Is fixed in Ubuntu 17.10 with latest patches. I've upgraded my ubuntu desktop 17.10 machine and the apparmor file was indeed patched; I shut down my Windows VM, reloaded apparmor and restarted libvirtd, and it was able to pass through the USB audio device.
Aside: I use xfreerdp to connect to the machine and use the flag "/audio-mode:1" ; this causes the Windows VM to use local audio, and this is how I am able to use the Cisco Jabber VOIP application with the USB headset. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1552241 Title: libvirt-bin apparmor settings for usb host device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1552241/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
