Why is no sound coming from my Vizio soundbar?

No sound is coming from your Vizio soundbar because your device is OFF or connected to an incorrect cable port. It won’t also produce sound if you’ve set the wrong TV audio output and input source on your soundbar. Having a faulty cable, low volume, muted TV, and outdated firmware can also be why.

Vizio soundbar no sound: 13 quick ways to fix it

---

#1: Check if the soundbar is powered ON

Before you do anything else, check first whether your soundbar is ON.

This is a very basic troubleshooting method. But you won’t believe how many users often overlook this.

Someone might have turned it OFF after use. 

Or perhaps your soundbar’s Eco Mode is ON. If it is, your device will automatically shut off after several minutes of inactivity.

That being said, if your Vizio soundbar isn’t outputting any sound…

Press and hold the POWER button on the device for a few seconds. Or until the LED lights at the center or left side of the soundbar blink.

“My soundbar doesn’t turn ON even after pressing the POWER button.”

If that’s the case, check the power connection of your device.

See if the power cord is plugged properly into the soundbar and the power socket.

#2: Change the TV’s audio output

Regardless of your smart TV brand…

You’ll have to change its audio output every time you connect to a different device.

Suppose it’s your time setting up your soundbar to your TV. Or if you’ve previously disconnected it to connect other devices…

Change the TV’s audio output. Here’s how to do it:

Note: The actual steps may vary depending on your TV brand and model. So, refer to your product manual as well for accurate instructions.

1. Grab the TV remote
2. Press “Menu.”
3. Go to settings.
4. Proceed to “Audio.”
5. Select “Audio Output.”
6. Then, choose your correct connection type.
   (HDMI ARC, HDMI, digital optical, RCA, or coaxial).

#3: Select the correct input source on the soundbar

Next, you’ll also have to select the input source on your Vizio soundbar.

Make sure that it’s the same as your TV’s audio output.

Here’s how to do it:

1. Turn ON the TV and soundbar.
2. Ensure that the devices are connected.
3. Play anything on the TV.
4. Press and hold the INPUT button on the soundbar until the LED lights flash.
5. Then, wait for the soundbar to detect the connection with your TV.

Note: Alternatively, you can press the INPUT button on the soundbar remote. Doing this also enters your device into “Auto Input Search.”

The process is complete once the soundbar starts outputting sound from the TV.

If not, then try the other troubleshooting methods below.

#4: Check if the cable is connected to the correct ports

“I’ve selected the correct audio output and input source already. But my soundbar still has no sound…”

Then, check whether the connection cable is plugged into the correct ports.

Suppose you’ve selected HDMI ARC as your audio output. Make sure that the cable is connected to an HDMI 1 (ARC) port on your soundbar.

Also, connect the other end of the cable into an “Audio Out” port. 

The reason:

Smart TVs have several ports, and many of them are for “input.”

In simple terms, you use input ports to “put” something on your TV. And if you’re using a soundbar, you’d want to “get” something from it.

And you can achieve that by connecting your soundbar to your TV’s audio-out port. 

Note: On some TVs, it’s labeled as “HDMI ARC (Audio Out)” or similar.

#5: Try switching inputs 

Okay, I guess that the solutions above didn’t help at all.

But, don’t worry. You can still try switching inputs to resolve connectivity glitches on your soundbar.

Note: This particular troubleshooting method is only a temporary fix. You may have to redo this process every time the problem gets back. 

Try cycling the connection cable to the other available ports on your Vizio soundbar. Then, reconnect it back to its original port.

Doing this somehow helps refresh the connectivity between your devices. And also the connection between your cable and the port.

#6: Use a different connection cable

A faulty cable can also cause your Vizio soundbar not to work.

So, make sure to check your cable for any signs of damage.

Here are some obvious indications of it:

• Bents.
• Bite marks. 
• Exposed wires.
• Distorted or burnt plugs.

“But my cable is in good condition…”

Then, try testing other cables on your soundbar. That way, you’ll know whether the problem is with the connection cable or the port.

Follow these instructions:

1. Remove the original cable from the TV and soundbar.
2. Connect the test cable to the devices.
3. Change the audio output on the TV.
4. Run an auto input search on the soundbar.
5. Then, play anything on the TV.

If your Vizio soundbar works, then your original cable is definitely faulty. And you have to replace it immediately.

But if the problem persists, check the other solutions below.

#7: Increase the TV and sound bar’s volume level

Another quick and easy fix you can try is to increase the volume level of your TV and soundbar.

Your Vizio soundbar will fail to output any audio if your TV has an off or low volume.

To increase the volume level of your TV:

1. Grab the TV remote.
2. Then, press the VOLUME UP button until you reach your desired level.

And to increase the volume level of your Vizio soundbar:

1. Grab the soundbar remote.
2. Then, press the VOLUME UP button until you reach your desired level.

Or…

1. Press and hold the VOLUME UP button on the device.

Pro tip: Enable CEC on your TV. So that you can control your TV and soundbar using just one remote. Saving you time and effort to troubleshoot your devices.

