0 = no mute
1 = mute
The channels to be affected are determined by the SPLITMUTE bit
(Reg 72, Page 0, Bit D6)
If SPLITMUTE = 0 - both Left and Right channels are muted
If SPLITMUTE = 1 - only the Left Channel is muted
If a 1 is written to this bit, then ML<4:0> is loaded with 11111b. This bit
always reads 0.

00h = 00000b =
01h = 00001b = -1.5 dB attenuation
.....
1Fh = 11111b = -46.5 dB attenuation
Mutes Right Channel independent of Left Channel
0 = unmute
1 = muted
The SPLITMUTE bit (Reg 72 (Page 0), D6) must be set to 1 in order for the
RMute bit to have an effect on the sound.
The RMute bit is R/W and may be written and read regardless of the state
of the SPLITMUTE bit.
If a 1 is written to this bit, then MR<4:0> is loaded with 11111b. This bit
always reads 0.
