Linux installation can work without pyaudio

[truedat101]

I didn't realize pyaudio was listed as a requirement. I was able to install on linux and run. mpg123 must be installed.

sudo apt-get install mpg123

You may want to list this in the documentation.

Ubuntu： sudo apt-get install libasound-dev sudo apt-get install python-pyaudio python3-pyaudio sudo apt-get install libportaudio2 portaudio19-dev mpg123

If the latest version of PyAudio is not available, install it using pip: pip install pyaudio

都安装一下，就通过了。
