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!
Regards,
Martin
