Causes of Vizio Soundbar No Sound HDMI ARC

The HDMI ARC port on the Vizio soundbar doesn’t have an optical digital audio out, but it does have a digital optical output. From what I’ve learned, one of the most common problems with the Vizio Soundbar HDMI ARC is that it doesn’t work when it’s connected to an HDTV. Here are some of the most common reasons why this happens.

  • Vizio Soundbar wasn’t set up or put in place correctly.
  • Some strange things plug into the TV’s ARC HDMI port.
  • Make it harder for the Soundbar and TV to connect.
  • The Soundbar doesn’t have enough HDMI ports.

Check the Soundbar’s plug and power

If your Vizio sound bar unexpectedly stops working after you set it up, test to see if this is plugged in properly. And that the power cord to the sound bar is in good shape.

In this scenario, let’s assume your sound bar isn’t experiencing any issues with power supply. See if the device is turned on. To do just that, you have to press the sound bar’s POWER button. If the device has a blinking light in the center or even on the left side, it is on. After pressing the POWER button, wait a few seconds for your device to switch on before using it.

Make sure you’re plugging in to the right port

If you’re using the Vizio sound bar for the first time, actually pay attention to the information below. This is something that most first-time users don’t consider. If any of the following applies to your sound bar’s HDMI ARC, it won’t work:

You might have plugged the cable into the port that wasn’t made for HDMI ARC. You can’t use HDMI ARC with your smart TV since it doesn’t support it. Check to determine whether your television has an HDMI ARC connector before connecting your soundbar to it.

When it comes to HDMI ports, HDMI ARC is usually the first. There is a label that reads “HDMI 1 (ARC)” or “1 (ARC). A green line may be seen surrounding the port on occasion. To make it stand out from the crowd.

The other end of the HDMI cable should be plugged into your sound bar’s HDMI ARC connection in the same manner. On the device’s rear, you’ll see a label that looks somewhat like this.

What if your TV doesn’t have an HDMI ARC port? In that case you won’t be able to connect your Vizio sound bar to it over HDMI ARC. If this is the case, you may connect to a compatible smart TV. Alternately, you may choose from a variety of sound outputs.

Use a Different HDMI cable

You could connect the cable to both of the HDMI ARC ports. The sound bar still doesn’t work. If so, your HDMI cable might be damaged. Or that the cable doesn’t fit the connection.

Some clear signs that an HDMI cable is broken are:

  • The wires have been bent.
  • Burned-in plugs
  • There are bite marks all over the place.
  • Plugs that have lost their effectiveness.
  • Wires exposed.

Let’s say you can’t see any damage to your HDMI cable. How to check if it’s broken:

  1. Investing in a second HDMI cable is your best bet.
  2. Use the HDMI ARC ports on your sound bar and TV to connect this device together.
  3. After that, mount your sound bar.

The original HDMI cable may no longer be working if the sound bar is working. That’s why, you’ll need to buy a new one ASAP. If you have an HDMI 2.0 cable, I highly recommend that you use it.

Set TV and sound bar audio to HDMI ARC

After using HDMI ARC to connect your sound bar to your TV, users should start changing the audio inlet and outlet settings. And that goes for both your smart TV and your sound bar. Here are the steps you need to take. The steps may be different depending on the brand of your TV and sound bar.

To change how a smart TV plays sound:

  • Use the remote to press the MENU button.
  • Click on settings.
  • Click on “Audio.”
  • Click “Output Sound.”
  • After that, choose HDMI ARC.

And thus to change where the sound bar gets its sound:

  • Get the remote for the sound bar.
  • Press the button for input. There is a box with an arrow on the input button.
  • After that, choose “HDMI ARC.”

Turn on the TV’s CEC

Consumer Electronics Control, or CEC, is a control setting that most smart TVs have. This means you can control all of your HDMI devices with just one remote.

Even though this doesn’t have a direct effect on your Vizio sound bar’s HDMI ARC connection. If you turn it on, your sound bar will turn on when you turn on your TV. This makes it less likely that your sound bar won’t work. The steps may be a little different depending on the type of TV you have. So, check the manual for your product for detailed instructions.

To make your TV’s CEC work:

  • Use your TV remote to select MENU.
  • Click on settings.
  • Continue on to “System.”
  • Choose “CEC.”
  • Then, click “Enable” or “ON.”

Unplug the HDMI cables

If it doesn’t work, try unplugging and re-plugging every HDMI device on your TV. Sometimes, when HDMI devices are connected, they interfere with each other. If that’s what’s wrong with your HDMI ARC on your sound bar. The best thing to do is to turn off everything.

