I have a floppy controller, but I stole the drive a while ago for my
Windows system which grew a requirement for one to support disaster
recovery. 

I have not tried the pcm0 in either case. I have no idea whether it
works right now. I'll be at the system at around noon (PDT) today and I
can try it. I have not use the sound card on that system in quite a
while. I seldom am physically close to it except when working on it.
