self.play_args = play_args or ["paplay"]

In the above code, play_args can override the default of ["paplay"], but it comes from the __init__() kwargs. Since self.config can't be accessed in a plugin until super().__init__() is called, it's not possible to pass this configuration from a plugin config.

Ideally the default would be the global player instead of hardcoded paplay to allow for other playback systems
