You've invested in a soundbar so you can treat your ears to that crisp, movie theater-worthy audio you've been craving. But when you connect it to your TV and turn on your favorite movie, you only hear silence. You jiggle the HDMI ARC cable, but still nothing. Not exactly the result you were going for.

At Asurion, our experts know it's not always easy to set up audio equipment, but we're here to help. From connecting a soundbar to shopping for tech care plans, we've got you covered. This guide walks you through how to fix no sound from a soundbar using HDMI ARC.

Understand how HDMI ARC works

A standard HDMI connection sends video and audio from one device to another. For example, you may use an HDMI cable to connect your laptop to your TV so you can watch YouTube® videos on the big screen. However, a regular HDMI cable is a one-way road. It can't send audio back out from the TV, only to it.

The HDMI Audio Return Channel (ARC) lets audio travel from the TV to other devices and vice versa. It works hand in hand with HDMI Consumer Electronics Control, allowing you to connect compatible devices and control them with a single remote. That way, you don't need to juggle multiple devices every time you want to blast the Interstellar soundtrack.

So how does the audio magic happen? When you connect your TV and HDMI-CEC soundbar, they do a metaphorical handshake. That means they swap information about the audio formats they support and how to control them. If there's an HDMI ARC handshake issue, the TV doesn't send audio to the soundbar, leaving you on mute.

Check and reset HDMI ARC connection

Are you running into audio problems using the HDMI ARC connection to your soundbar? These tech tips may help you fix the HDMI ARC sound.

Use the right HDMI ports

Soundbar cable problems are one of the most common reasons audio doesn't work. Double-check that you've plugged the cable into your TV's ARC HDMI port, not a standard one. Then check your soundbar HDMI connection, too.

Check your TV's audio output

Sometimes, your TV may not automatically turn on the HDMI ARC settings when you plug in a soundbar. Open the settings and make sure the TV's audio output is set to ARC. The exact buttons vary by device, but you'll probably find this under something like Audio System or, if you're using an Apple TV, by selecting Video and Audio > Audio Output.

Turn on CEC

If you're still experiencing TV soundbar ARC issues, HDMI-CEC may be the culprit. Without it, your soundbar and TV can't talk to each other.

To fix this issue, go into your TV's settings and enable CEC. Depending on the brand, this feature may be called Anynet+®, Bravia Sync®, or SimpLink®. If you're unsure, check your TV's manual or reach out to the manufacturer or a tech help team.

Unplug and reconnect your devices

For a simple home theater audio fix, try switching off your soundbar and TV and unplugging them. After a few seconds, power on the TV, followed by the soundbar, and connect them again with the HDMI cable. Sometimes that's all it takes to reset the handshake and solve soundbar ARC connection problems.

Resolve compatibility and firmware issues

Still dealing with soundbar HDMI ARC problems? Don't say goodbye to your dream home theater just yet. Try these more advanced ARC audio troubleshooting tips:

• Update your TV firmware: An outdated TV may not communicate properly with your soundbar setup. Click Settings > System to check for pending software updates.
• Check if your TV is compatible with eARC vs ARC sound: If you've splurged on a premium soundbar, it may use enhanced ARC (eARC) instead of the regular channel. If your HDMI ARC is not working, make sure your TV and soundbar use the same setup.
• Try using optical audio instead: As a temporary workaround, consider using an optical (TOSLINK) cable to connect your TV to the soundbar. It won’t deliver the same experience as ARC, but it will restore sound while you troubleshoot.
