Hallo, witch virtualizer are you using.
KVM/QEMU
Sure that the virtual sound-device is connected with the right hardware?
I can play CDs and listen to YouTube on the host, so I'm assuming the hardware is fine.
I don't know how this works here but doesn't playing MIDI files mean you need a MIDI capable sound card which generates the sound? Maybe the virtual sound-device is only capable to play audio?

Very good point. I will investigate further. I had two models in my head:
1) The Frescobaldi playback module did the MIDI-> sound conversion. 2) The virtual card passed the signals on to the physical card.
Perhaps your third model is correct.

Extra information: I've run up YouTube with the virtual sound card set to ac97 and can play back a simple audio stream. Running the MIDI system has no effect. Furthermore the mixer shows a connection from Firefox, but doesn't show one from Frescobaldi.
I think you've hit the nail on the head. Well done. Now how to fix it!
