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 HD Audio specification states that the beep tone:
frequency = (48 KHz HD Audio 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.
