## Community notes

**Killzone_Kid** — 2016-12-03

To transmit user custom sounds (see Multiplayer_Custom_Sounds_Tutorial), prefix the full filename including file extension with #. For example if there is a custom user sound file called `MySound.ogg`, to play it on the radio use:

```sqf
player customRadio [1, "#MySound.ogg"];
```
