Accessibility: Enabling and Testing Audio Description Tracks on Different Devices

Audio description (also called descriptive audio) adds spoken narration of key visual elements—like actions, scene changes, and on-screen text—to help viewers who are blind or have low vision follow along. As audio description becomes more widely offered by streaming services and broadcasters, it helps to know how to enable and verify these tracks on the devices you use most.

This guide walks through practical steps for enabling audio description across common streaming devices and smart TVs, how to test that it’s working, and troubleshooting tips when it isn’t. Because menu names and system behavior can vary by model, app version, and region, treat the steps below as a reliable starting point and check the manufacturer or service documentation if something looks different on your device.

Quick overview: where audio description lives

• Audio description is usually an alternate audio track in a video player, similar to a language track. It may be labeled “Audio Description,” “Descriptive Audio,” “AD,” or appear as an extra language option.
• Some platforms also offer a global accessibility toggle that enables audio descriptions whenever available.
• Availability depends on the content and the streaming app. Not every show or movie has an audio-description track.

Devices covered

This article provides guidance for:

• Roku streaming players and Roku TV
• Amazon Fire TV devices
• Apple TV (tvOS)
• Android TV / Google TV devices (including Chromecast with Google TV)
• Smart TVs (Samsung, LG, Sony and others)
• Tips that also help when using soundbars, AV receivers, or HDMI passthroughs

How to enable audio description — general steps

1. Play a title that includes an audio description track. (If you are unsure whether a title includes AD, check the streaming service’s details or search within the app for “audio description” or “descriptive audio”.)
2. While playback is active, open the player’s audio or subtitles/options menu. This is often available as an on-screen icon (speech bubble, audio, or a three-dot menu) or via your remote’s options button.
3. Look for an audio track labeled with “Audio Description,” “Descriptive Audio,” or similar. Select it.
4. If you prefer AD whenever available, some devices and apps include a system or app-level accessibility setting that can be turned on to default to descriptive audio when present.

Because menu names and button locations differ, below are device-specific instructions that illustrate typical navigation.

Roku: enabling and testing audio description

Typical steps (may vary by model and Roku OS version):

• During playback, press the star (*) or OK/options button on your remote to open the player menu. Look for “Audio” or “Language” options.
• If an audio description track is available it will usually appear among the audio languages as “Audio Description” or a similar label. Select it.
• Some Roku models also provide a global Accessibility menu: go to Settings > Accessibility. There may be an “Audio Guide” or other accessibility features—note that the Audio Guide is a screen reader and not the same as audio description for video. Check your Roku support page for current labeling.

Testing tips for Roku:

• Choose a title you know has descriptive audio (check the streaming app’s details). Switch to the AD track and listen for extra narration describing visual elements.
• If you don’t see an AD track in the player, make sure the streaming app supports AD on Roku and the content includes it.

Amazon Fire TV (Fire TV Stick, Fire TV Cube)

Typical steps (may vary by device and firmware version):

• Start playback in your app. Press the menu or options button (three-line button or on-screen three-dot menu). Open Audio & Subtitles or the player’s audio selector.
• Select the audio track labeled “Audio Description,” “Descriptive Audio,” or similar.
• Fire TV also has a system accessibility area under Settings > Accessibility where some devices let you enable descriptive audio globally—this varies and may be called “Audio Description” or another accessibility label.

Testing tips for Fire TV:

• If an AD track is missing, confirm the streaming app supports AD on Fire TV. Updating the app and the Fire OS firmware can resolve missing player features.

Apple TV (tvOS)

Typical steps (may vary by tvOS version):

• During playback, swipe down on the Siri Remote or press the remote’s touch surface to display the Info panel, then choose the Audio tab.
• Look for an audio track labeled with “Audio Description” or “Descriptive Audio” and select it.
• You can enable audio descriptions system-wide: Settings > Accessibility > Audio Descriptions. When this is toggled on, tvOS should automatically switch to AD when it’s available for content.

Testing tips for Apple TV:

• If AD doesn’t activate automatically even with the setting enabled, try manually selecting the AD track from the Audio tab while the content is playing.

Android TV and Google TV (including Chromecast with Google TV)

Typical steps (may vary by manufacturer and OS version):

• While a video is playing, open the player’s audio/subtitles/options menu (often a three-dot or speech-bubble icon).
• Select the AD track if it appears as “Audio Description” or “Descriptive Audio.”
• Some devices offer a global setting under Settings > Accessibility > Audio Description or similar.

Testing tips for Android/Google TV:

• Ensure the streaming app supports AD on Android TV/Google TV. Also check app permissions and updates if options don’t appear.

