No sound on Roku? Start with these steps

⚡ Fast fix

• Video but no sound? Start with the TV, not the Roku.
• Swap the HDMI cable. Audio problems often start there.
• Check audio settings on both devices. A wrong setting can mute everything.
• Picture is perfect, sound is gone? A bad HDMI port can affect audio without affecting video.

No sound on a Roku® can be especially frustrating because the picture often works perfectly. When that happens, it can be hard to tell whether the problem is the Roku, the TV, or the connection between them.

Asurion Experts help people troubleshoot streaming issues every day. We've rounded up the most common causes of Roku audio problems and the steps we recommend to get sound working again.

Is the audio problem coming from the Roku or the TV?

Before changing settings or replacing hardware, it's worth answering a simple question: can the TV produce sound from something else?

If you have another streaming device, game console, cable box, or any other audio source connected to the TV, try that first. If the TV plays sound normally from another device, the Roku becomes a much stronger suspect. If the TV has no sound regardless of the source, the problem may be happening somewhere else.

Another option is testing the Roku on a different television. It's a quick way to narrow down which device is actually causing the issue.

Check the Roku and TV audio settings

Audio settings can change after updates, new device installations, or even accidental button presses. In some cases, the Roku and TV are simply trying to use different audio formats or outputs.

Start by checking:

• Roku audio settings.
• TV audio settings.
• Audio output selections.
• Sound modes or advanced audio options.

We're often surprised by how many "no sound on Roku" complaints end up being a settings mismatch rather than a hardware problem.

Check the HDMI cable

HDMI cables don't always fail completely.

One thing we've run into over the years is a cable that still carries video perfectly but struggles with audio. That's what makes HDMI-related sound problems so frustrating—the picture looks fine, which makes the cable seem innocent.

If you have a spare HDMI cable available, swap it in and test again.

Test a different HDMI port

The cable isn't always the culprit.

We've also seen HDMI ports develop problems that affect audio while continuing to display video normally.

If your TV has multiple HDMI inputs, move the Roku to a different port and see if the sound returns.

Check for Roku and TV updates

If you've already checked settings, cables, and ports, make sure both the Roku device and the TV are running the latest available updates.