Here’s the right way to do it:

  • Unplug everything that uses HDMI on your smart TV.
  • Hold on for about a minute.
  • Plug your sound bar’s wire back into the HDMI ARC port.
  • Put your sound bar in place next to your TV.
  • You can then proceed to connect the remaining HDMI devices one at a time.

When you plug your TV back in, the sound bar must be the first thing you plug back in. So, do what the steps say to do.

Turn off Eco mode on the sound bar

You could also try turning off the Eco Mode on the sound bar of your Vizio.

When Eco Mode is on, your sound bar turns off after a certain amount of time. The majority of the time, between 5 and 10 minutes after the last sound was heard. If you haven’t used your sound bar in a while, it might stop making sounds all of a sudden.

To stop the Vizio sound bar’s Eco mode:

  • Press and keep holding the device’s VOLUME DOWN buttons.
  • Then, press and keep holding down the POWER button.
  • Hold on to them for another 5 seconds. Or until you hear two beeps with a low tone.

On a few models, the Eco Mode turns off when the sound bar’s LED lights go out.

Upgrade the sound bar’s firmware

If the problem wasn’t fixed by the fixes above, check to see if your sound bar’s firmware needs to be updated. If it has, make sure to install the update as soon as you can.

Here’s what you need to do:

  • Fist click
  • Type in the serial number of your sound bar.
  • Click “Update Firmware.”
  • The file for updating the firmware is on the right side of the screen.
  • Put it on a USB memory stick.
  • Put the sound bar to work.
  • Pull the power cord out.
  • Connect the USB stick to the sound bar.
  • Plug the power cord back in.
  • Wait until the update is done. The process of updating is done when the LED lights stop shining.

Upgrade the TV’s software

Make sure your TV software is up to date if you’ve previously upgraded your sound bar.If your TV’s software isn’t up-to-date, this might not be able to send and receive connection signals. And that could be why your sound bar’s HDMI ARC doesn’t work.

So, update your TV to fix any problems your smart TV might be having with its connections. The steps depend on the brand and model of your TV.

But here’s how it usually works:

  • Press MENU on the TV remote.
  • Click on settings.
  • Choose “Help.”
  • Click on “Update Software.”
  • Tap “Update Now” after that.
  • Check the box next to “Update automatically” if you want to do this. You don’t have to do it by hand every time.

Unless you see a “Update Now” button on the screen, the TV is current. As a result, the solutions suggested below may help you resolve the issue.

Power cycle the TV and sound bar

Power cycling, or “rebooting,” is a way to restart your device’s operating system. And this helps in the elimination of software faults and defects. That could well be preventing us from connecting.

Important information and settings that you’ve made yourself will remain intact. That means that you don’t need to create a duplicate of your data. Try turning off and turning on your TV and sound bar again if none of the previously mentioned remedies worked. No matter what device you want to restart, the steps are the same.

Here’s what you need to do:

  • Make sure the device is switched on.
  • Pull the device’s plug out of the power outlet.
  • Wait around ten minutes.
  • Plug the device back in.
  • Then, check to see if the problem has been fixed.

If this didn’t work, try leaving it unplugged for another 30 minutes.

Hard reset the sound bar

If nothing else works, you can do a hard reset on your Vizio sound bar. All of your data will be deleted and the device will be restored to factory settings if you do a hard reset instead. So, this is your only choice left.

To correct faults and malfunctions, a complete wipe is necessary since it removes everything. So your sound bar works better because of this. And easily connect with the other smart devices. Depending on the type of device you have, the buttons you just had to press may be different. Also, make sure to read the manual for your product.

Here’s how to reset a Vizio sound bar to factory settings:

  • Press the device’s BLUETOOTH button and the VOLUME DOWN button.
  • For about 5 seconds, press and hold the buttons. Or until three of the 12 LED lights flash.

After you hard reset your sound bar, you’ll have to set it up again with your smart TV.

Connecting to another TV

You may use a different TV to connect the Vizio soundbar if the first one isn’t working properly. Your TV may be faulty if the soundbar works on other TVs. For HDMI ARC to work, either the port is broken or some settings need to be changed. In this situation, you can look in the TV’s manual for help.

Also you can check the soundbar and TV for the latest versions and updates. Other TV brands use older firmware that doesn’t work with ARC compatible connections. To allow ARC only CEC connection, it is best to update your TV’s software to the most recent version. To accomplish this, connect the Vizio TV to the web and then navigate to the settings page. Click on firmware update.

People who had the same problem with their Vizio sound bar HDMI ARC not working fixed it by updating the firmware. Turn both of them on and see if the sound bar can now play sound.
