There are two panels, one Audio Backend then below it MIDI backend.
I think perhaps you looked under the Input Device of the Audio Backend.
But this already shows a difference from what I see - you have no
PortAudio option (which I have) and you *do* have ALSA and JACK options
which I don't have.
I don't know too much about it, but my guess is that this isn't the
plain vanilla build but one with JACK and ALSA enabled and PortAudio
disabled. IIRC it is Edgar Aichinger who builds for Fedora.
You could try the binary - this you can install without root permissions
 http://denemo.org/downloads/denemo-1.1.0-0.linux-x86

I'm not able to run this myself, but I believe it works fine on other
distros.
