Playing a sound

From the command-line

luna-send -n 1 palm://com.palm.audio/systemsounds/playFeedback '{"name":"shutter"}'

Inside a mojo app

this.controller.serviceRequest('palm://com.palm.audio/systemsounds', {
    method:"playFeedback",   parameters:{ name: 'shutter' }
 });

Where shutter equals the file name, minus the extension, of a file found below.

Notes:

  • Replacing or placing new file in this directory requires a restart of pulseaudio:
root@castle:/# initctl stop pulseaudio; initctl start pulseaudio
  • Pulseaudio seems to favor the .pcm extention if there are similarly named files. For example, shutter.pcm vs shutter.wav.
  • Compatible file types: .pcm, .wav
  • Incompatible file types: .mp3
