Enable internal PC-Beep generation.
Divider = 00h - disables internal PC Beep generation and
enables normal operation of the CODEC.
Divider not equal to 00h - generates the beep tone on all Pin
Complexes that are currently configured as outputs.
The HD Audio spec states that:
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.
