Hello JohnM,
The Score huh? Well it is one of The Robert Cray Band's early works, ..., it does give you some of the powerful performances they would later become known for, you can pick up a copy here:

As far as getting audio for the RX 480 goes, hopefully it will be like what I am able to get with the RX 460. I am not using any connector information, or plug-ins at this point (I am trying to get some other things debugged and do not want to be confused with what the plug-ins would contribute).
Right now, I have a RX 460, macOS High Sierra Public Beta Four, Clover v 4128 -- just getting ready to update to v 4152, Inject-ATI set to false and nothing else as far as fake ID's etc. Everything graphics/audio is turned 'off' if that makes sense. But I do have the patch to put the controls into the Sound Preferences Pane. You can use Shiloh's tutorial and roll your own version or use Toleda's ready to go version:

(Make a backup of your EFI folder after you mount your EFI partition before running the script. Follow all of the prompts that get you to install the AMD audio.)
Note: Remove any Clover AMD audio patches etc. except for this one:
Code:
<key>Devices</key>
<dict>
<key>Audio</key>
<dict>
<key>Inject</key>
<string>1</string>
</dict>
Please note that any Clover patches for using motherboard not-HDMI audio will not apply, you can probably leave them alone. If you have Clover patches for motherboard HDMI audio, it might be a good idea to remove those.
What is important is the file you will download by choosing the Install Audio For AMD route in the script:
SSDT-HDMI-AMD-PEG0.aml
This one should end up in the EFI/CLOVER/ACPI/patched folder.
Restart and then look in the Sound Preferences Pane, you should have the listings for the ACTIVE and Connected DisplayPorts and HDMI ports -- they must be connected to a turned on monitor or a /v receiver before they appear in the pane. Choose one and then try iTunes or something like that and see what you get. You can also direct the system sounds to the DP /HDMI connections.
p.s. I have to take off at various times for various lengths of time, I apologize in advance if I am not able to respond quickly, maybe Gigamaxx will be able to help.
Note: right now, I am not able to get multiple monitors running on my RX 460, but audio is fine on the DisplayPort output as well as the HDMI output.
