The Vizio brand popped up in 2002 and quickly became a major player in the domestic TV market. Even though Vizio’s TVs are made under license in China, the company itself is based in Irvine, California, and employs both American and foreign workers. The fact that they deliver solid TVs at a very reasonable price is one reason they became a popular brand.
There may be issues with your Vizio TV, and some people have reported not being able to hear sound from it. Without seeing your physical setup and knowing how everything is configured, troubleshooting TV audio remotely can be difficult. You can, however, perform a few basic checks to see if that gets you on the road to hearing and seeing your Vizio TV again.

The Solutions – No Sound Coming from Vizio TV
In order to determine where the sound issue is coming from, you can perform some basic checks.
Check the TV. Remove the TV from the wall outlet and leave it for about 30 seconds. Reconnect the device and retest. In this way, the TV can be fully powered down and reset. It should now be resolved if the problem was a temporary voltage or power issue.
Check the cables. It is usually the second thing to test. Is there any evidence that any of the cables have been moved or knocked? Be sure all cables are seated fully and swap them out if you have spares. HDMI cables, particularly manufacturer-provided cables, are notorious for being flaky, so you should definitely swap for a spare.
Check the feed. What is the source of the TV’s signal? Does it have a cable box? Is it satellite? Do you stream? Try changing the feed and see if the problem persists. You can stream something over WiFi or cast something to the TV from your laptop or mobile device if you have a cable box connected. When you change the feed, if audio works, it’s the feed and not the TV. There may be a fault or a setting problem with your Vizio TV if there is still no sound.
Check external audio. If you use a soundbar or surround sound, remove it and test with the default speakers. If you hear sound, it’s the external hardware. It’s the TV if you don’t.
Check other devices. Try connecting your gaming console, Amazon Firestick, Roku device, or any other tech you have to your TV. In the case where the sound works on your Xbox but not on your cable box, either the cable box’s settings (for example) or the HDMI port are to blame. If you suspect the latter, plug your cable box into the Xbox’s port and see if the sound works. In that case, your TV has a bad port. You might have a cable box issue if it doesn’t (again, for example).
Check audio settings. On the TV menu, access the audio settings and check them. If you select Reset in the audio section, they will be returned to the defaults. Retest after confirming the change. It shouldn’t really make a difference, but it’s worth a shot.
Perform a Factory Reset. You can try a factory reset of your TV based on what the troubleshooting steps above have revealed. This reset won’t fix hardware problems, but it will fix software and settings problems. Use your remote to navigate to the Menu on your TV and click on “Reset & Admin.” Once there, click on “Reset to Factory Defaults” and follow the instructions.
Troubleshooting TV audio
Any technical issue should be troubleshooted by simplifying the setup as much as possible. When there is no sound coming from a Vizio TV, you should remove all external audio and input devices except one. Typically, I connect a DVD player to the TV using HDMI and then SCART. On the TV, I play a DVD I know works.
When there is audio, I know the problem is not with the TV. When there is no audio, I swap HDMI for SCART and retest. In this case, I know that the issue is with the TV itself. As a result, I won’t have to spend hours trying to find a problem with a surround sound setup that doesn’t exist.
In this case, you may want to check the audio settings or contact Vizio customer service. Make a warranty call and get your TV fixed if it is still under warranty. When your TV is out of warranty, you must decide what to do.
Early Vizio TVs had an audio board issue. As part of the mainboard, it had inherent weaknesses. In order to repair the fault, five components need to be changed, which could be quite expensive. To get expert advice, you may need to speak with a professional.
LCD and LED TVs are cheaper than ever, but they are usually cheaper to buy than to repair. Your TV may need to be repaired or you may need to replace it with a newer model. In this case, only a professional TV repair guy can offer you proper advice.
Additional Frequently Asked Questions
Vizio TVs allow you to turn off your speakers. Select the audio settings from the menu on your television. Toggle on the TV Speakers option.
Vizio’s warranty support can be reached by calling 855-209-4106 or visiting their website.
Audio outages that come and go are more likely caused by a bad connection. It would be helpful if you could try another HDMI port or cable if you are using the HDMI ports. Connect an external speaker or soundbar if you have one. In this case, the problem is not the connection, but a setting within the TV’s menu or faulty hardware.
