why iec958 switch in analog path ?

as 99999.99 represent infinite dB , how can mindB equal to -20000dB

    control.5 {
        iface MIXER
        name 'Analog Front Playback Volume'
        value.0 207
        value.1 207
        comment {
            access 'read write'
            type INTEGER
            count 2
            range '0 - 255'
            dbmin -9999999
            dbmax 1200
            dbvalue.0 0
            dbvalue.1 0
        }
    }


control.38 {
        iface MIXER
        name 'Master Playback Volume'
        value 202
        comment {
            access 'read write'

            dbmax 0
            dbvalue.0 -1325
        }
    }
