Solved the problem. For some reason, audio and GPU do not work under the same bus (root.1). I upgraded my workstation to Fedora 24, which include newer libvirt version which allow the addition of ioh3420. So, I did add the video card to it, as explained in https://www.redhat.com/ archives/vfio-users/2016-January/msg00301.html. Again, if I add the R9 sound on the same bus, it gives me a BSOD. But now if I add the R9 audio to the pci.2 bus, it works; it no longer gives me a code 10. Probably some patch related to this code 10 was integrated into the newer version.
