Enable internal PC-Beep generation. Divider == 00h disables internal PC Beep
generation and enables normal operation of the codec. Divider != 00h gener-
ates the beep tone on all Pin Complexes that are currently configured as out-
puts. The HD Audio spec states that the beep tone frequency = (48kHz HD
Audio SYNC rate) / (4*Divider), producing tones from 47 Hz to 12 kHz (logarith-
mic scale).
