Right Line-In Volume. Allows setting the Line-In Right channel attenuator in 32 volume levels with 31 steps of
Right CD Volume. Allows setting the CD right channel attenuator in 32 volume levels with 31 steps of 1.5 dB each.
Left CD Volume. Allows setting the CD left channel attenuator in 32 volume levels with 31 steps of 1.5 dB each.
Right AUX Volume. Allows setting the AUX right channel attenuator in 32 volume levels with 31 steps of 1.5 dB
Left PCM Out Volume. Allows setting the PCM left channel attenuator in 32 volume levels. The LSB represents
1.5 dB each. The LSB represents 1.5 dB, and the range is +12 dB to –34.d dB. The default value is 0 dB, mute enabled.
Right Channel Mute. Once enabled by the MSPLT bit in Register 76h, this bit mutes the right channel separately
from the LIM bit. Otherwise, this bit will always read “0” and will have no effect when set to “1.”
Left Line-In Volume. Allows setting the Line-In left channel attenuator in 32 volume levels with 31 steps of 1.5 dB each.
The LSB represents 1.5 dB, and the range is +12 dB to –34.5 dB. The default value is 0 dB, mute enabled.
Line-In Mute. When this bit is set to “1,” both the left and the right channels are muted, unless the MSPLT bit in
Register 76h is set to “1,” in which case this mute bit will only affect the left channel.
The LSB represents 1.5 dB, and the range is +12 dB to –34.5 dB. The default value is 0 dB, mute enabled.
Right Channel Mute. Once enabled by the MSPLT bit in Register 76h, this bit mutes the Right channel separately
from the CVM bit. Otherwise this bit will always read “0” and will have no effect when set to “1.”
The LSB represents 1.5 dB, and the range is +12 dB to –24.5 dB. The default value is 0 dB, mute enabled.
CD Volume Mute. When this bit is set to “1,” both the left and the right channels are muted, unless the MSPLT bit
in Register 76h is set to “1,” in which case this mute bit will affect only the left channel.

Right Channel Mute. Once enabled by the MSPLT bit in Register 76h, this bit mutes the right channel separately
from the AVM bit. Otherwise, this bit will always read “0” and will have no affect when set to “1.”
