MPlayer uses the bio2jack library for playback via jack (and the more I
see of it the more unhappy I am about it - well, if I did really care).

That's the messing of the bio2jack library, it always adjusts the volume
(yes, even if it is 1 it multiplies all samples by 1.0 !!!

Because the bio2jack lib can only handle 8 and 16 audio (currently).
So the solution for your problems is either to fix bio2jack or getting
rid of it... Patches welcome (if you can do it nicer and with a lot less code than bio2jack).
