MIDI On A VM

I have an application (Frescobaldi/Lilypond) that generates and plays MIDI files. Due to problems with flatpak I can only run it on C8 or Fedora, both of which live on VMs. The host is running C7. I’ve tried
“adding hardware”, specifically a virtual sound card, to the VMs, but still they remain silent. How do I connect the virtual sound cards to the physical sound card so that I can hear the music?

Thanks, Martin

  • Hallo, witch virtualizer are you using. Sure that the virtual sound-device is connected with the right hardware?

  • KVM/QEMU

    I can play CDs and listen to YouTube on the host, so I’m assuming the hardware is fine.

  • 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