Smart TVs (Samsung, LG, Sony, Panasonic, etc.)

Smart TV platforms vary widely. In many cases audio description is available either:

• From the video player’s audio/subtitle options during playback; or
• From the TV’s accessibility settings as a system toggle that instructs apps to use AD when available.

Typical steps to try:

1. Start the app and play a title that may include descriptive audio.
2. Open the on-screen player menu and go to Audio or Language options.
3. Select the track labeled “Audio Description,” “Descriptive Audio,” or similar.

Testing and tips for smart TVs:

• If you use an external streaming stick or set-top box plugged into the TV, try enabling AD on the streaming device rather than the TV, since the streaming app runs on the external device.
• If your TV’s audio output is set to an external receiver or soundbar and the AD track doesn’t play, check audio output formats (e.g., PCM vs. passthrough) and consult the TV/AV receiver manuals—some audio passthrough modes can change how alternate audio tracks are handled.

How to find content with audio description

• Many streaming services label descriptive audio in the title details or list it under audio/subtitle options on the title page. Search within the service for “audio description” or “descriptive audio.”
• Some providers maintain a catalog or filter for audio-described titles; check the help center of the specific service.

Testing checklist: quick verifications

1. Confirm the title includes an AD track (service help, title details, or a known AD-labeled title).
2. Play the content and open the audio track/options menu.
3. Select the AD/descriptive audio track and listen for narration of visual elements.
4. If nothing changes, try manually toggling the device’s accessibility setting (if available) and reloading the app.
5. Update the streaming app and the device firmware.
6. If using external audio equipment (AVR, soundbar), temporarily connect TV speakers directly to rule out passthrough issues.

Troubleshooting common issues

• No audio description option visible: Confirm the content supports AD and that the streaming app supports AD on that device. App or firmware updates may be needed.
• AD plays but is low or mixed with other audio: Check audio output modes. Some surround-sound passthrough settings can route AD differently; try switching to stereo/PCM to test.
• AD toggles off after switching titles: Some players revert to default audio for each title; enabling a system-level Audio Descriptions setting (if available) can help.
• Confusion between “Audio Guide” and “Audio Description”: On some devices, “Audio Guide” refers to a screen reader feature for navigating menus, not descriptive narration embedded in video. Verify which feature you’re using.

Practical comparison (typical places to find AD controls)

Note: Table rows indicate typical locations; manufacturers may change menu names and options.

When to contact the streaming service or manufacturer

• If a title clearly listed as having audio description doesn’t show an AD track on multiple devices, contact the streaming service’s support.
• If the app works on one device but not another (for example AD is present on a phone app but missing on your TV), check the device’s firmware and app version, then contact the device manufacturer if updates don’t help.

Accessibility etiquette and expectations

• Audio description availability varies by content licensing, region, and the streaming service’s content library. Don’t expect every title to include it.
• When it’s available, audio description should provide concise narration between dialogue—expect variations in length and delivery depending on production choices.

FAQ

Q: What’s the difference between audio description and a screen reader (audio guide)?
A: Audio description is narration embedded in a video track that describes on-screen visuals. A screen reader or audio guide speaks the interface (menus and text) to help people navigate a device or app. Both are accessibility features but serve different purposes.

Q: Why does audio description sometimes disappear when I switch devices or outputs?
A: Changing devices, HDMI inputs, or audio output modes can change how a player exposes audio tracks. Switching to stereo/PCM or disabling certain passthrough modes can help reveal AD tracks. Also ensure the app and device firmware are up to date.

Q: My hearing-impaired family member needs captions and I need audio description—can both be on at the same time?
A: Many players support captions and an AD audio track simultaneously. In some apps you can enable subtitles/closed captions while selecting the AD audio track. Behavior can vary by app and device.

Q: I can’t find descriptive audio in my region—why?
A: Content and features sometimes vary by region due to licensing and localization. Check the streaming provider’s help pages for region-specific availability.

Q: Are audio descriptions required by law?
A: Legal requirements vary by country and platform. Some jurisdictions encourage or require broadcasters and providers to make content accessible, but the specifics differ. For precise guidance, consult local regulations or official resources.

Disclosure

Settings, menu names, and compatibility can differ by TV model, streaming device, operating system and firmware version, app version, and region. If steps above don’t match what you see, consult the device or service documentation for the most up-to-date instructions.

Conclusion

Enabling and testing audio description is usually straightforward once you know where to look: the player’s audio or options menu during playback, or a system-level accessibility toggle when available. If you can’t find an AD track, check whether the title supports it, update your app and device, and try alternate audio output settings.
