SetTimerEx("PlaySound",TIMEINMILISECS,false,"i",playerid);

//NOT inside any cmd or callback
forward PlaySound(playerid);
public PlaySound(playerid)
{
    for(new i = 0; j = GetPlayerPoolSize(); i <= j; i++) { // For player sound for all players
        PlayAudioStreamForPlayer(i,"******.com");
    }
}

Instead of "******.com" you need to insert a valid mp3, or another sound format, link
