sounddevice报错问题

[lonelyman0108]

在win10默认情况下系统编码格式为gbk，在运行demo_toolbox.py时会报错：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc2 in position 6: invalid continuation byte

打开D:\Env\anaconda3\Lib\site-packages\sounddevice.py移动到573行，有相关报错的issue，更改为mbcs后错误变成：

UnicodeDecodeError: 'mbcs' codec can't decode bytes in position 0--1:xxxxxxxxxxxxxxxxxxx

运行python -m sounddevice会报相同的错误

按照上述步骤更改系统编码格式后重启，再次运行python -m sounddevice就没报错了
