If you use "alsamixer", dB values are shown so it is easy to find the 0dB "sweet spot". I think it is pulse audio that hides this information when it combines two alsa mixer controls into one pulseaudio control.
The base volume seem to be the software 0dB point , (no software gain/atten), but the user want the hardware 0dB point (no hardware gain/atten if the hardware can provide hardware gain
This hardware 0dB point is extremely important when you want to record using line in and line out
alsamixer gives the hardware 0dB point.
