ADC3 ADC2
Mute[D15] Mute. Mutes the input of Extended Audio DAC1.
Mute[D7] Mute. Mutes the output of Extended Audio ADC1.
DAC[3:0] Extended Audio DAC1 attenuation. Least significant bit represents 1.5 dB with 00000 = 0 dB. The total
range is 0 dB to -22.5 dB.
ADC[3:2] Extended Audio ADC1 gain. Least significant bit represents 6 dB with 00 = 0 dB. The total range is 0 dB
to +18 dB.
Default 8080h indicating mute with 0 dB attenuation or gain.
When EAM of the AC Mode Control (Index 5Eh) is set, the Extended Audio DAC1 attenuation is
controlled by ML[4:0] of the Alternate Volume (Index 04h) register.

DAC[3:0] Extended Audio DAC2 attenuation. Least significant bit represents 1.5 dB with 00000 = 0 dB. The total
range is 0 dB to -22 dB.
ADC[3:2] Extended Audio ADC2 gain. Least significant bit represents 6 dB with 00 = 0 dB. The total range is 0 dB
to +18 dB.
Default 8080h indicating mute with 0 dB attenuation or gain.
When EAM of the AC Mode Control (Index 5Eh) is set, the Extended Audio DAC2 attenuation is
controlled by MR[4:0] of the Alternate Volume (Index 04h) register.
