es.playsound无法加载声音

Question

尝试加载简单的声音会导致错误：无法加载声音。我有另一个脚本设置相同的方式，但不起作用。到底是怎么回事？我在下面给出了完整的（简单）脚本。

# Eventscripts Imports
import es, playerlib

def load():
    print 'You have loaded Chicken Sh1t'

def unload():
    print 'You have un loaded Chicken Sh1t'

def download():
  es.stringtable('downloadables', 'sound/mysounds/chicken.wav')

def player_say(ev):
    alive_ts = es.getlivingplayercount(2)
    alive_cts = es.getlivingplayercount(3)
    if ev['text'] == 'chicken':
        if alive_ts == 1:
            if alive_cts == 0:
                useridlist = es.getUseridList()
                for usrid in useridlist:
                    es.playsound(ev['userid'], 'sound/mysounds/chicken.wav', 1)

任何人都可以帮助我吗？
