0 = No mute
1 = Mute PC BEEP
Bit not used, should read back 0
The Beep frequency is the result of dividing the 48 KHz clock by 4 times
the value of the number specified in F[7:0], allowing tones from 47 Hz to
12 KHz.
A value of 00h in bits F[7:0] disables internal PC BEEP generation and
enables external PC BEEP input, if available.
