I had this same problem with VIA on-board sound and have it with my
current nforce3 on-board sound.

This should not be too hard -- a config option to specify a maximum
setting in percentages and scaling the value in setPhysicalOutputGain()
should do the trick.

On the input side this is a bit more complicated, there should be
scaling factors for both Line and Mic as at least with my hardware the
usable IGain range is totally different for the inputs (0% <= Line <=33%
and full range for Mic).
