Octoprint plugin to replace printer sounds M300 S2093 P120 with mp3 sound played by RPi over the audio jack via an active speaker of a small amplifier (the signal is not strong enough to drive a speaker)

1. add mp3 files to .octoprint/data/sound/ to overwrite or to add new keywords
2. add settings to config.yaml

plugins:
  sound:
    night_start: 20
    night_end: 6
    night_volume: 60
    nomute:
    - change
    - offset
    - save_offset
    - baby_up
    - baby_down
	

• nomute contains a list of sounds played even if the plugin is muted (via the "switch" plugin)

3. call M300 @keyword (for example) in your GCODE... Any keyword is allowed, and it would be matched against a list of MP3 files in the .octoprint/data/sound/ or plugin folder (e.g. keyword.mp3). If none is found, the default, .octoprint/plugins/sound/default.mp3, would be played.

The sound will be played at reduced volume night_volume% at noght (between night_start and night_end)

It can be muted via the "switch" plugin
