[vfio-users] Problems with R9 290 audio

[Carlos Eduardo P. Guidugli]

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.

Thanks
