends and it seems like there are no other causes, it could be due to some hardware issues. 

These issues are trickier to deal with since we have to check the TV inside out, and can only be done by a professional.

In this case, try not to tinker any further with your TV to prevent voiding your warranty. Instead, keep your warranty intact in case a replacement is needed and reach out to Vizio support.

How Do I Fix Vizio TV Low Volume?

Volume issues with the Vizio TV are easy to deal with compared to other TV-related problems. All it takes is a few checkups on your wires, external devices, and TV settings most of the time.

Here are some of the troubleshooting steps you can follow to fix your Vizio TV’s low-volume issue:

Secure Your Cable Wires

Whether it’s your TV’s HDMI or other cable wires from external devices, you have to check if it’s plugged in properly. Try to see if there are any noticeable damages or dirt buildup on the cables as well.

The best way to go about this is to:

  1. Unplug the cable wires.
  2. Take a quick scan for any damages or dirt.
  3. Gently brush off any dirt using a small brush or damp cloth.
  4. Follow step 3 for your Vizio TV’s ports as well.
  5. Tightly plug the cable wires back in.

Try Switching Inputs to a Different Device

It’s a good idea to switch inputs to a different device so you can isolate the issue. To switch inputs or try a different device or port:

  1. Head to Settings.
  2. Select Devices.
  3. Choose a different input source from the one you’re currently using.

If you’re using a cable or satellite box, try watching directly from the TV or an app like YouTube. If it sounds fine, you might want to check on the external device you’re using.

Check Your Cable or Satellite Box’s Volume

If the TV’s volume is set high but doesn’t sound like it, check your external device’s volume. Try to increase the device’s volume and make sure it isn’t muted.

If the issue’s with your external device, you might want to reach out to its manufacturer.

Turn Off SRS TruVolume and TruSurround

Another common cause of the low-volume issue involves the TV’s advanced settings. Disabling the TruVolume and TruSurround functions can help remedy the sound glitch.

To do this:

  1. Head to the TV’s Main Menu.
  2. Select Audio Settings > then Advanced Audio.
  3. Toggle the TruVolume and TruSurround features off.


Volume issues with the Vizio TV are not rare and are nothing to be intimidated about. It’s as simple as securing your wires, playing with a few audio settings, and checking your devices.

It’s also ideal to have your TV and other devices neatly set up to avoid damage and tangled wires. This will lessen your burdens on dealing with these common tech issues.
