How to connect Vizio soundbar to Roku TV?

To connect a Vizio soundbar to Roku TV, plug one end of an HDMI ARC cable into the HDMI ARC port of the soundbar. And the other end into the TV’s HDMI ARC port. You may also use an Optical cable to connect your devices. Or use a Bluetooth receiver to output audio from the Roku TV to your soundbar.

3 ways to connect Vizio soundbar to Roku TV


For the best audio quality output, connect your devices using HDMI ARC.

HDMI ARC works just like your typical HDMI connection. Except that it also transmits audio signals. Which allows you to output the audio from your smart TV to your soundbar.

Plus, it’s easy to set up. You just have to pick up an HDMI cable and plug it into your devices.

Tip: For better quality and bandwidth, get an HDMI 2.0 cable.

If you’re using one of the latest Vizio soundbars today, like M512x-J6

You may connect it to your Roku TV via HDMI eARC

It works the same with HDMI ARC. Except that it supports higher audio file formats such as Dolby Atmos and DTS:X.

Note: However, you must know that not all Vizio soundbars have an HDMI ARC port. So, if yours doesn’t have one, check the other connection options below.

Here’s a quick rundown on HDMI ARC/eARC connection:


  • Promotes less cable clutter.
  • Easy installation and setup.
  • Compatible with most smart devices.
  • Support most of the latest audio formats.


  • It isn’t available on older Vizio soundbar models.

To connect a Vizio soundbar to Roku TV via HDMI ARC/eARC

Do both of your devices support HDMI ARC/eARC connection? 

If yes, then let’s get started with the setup.

Follow these instructions:

Step 1: Turn on the Roku TV.

Press the POWER button on the TV remote once. After that, the TV screen should light up and display the homepage.

Step 2: Turn on the Vizio soundbar.

Make sure first that it’s plugged into a power socket. 

Then, press the POWER button on the device once. Look for the circle-with-a-slash icon on one of its sides.

You should see its LED lights glow. On some models, you may also hear a tune.

Step 3: Get a working HDMI cable.

There’s no such thing as an HDMI ARC cable. So don’t try hard looking for anything like that. A regular HDMI cable should work.

Step 4: Plug one end of the HDMI cable into the Vizio soundbar.

Look for the HDMI ARC/eARC port at the back of your Vizio soundbar. 

It usually has an “HDMI ARC” label on it. 

Plus, it has a green outline around the port. So, you shouldn’t have a problem looking for it.

Step 5: Plug the other end of the cable to the Roku TV.

Look for the HDMI ARC/eARC port on your Roku TV. It’s usually labeled as “HDMI ARC (Audio Out).” 

Take note of the “Audio Out” label. As plugging the cable into an “input” port would fail your connection setup.

Step 6: Change the Roku TV’s audio output.

The actual steps may vary depending on your TV model.

But here’s the usual way how to do it: 

Using your TV remote, press MENU. Then, select Settings>Audio>Audio Output>HDMI ARC/eARC.

Step 7: Change the Vizio soundbar’s input source.

Press and hold the INPUT button on the device for a few seconds. Or until the LED lights started flashing. Just search for a box-with-a-line icon.

Doing this puts your device into “Auto Input Search.”

Alternatively, press “INPUT” on the soundbar remote to select the correct input source.

#2: Via Optical cable

You may try this connection if your Vizio soundbar doesn’t have an HDMI ARC/eARC port.

Before HDMIs, users connect their devices using an optical cable.

Note: It’s also known as TOSLINK or SPDIF connection.

It works similarly with an HDMI connection. An optical cable output sounds from your smart TV to your soundbar.

The only difference is that it can’t support higher resolution audio formats such as Dolby Atmos. 

So, an optical cable connection is only good for regular movie or gaming streaming.

A quick rundown on Optical cable connection:


  • Has high bandwidth.
  • Fast and easy installment.
  • Works with most smart TVs and soundbars.


  • Don’t support higher resolution audio formats.

To connect a Vizio soundbar to Roku TV via Optical cable

Do you already have an optical cable to use? Then, let’s get started!

Follow the instructions below:

Step 1: Ensure that your devices are powered ON.

See if your Roku TV screen displays the homepage. And that your Vizio soundbar LED lights are glowing.

If not, make sure to turn on your devices first. 

Step 2: Connect one end of the optical cable to the Vizio soundbar.

Locate the optical cable port at the back of your soundbar. 

Look for an irregularly-shaped port with a square outline. Depending on your soundbar model, it’s either on the left or right side of the port panel.

Step 3: Connect the other end to the Roku TV.

Access the back panel of your TV to search for the optical cable port. Look for a port with a “Digital Audio Out (Optical)” or similar label. 

Again, take note of the “Audio out” label.

Step 4: Change the audio output of the Roku TV.

To do this, you must use your TV remote.

Press MENU, then go to settings. Select Audio>Audio Settings>Optical.

Suppose “Optical” isn’t on the options. Choose “TOSLINK” or “SPDIF.”

Step 5: Change the input source of the Vizio soundbar.

Grab the soundbar remote and press “INPUT.” Then, select “optical.”

Or you may also press and hold the INPUT button on the soundbar. And allow it to detect your Roku TV optical connection.

Now, try to play music on your TV. 

If you hear the sounds coming from your soundbar…

Then, you’ve successfully connected your devices via optical cable.

But if not, try to reconnect the optical cable. And redo the same process above. Suppose the problem persists. Try changing the cable.

You have to use third-party devices. Either a Bluetooth receiver or a smartphone that has a Roku mobile app.
