# Type Alias: LensVideoPlaybackMutedError

> **LensVideoPlaybackMutedError**: `NamedError`\<`"LensVideoPlaybackMutedError"`\>

This error occurs when a Lens attempts to play video, but the browser blocks audio playback due to autoplay policies.
The video will still play, but in a muted state.

Applications should handle this error by showing an unmute button or similar UI element,
allowing the user to interact with the page and then unmute audio.

```ts
cameraKitSession.events.addEventListener('error', ({ detail }) => {
  if (detail.error.name === 'LensVideoPlaybackMutedError') {
    // Show an unmute button that calls session.unmute() on user interaction
    unmuteButton.style.display = 'block'
    unmuteButton.onclick = () => {
      cameraKitSession.unmute()
      unmuteButton.style.display = 'none'
    }
  }
})
```
