[linux-audio-user] midi won't play although sound works

I am sure I am just missing something very elementary but I have turned up all
controls in kmixer and gone through all how-tos and searched in google.

What I really want is to be able to compose and play with something like
MusicEdit. But I don't get anywhere close. Even the simple command:

pmidi -p 16:0 derdurst.mid

plays silently for several minutes. Tell me I am an idiot but tell me what I
am overlooking.

Thank you.

I am running Suse Linux 10.2. Some revelant information:
