Enable internal PC-Beep generation.
Divider = 00h - disables internal PC Beep
generation and enables normal operation of
the CODEC.
Divider not 00h - generates the beep tone
on all Pin Complexes that are currently
configured as outputs. The Azalia spec
states that the beep tone frequency =
(48 KHz Azalia SYNC rate) / (4*Divider),
producing tones from 47 Hz to 12 KHz
(logarithmic scale). Instead, this part
generates tones with frequency = 48000 *
(257 - Divider) / 1024, yielding a linear
range from 12 KHz to 93.75 Hz in steps of
46.875 Hz. If JackSenseVSR[Rate2x], then
the beep tones generated have frequency =
48000 * (513 - Divider) / 1024, yielding a
range of 24 KHz to 12093.75 Hz in steps of
46.875 Hz.
