MMM-Sounds

This a module for the MagicMirror. It can play WAV sounds through your Pi when triggered by other modules.

This can only play WAV files.

Although this has been developed for the Raspbian operating system, any system that uses alsa would likely work too.

Prerequisites

1. Read this to configure sound output for your Raspberry Pi
2. Make sure alsa is installed on your Pi: sudo apt-get install alsa-base alsa-utils
3. Adjust your volume output, try 100% first with: alsamixer
4. Optional, test your speaker output: speaker-test -t sine -f 440 -c 2 -s 1

Module Installation

1. Navigate into your MagicMirror's modules folder and execute git clone https://github.com/jc21/MMM-Sounds.git
2. Execute cd MMM-Sounds && npm install to install the node dependencies.
3. Optional, test the alsa player with a wav file: aplay sounds/woop-woop.wav
4. Add config to your magic mirror config file

Using the module

To use this module, add it to the modules array in the config/config.js file:

modules: [
	{
		module: 'MMM-Sounds',
		config: {
			startupSound:   'wobble.wav',
			quietTimeStart: '23:00',      // 11pm
			quietTimeEnd:   '07:00'       // 7am
		}
	}
]

Configuration options

The following properties can be configured:

Option	Description
startupSound	The sound to play after module startup Possible values: string Default value: null
defaultDelay	The default delay before playing the file in milliseconds Possible values: integer Default value: 10
quietTimeStart	The 24 hour and minute start of Quiet time Possible values: string Default value: null
quietTimeEnd	The 24 hour and minute end of Quiet time Possible values: string Default value: null
debug	Enable to display more debug messages in console Possible values: bool Default value: false

Quiet Times

This module supports not playing sounds during a quiet time, if BOTH the quietTimeStart and quietTimeEnd config options are specified.

The values for these times are HH:mm and must be in 24 hour format. Examples:

• 00:30 - 12:30am
• 06:30 - 6:30am
• 14:11 - 2:11pm
• 23:30 - 11:30pm

Telling the module to play sounds from another module

From another module you can tell this module to play a sound in 2 ways:

In your module:

this.sendNotification('PLAY_SOUND', 'wobble.wav');

or also specifying a delay:

this.sendNotification('PLAY_SOUND', {sound: 'wobble.wav', delay: 1000}); // 1 second delay

Included sounds

• buzz.wav
• sonar.wav
• ta-ting.wav
• twip.wav
• wobble.wav
• woop-woop.wav
