Enable internal PC-Beep generation.
Divider = 00h - disables internal PC Beep generation and enables
normal operation of the CODEC.
When the Divider is not 00h - generates the beep tone on all Pin
Complexes that are currently configured as outputs.
The HD Audio spec states that the beep tone frequency:
F = (48 KHz HD Audio SYNC rate) / (4*Divider)
producing tones from 47 Hz to 12 KHz (logarithmic scale).
This part generates tones with frequency:
F = 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:
F = 48000 * (513 - Divider) / 1024
yielding a range of 24 KHz to 12093.75 Hz in steps of 46.875 Hz.
