    <p>Thanks for checking.<br>
    </p>
    <p>After adding nohz_full, rcu_nocbs, isolcpus parameters to my grub
      cmdline and switching to the Ubuntu lowlatency kernel it seems the
      sound is quite good when playing youtube video's or vlc. No
      crackles or noise anymore. <br>
      Not sure if there is really causation with using the lowlatency
      kernel, but when using the generic kernel I still had a lot of
      noise and some crackles.</p>

                                        <p>That would be interesting to
                                          see indeed. Actually I bought
                                          the RX460 because first I
                                          wanted to use my old HD7850,
                                          but then my pc didnt even want
                                          to boot (linux, didnt try
                                          windows). It just hanged
                                          seconds after grub loading
                                          with a lot of those PCIe Bus
                                          Error's. Then I tried a couple
                                          Nvidia NVS295's I had but I
                                          couldnt get them to work
                                          properly (driver issues which
                                          caused mismatching colours).</p>
                                        <p>Probably there is just
                                          something wrong with that MSI
                                          RX480, as it gave those PCI-E
                                          Bus Error's also when it was
                                          the only GPU in my system
                                          (while I was waiting for the
                                          RX460). But then again, it's
                                          strange that the rom could be
                                          extracted correctly with GPU-Z
                                          under Windows. <br>
                                        </p>
                                        <p>I did a Unique Heaven test
                                          and the results where not bad,
                                          ~1350 points and 53fps. But
                                          during some scenes it seemed
                                          the camera movement slowed
                                          down and then sped up
                                          significantly a couple of
                                          times. It didnt look like that
                                          was intentionaly but that said
                                          there was no drop in fps. Will
                                          do some more tests tomorrow as
                                          I am also not yet really happy
                                          with the sound quality (too
                                          much noise sometimes).<br>
                                        </p>
                                        Yes, I extracted the uefi bios
                                        from
                                        edk2.git-ovmf-x64-0-20170120.b<wbr>2426.gaa961de.noarch.rpm.

                                                Thanks, if I add the rom
                                                (the one I saved using
                                                GPU-Z under Windows) my
                                                display turns on.<br>
                                                <br>
                                                Unfortunately it didnt
                                                work then yet, as my
                                                dmesg was flooded with
                                                the following message:<br>
                                                vfio-pci 0000:01:00.0:
                                                BAR 0: can't reserve
                                                [mem
                                                0xc0000000-0xcfffffff
                                                64bit pref]<br>
                                                <br>
                                                This was caused due grub
                                                loading vesafb for the
                                                RX480 as the graphical
                                                terminal was enabled. So
                                                in /etc/default/grub I
                                                had to add
                                                GRUB_GFXPAYLOAD_LINUX="text"
                                                and disable
                                                'GRUB_GFXMODE' (not sure
                                                about the last one as
                                                maybe thats implicit but
                                                it doesnt hurt either).<br>
                                                <br>
                                                Unfortunately that does
                                                mean I cant use
                                                ddccontrol it seems, as
                                                that complains about
                                                missing a framebuffer
                                                driver. Therefore I've
                                                also asked Asus whether
                                                they plan to support
                                                choosing the primary vga
                                                slot like Gigabyte does
                                                and they said 'they will
                                                discuss this
                                                internally'.<br>
                                                My Asus support agent
                                                actually had never heard
                                                of vfio before and
                                                repeatedly said that
                                                Asus only supports
                                                multiple GPU's when
                                                using SLI/Crossfire. So
                                                maybe if more people
                                                would contact their
                                                local Asus support agent
                                                and request this feature
                                                they are more willing to
                                                look at it? Who takes
                                                the hint? ;)<br>
                                                <br>
                                                I had to install the
                                                driver twice as the
                                                first time the install
                                                failed, but at the
                                                moment the GPU appears
                                                to be working correctly.
                                                Now first on to sound
                                                before I do some 3D
                                                testing.<br>
