Crystal 3D Stereo Enhancement. SE[4:0] = 00110, indicating this feature is present.
18-bit ADC Resolution. The ID8 bit is ‘set’, indicating this feature is present.
20-bit DAC resolution. The ID7 bit is ‘set’, indicating this feature is present.
Headphone Output (Alt Line Out). The ID4 bit is ‘set’, indicating this feature is present.
1990h. The data in this register is read-only data.
Master Mute. Setting this bit mutes the LINE_OUT_L/R output signals.
Master Volume Left. These bits control the left master output volume. Each step corresponds
to 1.5 dB gain adjustment, with 00000 = 0 dB. The total range is 0 dB to -94.5 dB attenuation.
Master Volume Right. These bits control the right master output volume. Each step corresponds
to 1.5 dB gain adjustment, with 00000 = 0 dB. The total range is 0 dB to -94.5 dB attenuation.
8000h. This value corresponds to 0 dB attenuation and Mute ‘set’.
