UnhandledPromiseRejectionWarning: Error: FFmpeg/avconv not found!

You can safely ignore the warning, it is because you do not have ffmpeg installed on your system. If you want to get rid of the warning, installing ffmpeg would solve it.

I had removed ffmpeg as a system dependency from the readme since ffmpeg-static exists under node_modules, however it discord.js seems to be looking for a system level dependency to play the audio initially, I'll update this in the readme sometime soon!

For me when I ignored the warning, the bot was crashing with the following stack trace :

I had to comment the line of code that play a sounds (on enter/exit) to make it work without installing ffmpeg.
