# EnableAudioTrack(ushort, bool)

> Enable/disable audio track decoding. Only effective when the VideoPlayer is not currently playing.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine.Video](/engine/6000.0/script-reference/unityengine/video.md)
* **Assembly:** UnityEngine.VideoModule

```csharp
public void EnableAudioTrack(ushort trackIndex, bool enabled)
```

### Parameters

**** (\[ushort]\(https\://learn.microsoft.com/dotnet/api/system.uint16)): Index of the audio track to enable/disable.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): True for enabling the track. False for disabling the track.

### Remarks

Disabling audio tracks helps save processing resources by disabling audio decoding completely. This is different to muting a track during playback, which turns the audio track volume to 0 but still decodes the audio samples.
