You don't care (ld.so magic). What matters is:

/dev/snd/controlC0 is opened, does it point to the correct device?
You can grep for ioctl and see if it is done with file descriptor 3
before the failure, in which case you know amidi plays with that
device. Why does it fail... I don't know...
And why does amidi try all the other devices after that I don't know,
neither what /dev/aloadXX is...
Maybe you can have a look at alsa.conf too...

Great help, no? :-)
