 * To make a noise, call audiobell(dev, pitch, period, volume, poll).
 * dev is a device_t for the audio device to use.
 * pitch is the pitch of the bell in Hz,
 * period is the length in ms,
 * volume is the amplitude in % of max,
 * poll is TRUE if we may not block or use interrupts.
 *
 * This function is designed to be passed to pckbd_hookup_bell() and
 * equivalents.
