jeez man, this is nonsense.
In PA we call the max hw amplification 0dB. And then we extend things both ways in software. And finally we mark the ALSA 0dB spot (i.e. the *hardware* 0dB spot) as "base volume".
There is nothing lost here.
And you get a cookie if you read this:

and this:

And then you'll notice that we actually thought about hw and sw volume ranges quite a bit and nothing is lost. For example, our recommended color-coded UI will mark the ALSA 0dB spot with a color transition from green to yellow, to give the user an idea that things get worse beyond that point, even if he doesn't understand dB or hw or sw volumes.
Please, just drop this thread now, and just read the wiki. Thanks.
