Enable internal PC-Beep generation.
Divider == 00h disables internal PC
Beep generation and enables normal
operation of the codec. Divider != 00h
generates the beep tone on all Pin Com-
plexes that are currently configured as
outputs. The HD Audio spec states that
the beep tone frequency = (48kHz HD
Audio SYNC rate) / (4*Divider), produc-
ing tones from 47 Hz to 12 kHz (logarith-
mic scale). This part can selectively
generate tones with frequency = 48KHz
* (257 - Divider) / 1024, yielding a linear
range from 12kHz to 93.75Hz in steps of
46.875Hz. If the FreqShift bit is set, then
the beep tones generated have frequen-
cy = 48KHz * (513 - Divider) / 1024,
yielding a range of 24kHz to
12093.75Hz in steps of 46.875Hz.