However, this only works with devices that are connected to your TV via HDMI.

Here’s how to do it:

Note: The process may vary depending on your smart TV brand and model.

1. On your TV remote, press MENU.
2. Go to settings.
3. Select “System.”
4. Click “CEC.”
5. Then, choose “Enable” or “ON.”

#8: See if the TV audio is on mute

Or perhaps your smart TV is on mute. That’s why your Vizio soundbar can’t output audio from it.

You’ll know that your TV is on mute if…

The volume level bar on the TV doesn’t appear when you press the volume up and down buttons. Or if there’s a mute icon at the top-right corner of the screen.

To unmute your smart TV:

1. Grab your TV remote.
2. Locate the mute button.
3. Then, press it once.

Note: Depending on your remote, the mute button has a “MUTE” label on it. Or a speaker slash icon.

After that, you should see a speaker icon on your TV screen.

If your TV has a voice assistant, you can also unmute your TV using it.

Suppose it supports Alexa, for example. Just say, “Alexa, unmute TV.”

#9: Turn off the TV’s internal speakers

To avoid the audio from switching between the soundbar and smart TV…

Turn off your TV’s internal speakers.

That way, the audio from the source would only come out from the soundbar’s speakers. And you won’t have a problem with your Vizio soundbar not producing any sound.

Note: Some smart TVs don’t have the option to turn off the internal speakers. So, if this is your case, proceed to the next troubleshooting method.

The process varies on different TVs. But here’s the usual way to do it:

1. Grab the TV remote.
2. Press MENU.
3. Go to settings.
4. Proceed to “Audio.”
5. Select “Speakers.”
6. Then, toggle it off.

If you want to use your TV without the soundbar, do the same process to activate its internal speakers.

#10: Power cycle the TV and soundbar

If that didn’t work, power cycle your Vizio soundbar and smart TV.

A power cycle helps resolve connectivity issues by restarting the device’s system. So, if your devices can’t seem to work together, do this troubleshooting method.

Make sure to power cycle your soundbar first. Here’s how to do it:

1. Ensure that the device is ON.
2. Remove the connection cable from the TV.
3. Unplug its power cord from the socket.
4. Wait for about 30 seconds.
5. Press the POWER button on the device for about 5 seconds.
6. Replug the power cord into the socket.
7. Press the POWER button to turn ON the device.
8. Then, reconnect it to your TV.

If your Vizio soundbar works after this, then you can stop here.

But if not, power cycle your TV by following these steps:

1. Ensure that the TV is ON.
2. Remove all the connected cables on the TV.
3. Unplug its power cord from the socket.
4. Wait for about 30 seconds.
5. Replug the TV.
6. Press the POWER button to turn it ON.
7. Then, reconnect your soundbar to it.

Still didn’t work? Try redoing the power cycle process longer. Unplug the devices for 10 to 30 minutes.

#11: Update the soundbar’s firmware

Sometimes, having outdated soundbar firmware can also affect some of its functions. And it’s possible that your Vizio soundbar has no sound for that exact reason.

So, to fix the issue with your device, update its firmware.

Here’s how to do it:

1. Visit Vizio’s download page.
2. Enter your soundbar’s serial number on the search bar.
3. Download the update file on the right side of the page.
4. Save it in a USB flash drive.
5. Ensure that the soundbar is ON.
6. Remove the power cord from it.
7. Plug the USB into the USB port.
8. Replug the power cord to the soundbar.
9. Wait for the update to finish.
10. Then, remove the USB once done.

Note: The update process is complete once the LED lights have stopped blinking.

#12: Update the TV’s software

In case the problem is with your TV, you can update its software to resolve any potential issues.

Note: Every smart TV has different ways to update its software. So, refer to your product manual for accurate instructions.

But to give you an idea, here’s how the usual way to update the TV:

1. Get your TV remote.
2. Press MENU. 
3. Go to settings.
4. Select “Support.”
5. Click “Software Update.”
6. Then, tap “Update Now.”

You may also update your TV via USB. Just follow the instructions provided by your product manufacturer.

“There’s no ‘Update Now’ button on my TV.”

Well, that means that your smart TV software is up-to-date.

So, you can skip this step. And try the remaining solution below.

#13: Factory reset the soundbar

As your last resort, factory reset your Vizio soundbar.

Warning: This deletes all data and customization on your device. So, only do this if you’ve tried all the possible fixes above.

A factory reset deletes everything in your device. And that includes the software bugs and electronic glitches. Which may be causing errors with your soundbar.

To do that:

1. Locate the BLUETOOTH and VOLUME DOWN buttons on the device.
2. Press and hold them for about 5 seconds.
3. Wait for the LED lights to flash three times.

Once done, you can retry connecting your soundbar to your TV. And see if the problem has been resolved.

If not, contact Vizio support for assistance.
