   9  *  Audio demonstration application. This gives a simple reference
  10  *  application for implementing a USB Audio Output device using the
  11  *  basic USB Audio drivers in all modern OSes (i.e. no special drivers
  12  *  required).
  13  *
  14  *  On startup the system will automatically enumerate and function
  15  *  as a USB speaker. Incomming audio will output in 8-bit PWM onto
  16  *  the timer output (timer 3 for the AT90USBXXX6/7 USB AVRs, timer 1 for
  17  *  the AT90USBXXX2 controller AVRs) compare channel A for AUDIO_OUT_MONO
  18  *  mode, on channels A and B for AUDIO_OUT_STEREO and on the board LEDs
  19  *  for AUDIO_OUT_LEDS mode. Decouple audio outputs with a capacitor and
  20  *  attach to a speaker to hear the audio.
  21  *
  22  *  Under Windows, if a driver request dialogue pops up, select the option
  23  *  to automatically install the appropriate drivers.
