Hmmm, at this point I would start thinking about posting your problem to
the alsa-devel list, it might be a known problem with your particular
hardware. What is your card kernel driver? You could also do
a /usr/sbin/modinfo snd-xxx where xxx is your card driver to see if
there are any "interesting" load time options. Some hardware can't be
completely auto-detected and needs you to tell the kernel what you have
exactly (just an idea). 

Does the card have more than one midi i/o port?

Does it work on a regular non-rt kernel?

I think so, but it all depends on the hardware you have.
