Thank you for volunteering. I would like to conduct this test somewhat methodically. Are you okay with the following approach?
  • First we will enable Vt-d and connect the Antelope Audio device. We'll examine the results.
    • This will be our baseline.
  • Then we can update the BIOS and check results again.
To begin, let's do the following:
  • State the make and model of your Antelope Audio interface.
  • Enable Vt-d by doing the following:
    • BIOS --> Enable Vt-d
    • config.plist --> Uncheck DisableIoMapper
    • config.plist --> Boot Arguments --> Remove dart=0
  • Reboot the system.
    • Antelope Audio device can be connected and powered before boot, or you may hot plug it afterwards. Either way is okay.
  • When system is rebooted, please ensure that Antelope device is now connected and powered up.
  • Run IORegistryExplorer and grab the following screenshots (press CMD-Shift-5 to capture screenshots):
    • At the very top of the IOReg tree you will see AppleVTD. Capture screenshot and post. It should look something like this:

    • Then scroll down to RP05 section (do not use 'search') and post screenshot of the DSB1 or DSB4 section where the Antelope device appears. In the screenshot below we can see that my Apple Thunderbolt-to-Gigabit Ethernet adapter is on DSB1:

If you have any questions, please ask at any time.
Ok, I post my reply with my phone because I have no more ethernet/wifi with vtd enabled. Finally, my orion32+ works on z390 F9i original firmware, with vtd enabled.

Awesome! We see that IOAudioEngineUserClient is finally present. The next step will be to send you the new BIOS, but you don't have 75 posts, which means I cannot send it privately. I am hesitant to make it publicly available because it hasn't been broadly tested and additional changes could be made.

But I may have no choice but to post it here and then remove it as soon as you've download it.

It is currently 1:33pm Pacific Time. If you can tell me when you'll be viewing this thread, I can post the file at that time and remove it once you've grabbed it.

Thank You CaseySJ
Wonderful relay race!

After flashing the BIOS, please configure BIOS parameters again:
  • Start with F7 (Load Optimized Defaults)
  • Remember also to disable CFG-Lock from Boot section and to enable Vt-d
  • Also please uncheck the current Thunderbolt SSDT in ACPI section of config.plist and add/enable the new one attached.
Then perform a cold boot (shutdown computer, pull power cable or flip PSU power switch for 15 seconds). When system restarts:
  • Check if Ethernet and WiFi are okay
  • Check if Antelope interface is still okay
  • In IORegistryExplorer, click on NHI0 (under RP05) and post a screenshot

D'oh! I thought I need to set the number of threads inside of the CpuTSCSync kext, and in trying to find the value in PlistEditPro, I caused all kexts to now show as folders.
I tried rebuilding Launch Services, but I think the command is for Sierra, because it didn't take. Does anyone have a Terminal Command solution for this?
