0 = no mute
1 = mute MONO output
If a 1 is written to this bit, then MM<4:0> is loaded with 11111b. This bit
always reads 0.
Mono Volume Control
00h = 00000b =
01h = 00001b = -1.5 dB attenuation
.....
1Fh = 11111b = -46.5 dB attenuation
0 = no mute
1 = mute pc beep signal
Bit not used, should read back 0
PC BEEP Frequency Divide
The Beep frequency is the result of dividing the 48KHz clock by 4
times the number specified in F[7:0] allowing tones from 47Hz to
12KHz.
A value of 00h in bits F[7:0] disables internal PC BEEP generation and
enables external PC BEEP input if available.
Bit not used, should read back 0
