Stereo Input Mute. Setting this bit mutes the respective input signal, both right and left inputs.
Left Volume Control. The GL[4:0] bits are used to control the gain level of the left analog input
source to the Input Mixer. Each step corresponds to 1.5 dB gain adjustment, with
01000 = 0 dB. The total range is +12 dB to -34.5 dB gain. See Table 4 for further details.
Right Volume Control. The GR[4:0] bits are used to control the gain level of the right analog
input source to the Input Mixer. Each step corresponds to 1.5 dB gain adjustment, with
01000 = 0 dB. The total range is +12 dB to -34.5 dB gain. See Table 4 for further details.
8808h. This value corresponds to 0 dB gain and Mute ‘set’.
