like paul said. you didnt change the default device.

use:
mplayer -ao alsa:device=jack   
or 
mplayer -ao alsa:device=jack=mplayer

this wraps a plug device in another plug device.
i actually dont know how smart this is ;)

i have 
pcm.!default jack:alsa-default


it will only work fine for the default. the jack plug it self, is not
very flexible, and many clients would complain that they dont do float
and fixed SR...
