I think the general path you are looking for is that if you logically
want to raise a single band of EQ by 10db then what you really want to
do physically is cut the level of the other 9 bands by 10db leaving
the one you want at 0db cut. If you want to adjust the level of your
player at the end of the chain to get a final volume that's probably a
good feature to build in but in general I *think* that the final level
in mplayer should be viewed as a way of leveling different audio
sources as different audio files have a small/large degree of
variation in overall volume.
Hope this helps,

Keeping the audio at maximum values as far as
you can through the
audio chain is best for signal-to-noise, etc., and the audio at the
start of your pipe is doing that. EQing is now a subjective step you
are adding, presumably for good reason. To do this you cut the other
EQ bands so as to allow the band you want to be more promenent to come
through. You might just do this with a volume control at the front end
of your EQ unit, or you might adjust each of the unwanted bands. The
two options may have different sonic characteristics. Play with it and
hear for yourself.
Right. The question now is how do I control the overall volume? Is there
anything in the header which says how loud the track is? Not that that
will help here- I think my only option is to tell the mplayer at the end
of the pipe to turn it up a bit.
