Causes of Vizio Soundbar No Sound HDMI ARC

Vizio soundbar HDMI ARC doesn’t have optical digital audio out but with the digital optical output. According to my research, a common problem with Vizio Soundbar HDMI ARC is that it won’t work when connected to the HDTV. Here are the most common causes of the issue.

• Vizio Soundbar wasn’t properly installed or set up.
• Some foreign objects plug into the ARC HDMI port on the TV.
• Hinder the connection between the Soundbar and TV.
• Inadequate HDMI jack on the Soundbar.

The Techniques for Resolving VizioSoundbar HDMI ARC Problems:

If you have ever experienced a problem where none of the HDMI devices on your Vizio soundbar work after turning it on. Don’t worry! Some easy techniques are available to assist you, and they could potentially eliminate your Vizio arc issues.

1. Install or Setup Vizio Soundbar Properly

Vizio soundbars are available in various sound quality options, ranging from good to excellent. So, if your Soundbar doesn’t work, you probably did something wrong.

Go over the steps carefully when you have never set up a Vizio soundbar before. If you installed your Soundbar on a wall, make sure nothing stops the satellite speakers from outputting any sound.

2. Check Internet Connection

 When you have a slow internet connection, streaming audio from the Soundbar could affect you. You should contact your Internet service provider or network if there is a problem.

You can also see if your Vizio soundbar has any updates available, as these can fix issues with certain apps and software. Alternatively, you can try disabling Wi-Fi in your Vizio TV’s settings and then reactivating it.

3. Try Different HDMI Cables

If all your HDMI devices connect directly to the TV, try using a different HDMI ARC cable. The most common issue with HDMI cables is that the signal is too weak for the Soundbar to pick up.

 It might be better to use a different cable such as an optical or RCA amplified one. If you use an optical cable, it will have a higher output signal than an HDMI cable. It could prevent issues and ensure your Soundbar can pick up and play all your audio sources, not just one.

4. Select Right HDMI ARC Port

Try another port on your Vizio soundbar if none of the steps listed above successfully resolve your issues. It could be that the HDMI plug or cable that you are using is not compatible with the Soundbar and TV.

You can go to Vizio’s website and click on Help & Settings to fix this issue. To get better sound and better picture quality, you can now select a different HDMI port.

5. Update Your Vizio Soundbar Firmware

 The easiest way to resolve the Vizio HDMI ARC not working with any audio device is to update the device’s firmware. To find out if there is a firmware update on your Soundbar, you can follow the steps below:

• Turn off your Soundbar and unplug it from your TV.
• Press the “Menu” button on the Soundbar and go to Setup Mode.

Select Menu > Audio > System Information.

• Look for an icon with the label “Firmware” or a red exclamation mark that reads “Need Update.”

6. Enable CEC

CEC is almost obviously enabled on both your TV and Vizio Soundbar HDMI ARC. It can disable the ARC functionality on your Vizio soundbar for some reason.

To fix this:

• Turn both of your devices off entirely, and then wait a few minutes.
• Once the process is complete, plug your devices back in and wait for them to load.
• Go into the settings on both items and enable CEC again from there.
