Find Out Which Device Is Having Problem

It is important to detect the source of the problem first. If the wireless connection is not established, the problem may be on one of the two devices you are trying to connect. 

Try connecting your TV or soundbar to another device to test if the wireless connection works. It will save you a lot of time and effort detecting the issue and help you figure out the right solution.

Reset Your Devices

If you cannot detect the problem, the simplest solution you should try is to reset your Vizio TV and soundbar. 

Rest assured that all your settings won’t be lost after resetting. It will only restore your devices to their original condition and clear the technical errors. 

Use the remote or power switch to turn off your devices. Then unplug them from the power outlet and all types of connections. 

You should wait at least ten minutes before reconnecting them to the power outlet. Now plug the wires into the connecting ports and switch the two devices on.

Check The HDMI Input

After you have identified the source of the problem, try to examine the ports on your device. 

There are multiple connector inputs on the back of your TV or soundbar. Only one of them supports the ARC connection.

Ensure that you choose the right input, which is labeled “HDMI 1 (ARC)” on the TV and “HDMI OUT (ARC)” on the soundbar. 

If the ports on your device have different labels, try to search for the name of your product on Google.

Check The Cable

Try to plug your cable into another port. If the connection is still unavailable, the cable has likely broken down. 

After checking the  ports, move on to examine the physical conditions of your cables. Make sure that you use the right HDMI cable with ARC input. 

If your cable’s end and wire are damaged or scratched, replace a new one from a local or online store. 

Turn On CEC

On your TV, Open “Menu”> “System”. 

Turn on “CEC” and “ARC (SAC)”, then activate “Device Discovery,” and the TV will search for the signal from your soundbar.
