Linear compared to what ?
Do you mean quadratic ?

I haven't measured the volume controls of my soundcard, but I don't get 
the impression that they are linear. They use some kind of "percentage" of 
whatever unspecified.

If I dust off my [SoundMixer] external (for accessing the OSS-Mixer) I 
could make a loopback test that plots a graph and then do some kind of 
curve-fitting. (that external was written in Ruby ; I'd rewrite it in C++)

But if they make "mistakes" like that, it looks like they are caring about 
those users that are "confused" by decibels. You know, user-friendly for 
real users, those users that are more real than the other ones.
