1 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
for examples.

Bit
Mnemonic
Function
ROV [4:0]
Right PCM-Out Volume
Allows setting the PCM right-channel attenuator in 32 volume levels. The LSB represents 1.5 dB, and
the range is +12 dB to 34.5 dB. The default value is 0 dB, mute enabled.
RM
Right-Channel Mute
Once enabled by the MSPLT bit in Register 0x76, this bit mutes the right channel separately from
the OM bit. Otherwise, this bit always reads 0 and has no effect when set to 1.
LOV [4:0]
Left PCM-Out Volume
Allows setting the PCM left-channel attenuator in 32 volume levels. The LSB represents 1.5 dB, and
the range is +12 dB to 34.5 dB. The default value is 0 dB, mute enabled.
OM
PCM-Out Volume 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.
