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

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 > > > -- > J Martin Rushton MBCS > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos
