Tested on eros q, everything measured from line out,
open circuit.
- volume steps were approximately double the dB they
were labelled as, so "-2 dB" would result in a change
of about -4 dB from maximum (0, +6.2dBV)
- maximum volume defining the line out volume only
changed every 10 values, and then was not close
to correct- "-10 dB" resulted in -2.5 dB from maximum
This gets the volume dB approximately correct, and
maximum volume correctly sets the line out volume.
I was unable to get odd values in the max volume
to work, so set the step size to 2 instead of one.
For "consumer level" (-10dBV), set to -16.
For "Pro level" (+4dBu -> ~1.8dBV), set to -4.
