/** @defgroup Audio_Output_Host_18xx43xx Audio Output Host
 * @ingroup EXAMPLES_USB_18XX43XX
 * <b>Example description</b><br>
 * This example implements an audio interface class host mode device that enumerates
 * an audio interface class device (USB speakers) and sends samples to the device.
 *
 * The samples are created by a simple square wave generator in a timer ISR and
 * shipped out the streaming isochronous output pipe when a button is pressed on
 * the board.
 * When the example is first run the terminal window will display:
 * Audio Output Host Demo running.
 *
 * When the USB speakers are plugged in the terminal window will display:
 * Audio Device Enumerated.
 *
 * When the button is pressed on the board the USB speakers will produce
 * a loud tone. When the button is not pressed the USB speakers will be silent.
 *
 * When the USB speakers are unplugged the terminal window will display:
 * Device Unattached.<br>
 *
 * <b>Special connection requirements</b><br>
 * For Keil 1858 and 4357 boards, the host examples requires an external power supply
 * via the PWR power connector.<br>
