# llPlaySoundSlave

*LSL function*

```lsl
void llPlaySoundSlave(string sound, float volume);
```

- `string sound`: Name of a sound in the prim's inventory, or a UUID.
- `float volume`: Volume level to set, between 0.0 (silent) and 1.0 (loud).

- Energy: 10

Plays the attached sound once at volume, synchronized to the next loop point of the most audible active Sync Master.

Plays attached **sound** once at **volume**, synced to next loop of most audible sync master declared by [llLoopSoundMaster](/functions/llLoopSoundMaster/).

```lsl title="How to use" frame="terminal"
llPlaySoundSlave("", 0.0);
```

## Caveats

- As an object can only have a single active sound, this function should be called from a different prim than the one that defined a sync master, otherwise it will remove the master sound, and no sound will be available to sync-to.
- This function is affected by the [Sound Queueing](/functions/llSetSoundQueueing/) property of the parent prim - this means it's possible to queue a slave sound prior to starting a master, without having to use more than one prim as an emitter. (See example on [llLoopSoundMaster](/functions/llLoopSoundMaster/)).

## Known issues

From the issue templates included by the wiki article:

- VWR-1574 (bug): llLoopSoundSlave and llPlaySoundSlave produce no sound.
