Some things to avoid issues with a Vizio subwoofer include making sure the power cord can’t come disconnected easily. Changing the source input and turning off Eco Mode can help resolve sound cutting in and out and an occasional relink to your soundbar is necessary.
To reset the Vizio Soundbar Bluetooth settings, go to ‘Reset Audio’ settings and select ‘Reset All’. Press ‘OK’. The LED display lights will all blink three times to signal the soundbar has been reset. All paired Bluetooth devices will need to be connected to the soundbar again.
When your Visio Soundbar is not working, you need to do a soft reset. This is done by disconnecting the power, either by unplugging it or by turning off the breaker in the breaker panel. Wait a full minute and then turn the power back on again. When the Soundbar reboots, it should be working.
