For AC ’97 compatibility, Bit D7 (RM) is available only by setting the MSPLT bit, Register 0x76. The MSPLT bit enables separate mute bits for the left and right channels.
If MSPLT is not set, the RM bit has no effect.
All registers are not shown, and bits containing an X are assumed to be reserved. Refer to Table 24 for examples.

Right-Channel Mute
Once enabled by the MSPLT bit in Register 0x76, this bit mutes the right channel separately from the
IM bit. Otherwise, this bit always reads 0 and has no affect when set to 1.

Input Mute
When this bit is set to 1, both the left and right channels are muted, unless the MSPLT bit in
Register 0x76 is set to 1, in which case this mute bit affects only the left channel.
Each LSB represents 1.5 dB, 0000 = 0 dB, and the gain range is 0 dB to 22.5 dB.
