Sound driver: Overall gain?

[Joe]

Weird title, I know.

Okay, to the point: My laptop speakers are decent, but Windows doesn't want to push them enough. In Foobar2000 I found an option to apply an overall +12dB to it's output and this was enough to hear my laptop in the car (read: minivan on the interstate, I wasn't driving) with minimal (some) distortion, with no sign of the speakers getting upset.

Is there a way to do this to overall sound with stock sound drivers, or does anyone know of a place where I could obtain modded drivers with a +/-dB option? It doesn't bug me enough to make it a DIY project, but it'd be neat if anyone knows.

(It'd bug me if it's a driver hacked to a static +10dB or whatever, cause that'll cause it to be too loud at home at my desk.)

*Notes that you could simply use the volume control to turn it down then.... Duhhhh*

There's probably a convenient way to do this by writing an upper device filter in the kernel.  One might already exist in fact.  But I don't have any more specifics.
