Fixes require a bug. The only bug here is in your brain.

No, it is not. 0 dB is the value where no on-card amplification takes place. 
  If that seems to turn out louder from one card to the next even with the 
same equipment behind that line-out then that's unfortunate and we could fix 
it per-card defaults. What we definitely cannot do is redefine 0 dB to mean 
something else as you were suggesting for my cs4236 because you can be damn 
sure _I_ want to know the value where no onboard amplification or 
attenuation takes place. I control volume on the external amp hooked up to 
the card.
