The aim of the dB values in the ALSA mixer is this.
For Playback: Set all the mixer controls to 0dB. Send a sample digital signal from the CPU to the sound card. The measured analog signal on the line-out should be the same for ALL sound cards.
The dB setting in a mixer refers to gain, not level. Expecting the same absolute level from pro and consumer sound cards at the same gain setting is a little ridiculous. If I set a control at 0dB I want just that: 0dB gain.
