This command can be used to have all clients on a channel play a certain sound. Please note that the sound file must be present on the user's system to be able to play it, so don't use this randomly as nobody will hear a thing when the submitted filename is not found.
Examples:
`/SOUND Burp'
Will play the soundfile BURP.WAV on all user's system, if found!
`/SOUND Burp Excuse me!'
Will play the soundfile and send the text 'EXCUSE ME!' with it.
