关于Python使用playsound模块播放音频文件的编码问题UnicodeDecodeError: 'utf-8' codec can't decode byte 0xce in position

由于项目的需要，需要播放声音。做过一些尝试，最简单的os.system(file)，播放，出现错误提示一串乱码。
之后改成playsound尝试，刚开始几次效果不错。能直接播放，代码简单而优雅。之后出现的问题就让我悲剧加尴尬了。直接上我的代码和错误提示吧。

测试代码

from playsound import playsound

playsound('chuku.wav')

错误提示

错误提示
UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xce in position 0: invalid continuation byte

出了问题得解决呀，所以第一时间使用搜索引擎来辅助我解决问题，搜遍百度，竟没有一个这种先例。这时有点失落了。
根据系统的错误定位，我们来看看源码是什么情况吧。

    def winCommand(*command):
        buf = c_buffer(255)
        command = ' '.join(command).encode(getfilesystemencoding())
        errorCode = int(windll.winmm.mciSendStringA(command, buf, 254, 0))
        if errorCode:
            errorBuffer = c_buffer(255)
            windll.winmm.mciGetErrorStringA(errorCode, errorBuffer, 254)
            exceptionMessage = ('\n    Error ' + str(errorCode) + ' for command:'
                                '\n        ' + command.decode() +
                                '\n    ' + errorBuffer.value.decode())
            raise PlaysoundException(exceptionMessage)
        return buf.value

winCommand这个函数出错了
其中，
errorCode = int(windll.winmm.mciSendStringA(command, buf, 254, 0))，这一句代码出错了。抱歉，我看不懂是什么原因，还望大神来帮忙看看
最后插入全部的playsound代码，供各位大神分析，谢谢大家了。
