How do I turn on HDMI ARC on Vizio?

  1. There is usually a button on the soundbar itself to enable or disable HDMI ARC. Check your Vizio soundbar’s manual for the specific location of this button. If you can’t find it, or if your soundbar doesn’t have a manual, you can try pressing the power button and volume up simultaneously. This will often bring up a hidden menu where you can enable/disable HDMI ARC.
  2. If all else fails, there may be a reset button located somewhere on the soundbar. Again, consult your Vizio soundbar’s manual to locate this button, then press and hold it for a few seconds until the LED light turns off. This will reset your soundbar to its factory settings.

What Should I Do If My Soundbar Isn’t Working?

Here are the solutions to solve the HDMI ARC issue on your Vizio Soundbar.

Disconnect other HDMI Devices

HDMI ARC is the best way to connect your Vizio Soundbar to your TV. But, when there are multiple devices connected to your TV via HDMI ARC, the HDMI CEC issue pops up when one device interferes with the functioning of the other.

So, if you have other devices apart from the Vizio Soundbar connected to your TV via the HDMI ARC, disconnect them from your TV and check again.

 This is often a simple but effective solution and you will start hearing sound from your Vizio soundbar via the HDMI ARC connection in no time.

Right HDMI ARC Port

There are multiple HDMI ports provided on some of the Vizio soundbars and not all of them support ARC connection. It is quite possible that you have plugged in the HDMI cable to the wrong HDMI port which lacks ARC functionality.

The same goes for your TV too as it can have multiple HDMI ports and only one of them is for HDMI ARC connection. So, you should check the port on both ends and make sure that you have connected to the correct ports.

If the connection is correct, the HDMI cable might be faulty and you should check with another HDMI cable as well to resolve the issue.

Enable CEC

HDMI CEC (Consumer Electronics Control) is a modern HDMI feature that allows your TV to work better with other peripheral devices. While this feature can be useful, it is often disabled by default.

While it is not compulsory to enable HDMI CEC to get sound output from your Vizio soundbar, sometimes it does create an issue. There is no harm in enabling it and checking the output from your soundbar.

So, you can go to the settings menu on your TV and enable the HDMI CEC if it is toggled off by default. You can consult the instruction manual that came with the TV for better assistance.

Updating the Firmware

If you have not updated the software or the firmware on your TV or Vizio Soundbar for a long time, the outdated software might cause the issue of HDMI ARC not working properly. You should make sure that the devices are updated with the latest software version.

These devices update themselves if they have WiFi connectivity but if there is no WiFi connectivity available to them, they will fail to update from time to time. You can download the latest stable firmware version from the official web page of your TV and the Vizio soundbar, load it on a flash drive, and plug it into the devices. They will scan the flash drive and upgrade the firmware automatically.

  4. In some Vizio soundbar models, you will need to press the volume up or input button with the Bluetooth button. You can refer to the instruction manual for better help.

In order to reset your TV, refer to the official website of the TV manufacturer or the manual that came with the TV in the box.
