#2: Change the sound bar’s input source
You may also try changing the input source of your Vizio soundbar.

- Devices are incompatible.
- Cable connection is faulty.

Your subwoofer can sometimes get disconnected from your Vizio soundbar.
When that happens, you can just simply relink your subwoofer with your soundbar.
Here’s how to do it:
Note: Some steps may vary depending on your devices’ model.
Step 1: Plug and turn on your devices.
Step 2: Bring the subwoofer closer to the sound bar. Move it about 1 ft (30 cm).
Step 3: Press and hold the “Pairing” button on the subwoofer for about 5 seconds. Or until the LED lights blink.
Step 4: Press and hold the “Power” button on the sound bar for about 10 seconds. Or until the LED lights blink three times. This indicates that your devices are now paired.

#4: Move the subwoofer closer to the sound bar
If your subwoofer is too far away from your Vizio sound bar…
It may fail to receive audio signals from it. And so cause the audio from the subwoofer to cut off every few seconds.
So, consider moving your subwoofer closer to the sound bar. And ensure that there’s a direct line of sight between your devices.
Ideally, your subwoofer should be within a 10 ft (3 m) range from your Vizio sound bar.
#5: Turn off the sound bar’s “Eco mode”
After several minutes of inactivity, your Vizio sound bar will turn into Eco mode. Which turns off your device.
Note: This is also known as the “Energy Star.”

So, to resolve the problem, disable the Eco mode on your Vizio sound bar.
To do that:
Step 1: Locate the POWER and VOLUME DOWN buttons on the sound bar.
Step 2: Press and hold the buttons for about 5 seconds. Or until the first 4 and last 4 LED lights glow.

#7: Update the sound bar’s firmware
Having outdated sound bar firmware can also cause your subwoofer to cut off audio.
So, make sure to keep your device up-to-date.
You can update its software either:
- By navigating the sound bar’s settings.
- By auto-updating it through the Vizio SmartCast app.
- By plugging in a USB that contains the software update file.
Pro tip: If your sound bar is SmartCast-compatible, connect it to the Vizio SmartCast app.
That way, you won’t have to manually update your device every time there’s a new software version.
#8: Leave enough clearances around the sound bar
When your sound bar is overheating, some of its functions may fail to work. And that includes its connectivity to your subwoofer.
That being said, make sure to protect your device from overheating.
One way you can do that is by leaving adequate clearances around your Vizio sound bar.
Make sure to leave at least 4 in (10 cm) gaps for ventilation.That way, you can keep your sound bar cool even when in use.
#9: Turn off the sound bar for a while
Do you use your Vizio sound bar frequently? Do you keep it powered ON most of the time?
If yes, consider turning it off once in a while.
When you keep your device turned ON all the time, its components will continue to run. Which can also cause your sound bar to overheat.
Turning it off once in a while allows your sound bar’s components to rest and cool. Plus, it helps keep your device in its tip-top condition.
#10: Remove other WiFi/Bluetooth-enabled devices nearby
WiFi and Bluetooth interference can also cause your Vizio sound bar subwoofer to cut off.
This happens when a nearby device interrupts the signal from the sound bar to the subwoofer.
To prevent connection interference…
Make sure to remove electromagnetic devices near your sound bar and subwoofer.
And this can be a:
- WiFi router.
- Baby monitor.
- Wireless phone.
- Microwave oven.
- And other wireless devices.
#11: Factory reset the sound bar
If all things fail, factory reset your Vizio sound bar.
Warning: A factory reset deletes data and custom settings. So, only do this as your last resort.
Doing this also removes electronic glitches and software bugs that cause connectivity errors.
Plus, it turns your device settings back to default. Which is a good thing in case you’ve messed up something on its system.
Here’s how to factory reset a Vizio sound bar:
Note: The instructions may vary depending on your device model. So, make sure to check your product manual as well.
Step 1: Find the BLUETOOTH and VOLUME DOWN buttons on the sound bar.
Step 2: Press and hold the buttons for about 5 seconds. Or until all the LED lights blink three times. This indicates that the device has been reset back to its factory default.
If the problem persists, contact Vizio support for repair or replacement.
