# setSubscribeToTracksAutomatically()

> Enables or disables automatic subscription to all participant tracks.

`setSubscribeToTracksAutomatically(enabled)`

<Badge color="red">{"✗"} Prebuilt</Badge> <Badge color="green">{"✓"} Custom</Badge>

Toggles automatic track subscription during a call. When enabled, Daily automatically subscribes to audio, video, and screen tracks from all participants. When disabled, no new subscriptions are created automatically — you manage subscriptions manually via [`updateParticipant()`](/reference/daily-js/instance-methods/update-participant).

Must be called while in a call. To start a call without subscribing to any tracks, set [`subscribeToTracksAutomatically: false`](/reference/daily-js/types/daily-call-options#param-subscribe-to-tracks-automatically) at call creation time.

<Note>
  Track subscriptions only apply over SFU connections. In P2P calls, all tracks are always received.
</Note>

## Parameters

<ParamField body="enabled" type="boolean" required>
  `true` to subscribe to all tracks automatically, `false` to manage subscriptions manually.
</ParamField>

## Return value

Returns `this` for chaining.

## Example

```javascript theme={null}
// Stop auto-subscribing, then selectively subscribe to specific participants
call.setSubscribeToTracksAutomatically(false);

call.updateParticipant(participantId, {
  setSubscribedTracks: { audio: true, video: true, screenVideo: false },
});
```
