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
