Method 1: How to Connect Vizio Soundbar To Roku TV With Optical Cable

Method 1: Connecting Vizio Soundbar To Roku TV With Optical Cable

An optical cable comprises several small strands of polished plastic specifically designed to transfer light. In an optical connection, digital audio signals are transmitted through pulses of light.

In short, the optical cable connection simply outputs sounds from your TCL Roku TV’s Optical output port to your Vizio sound bar’s optical input port. An optical connection gets the job done in most cases. You can also enjoy your favorite TV series and binge your Saturday shows.


  • The installation is simple and easy.
  • The audio signal bandwidth is high.
  • The Optical port is a simple plug-and-play system.
  • The optical connection is immune to electrical interference, so you wouldn’t experience any hissing sounds from your Vizio soundbar.
  • The signal strength holds up better over longer distances as well.


  • Optical connection does not support the latest high-resolution audio format like Dolby Atmos, Dolby Digital, Dolby Digital Plus, surround sound, etc.
  • In a surround sound setup like a 2.1, 5, or 7.1 channel speaker array, the optical connection wouldn’t provide you with the surround sound experience.
  • The optical wire is also fragile and has a high chance of breaking.
  • The optical connection method is suitable mainly for casual users.
  • An optical cable compatible with your TCL Roku TV and Vizio soundbar is required.

Steps To Connect

  • Turn on both your Roku TV and Vizio soundbar. The TV will display the homepage, and the Vizio soundbar will have its LED lights glowing.
  • Connect the optical cable to your Vizio soundbar’s optical input.
  • Connect the other end to the Digital Audio Out (optical output) port of your Roku TV. You can also look at the manual to find out the optical port.
  • Set the output of your Roku TV to optical/SPDIF/TOSLINK (whichever is available) from the audio settings in the menu.
  • Press the INPUT button on your Vizio soundbar remote.
  • From the INPUT options, select the Optical option.

And an optical connection will be established between your Vizio soundbar and TCL Roku TV.

Method 2: Connect Vizio Soundbar To Roku TV Via Bluetooth 

Method 2: Connecting Vizio Soundbar To Roku TV Via Bluetooth

Trust me, connecting via Bluetooth is the easiest method. This is a wireless setup, so you don’t have to deal with messy cable clutter running from your TV to the soundbar. Bluetooth connection gives an overall clean and aesthetic look to your setup. 

The only con would be the initial setup and maybe the cost of devices. You’d have to buy a Bluetooth receiver that will connect your TCL Roku TV and Vizio soundbar. There can also be latency issues in the audio transmission if the receiver quality is not on par. 

Steps To Connect

  • Bluetooth receivers can be battery-powered as well as directly wall-powered. If yours is battery-powered, ensure that its battery is charged. If it’s the other type, plug it directly into the wall.
  • Turn on your Roku TV and Vizio soundbar.
  • Plug the receiver into the RCA or AUX port (this will establish an Analog connection) of your Roku TV, which has an Audio Out label. This will establish a connection between your TV and the Bluetooth module.
  • Change the audio output of your Roku TV to Bluetooth from the audio menu in settings.
  • Press the Bluetooth icon on your Vizio soundbar to pair it with the Bluetooth receiver. The soundbar connection will be established with the Bluetooth receiver, and the connection between your Roku TV and the Vizio soundbar will be established.

You can also use the Roku mobile app if the Bluetooth method doesn’t work.

Pro Tip

Invest in a good Bluetooth receiver. Cheap Bluetooth receivers usually have poor build quality and can cause an audio sync issue between your TCL Roku TV and the Vizio soundbar.

And they may also have short battery life. You can also go for a two-in-one Bluetooth receiver and transmitter as a whole. They are generally of good quality and can be used for other purposes.

Method 3: Connecting Vizio Soundbar to Roku TV With HDMI  

Method 3: Connecting Vizio Soundbar to Roku TV With HDMI

A High Definition Multimedia Interface (HDMI) is a wired connection, and it is probably the best option if you want the best audio quality compared to other audio connections. HDMI is an HD signal that is very common these days.

A single cable can transfer both high-definition video and audio between connected devices. The HADI ARC (Audio Return Channel)/ eARC technology of HDMI is similar to standard HDMI, plus it transmits impressive sound.


  • Support for Dolby Atmos and DTS-X surround sound.
  • Easy installation and setup.
  • Widely compatible with modern devices.


  • Non-availability of the HDMI ARC connection port on your TCL Roku TV or Vizio soundbar.
  • Not all the platforms and media support Dolby Digital, Dolby Atmos, DTS-X, or surround sound.
  • Before connection, you should already have an HDMI cable.  

As for buying an HDMI cable, there’s no need to get some high-end HDMI cable that promises a lot of fancy codecs; just a standard HDMI 2.1 cable would work.

Steps To Connect

  • Turn on your Roku TV and Vizio soundbar.
  • Locate the HDMI ARC/eARC (Audio out) port at the back of your Roku TV and connect the HDMI cable to that port.
  • Connect the other end to HDMI ARC or a similarly labeled port on your Vizio soundbar.
  • Set the input of the soundbar to HDMI ARC with the Vizio soundbar remote controls.
  • Change the audio output on your Roku TV to HDMI ARC from the audio menu, or use your Vizio soundbar’s “Auto input search” feature.

Pro Tip

Search for CEC in your TV menu. If it’s available, turn it on. And similarly, search for eARC, and if it’s available, turn it on. It’ll give you DTS-X surround sound support. Give more priority to the eARC connection as it offers superior sound quality.

FAQs on Connecting Vizio Soundbar to Roku TV

Q. Why isn’t my Vizio soundbar connecting to my Roku TV?

There can be many reasons why your Vizio soundbar isn’t connecting to your TCL Roku TV. Some of the reasons can be:

The devices, i.e., your TCL Roku TV, Vizio soundbar, and Bluetooth receiver (if you’re using the Bluetooth method), are not working well. They have some malfunction or manufacturing defect.

The connecting cables, i.e., HDMI or optical cables, are not working. They can either be broken or have a loose connection with the ports. Try switching them to new ones as the cables could also be defective.

If you’re using the Bluetooth method, your Roku TV or Vizio soundbar may not be compatible with the Bluetooth receiver. 

The HDMI/Optical cable may not be plugged into the correct port, i.e., the HDMI ARC/eARC (Audio Out) port of your Roku TV and the input port of your Vizio soundbar.

The Auto-detection feature of Roku TV may not be able to recognize the Vizio soundbar. So try doing it manually.

Q. What is the input button on the Vizio sound bar?

The input button on the Vizio sound bar is used to switch between audio sources. For example, if you press the INPUT button on your Vizio soundbar remote, it’ll switch the audio input between sources like optical, HDMI, or Bluetooth.

Q. Where is HDMI ARC on Roku TV?

The HDMI ARC port is generally located at the back of your TCL Roku TV. You can look for the port labelled “HDMI® ARC” (or similar). 

Q. Does my Roku TV have Bluetooth?

You can go to the menu screen and look for Bluetooth in the connections or settings tab. If you find a Bluetooth connection option, your Roku TV has Bluetooth.

But the in-built Bluetooth of your Roku TV works only with other Roku devices like Roku streaming devices or another TCL Roku TV. You can also visit the official website.

Search for your Roku TV by its model number and go to its Product Documentation/specification to find out if it has Bluetooth.
