Preliminary Technical Data
LINE IN VOLUME (REGISTER 0x10)
This register controls the LINE_IN gain and mute to the analog mixer section. The volume register contains five bits, generating
32 volume steps of −1.5 dB each for a range of +12.0 dB to −34.5 dB. This does not control the record ADC gain (see Register 0x1C).

CD VOLUME (REGISTER 0x12)
This register controls the CD gain and mute to the analog mixer section. The volume register contains five bits, generating 32 volume
steps of −1.5 dB each for a range of +12.0 dB to −34.5 dB. This does not control the record ADC gain (see Register 0x1C).
Many operating systems will play CDs directly using the digital data from the CD tracks. This control will only affect CD audio playback
if it is enabled for analog and this input is connected to the CD player analog connection.
