alsaplayer -o jack works reliably for me, I use it all the time.

I generally add the "-d transport/noconnect" option, then use qjackctl
(or the jamin Ports menu) to connect the output ports to jamin.  That
way you can start and stop (but not reposition) alsaplayer using JACK
transport commands.

Is alsaplayer able to play your file without JACK?  Can it play other
files through JACK?
