  77 Not all sampling rates will be supported by your hardware.
  78
  79 Leave the device name blank to choose deafult audio device. \
  80 ALSA users with audio trouble may try setting the device name to plughw:0,0
  81
  82 The audio sink can have multiple inputs depending upon your hardware. \
  83 For example, set the inputs to 2 for stereo audio.
