• Set the volume to 75% on the default sink:
  pamixer --set-volume {{75}}
• Toggle mute on a sink other than the default:
  pamixer --toggle-mute --sink {{ID}}
• Increase the volume on default sink by 5%:
  pamixer --increase {{5}}
• Decrease the volume on a source by 5%:
  pamixer --decrease {{5}} --source {{ID}}
• Use the allow boost option to increase, decrease, or set the volume above 100%:
  pamixer --set-volume {{105}} --allow-boost
• Mute the default sink (use --unmute instead to unmute):
  pamixer --mute
