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 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.
