The Mixer couples analog input from 4 sources (DAC, Line In, Mic 1, Mic 2) each input has its own gain & mute controls.
At the moment only DAC is implemented fully and Line In path can be switched on/off. The patch implements Mic 1 and Mic 2 paths and fully implements Line In path.
Manual states that these controls (16.6.3.3 Programmable attenuation: GOi) gain varies from -22.5dB to +6.0dB with 1.5dB step. Also there's extra values below the minimum, but they behave the same as the minimum value.
