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.
