Should the application add the dB range of Virtual Master and the dB range
of the slave for HDA-Intel ?

Correct me if I am wrong

PA server seem use  -168.00 dB to 0.00 dB. for hda-intel

For ad1988   spec->vmaster_nid = 0x04;

"Virtual Master" + "Front" + "PCM Softvol"  = 58.5 + 58.5 + 51 = 168

state.Intel {
    control.1 {
        iface MIXER
        name 'Front Playback Volume'
        value.0 39
        value.1 39
        comment {
            access 'read write'
            type INTEGER
            count 2
            range '0 - 39'
            dbmin -5850
            dbmax 0
            dbvalue.0 0
            dbvalue.1 0
        }
    }

The dB range of emu10k1 calculated by PA server is (-100081dB to +12 dB)

"AC97 Master" + "AC97 PCM" + "Front" = 46.5 + 46.5  + 99999.99 = 100093
