# AVSampleBufferAudioRendererWasFlushedAutomatically

A notification the system posts when a renderer flushes its enqueued media data without an explicit request to do so.

```
static let AVSampleBufferAudioRendererWasFlushedAutomatically: NSNotification.Name
```

## Discussion

A renderer may flush enqueued media data when the user routes playback to a new destination, or when you change the playback rate of the attached <doc://com.apple.documentation/documentation/AVFoundation/AVSampleBufferRenderSynchronizer>. No flush occurs for normal pauses and resumes.
