If you use mplayer with jack output (-ao jack) then it will 
*always* output in floating point format because that is the
only format that Jack accepts. And mplayer does not know which
soundcard Jack is using. Which means that

can't be true.

As said, Jack is *always* using floating point. It will convert
the playback channels to whatever the sound card can handle.
