GUIDE How to Enable Thunderbolt 3 Hotplug on macOS

[goodguy]

This forum is available and opened for help Do you have any other Thunderbolt to test?

Are there any other measures besides taking screenshots of the BIOS, I can take to troubleshoot or even solve the problem, that my Audio Interface does not come back - after the PC comes back from Sleep?
Or is "taking screenshots" the only help you provide on the path to a solution of this problem?
Maybe there is something wrong in the config.plist settings, that I provided for you, or the other settings, that I uploaded here, following quite meticulously your "problem reporting" instructions in Post#1 of this thread.
Or maybe in my xxx_thunderbolt.aml, the PCI Path is wrong? Or the IO REG Explorer File shows some errors in the Thunderbolt PCI settngs?

Indeed. Everyone has their way of diagnosing an issue.

Can you provide your PR files again to check thoroughly?

The SSDT for Hotplug is fine. However, a very interesting thing i noticed is the SSDT does not has the other dependency which is SSDT-DTPG and your IOReg shows the Hotplug implementation. Unless added in the SSDT, SSDT-DTPG is required for a full hotplug implementation. Also, remove SSDT-EC and add SSDT-USBX.

Implement the above mentioned fixes and attach a new set of PR files.

Here's the PR files. Sleep issue is still the same. When I shut down the audio interface before sleep, It doesn't come back after sleep. When I leave it on, it "survives" the sleep.

A simple reason could be due to use of stock firmware. Excluding TB, does the system has a working Sleep/Wake function?

Sleep/wake works perfect. As I already wrote, it also works on the Thunderbolt Bus as long as the TB Device stays ON during sleep. When I switch TB Device OFF before or during sleep, it will not come back after sleepwhen switched on again.

it also works on the Thunderbolt Bus

When using the Stock firmware, TB Bus is not and cannot be activated.

If I was to buy a Gigabyte GC Titan Ridge PCI card and flash it, could I install that in the ASUS Proart Creator Mainboard? I am asking about the connections the flashed Card needs, since the Proart Creator does not have a Thunderbolt header.
So would putting the flashed Card into the PCI slot and connecting it to Power (and I think they also have a USB2 Connector) be sufficient for full functionality or do I need to connect it to a thunderbolt header?

It could possibly work, with the use of Jumpering the TB header, as described in the TB installation guide. We managed to get EVGA Motherboard working, with a complete TB Hotplug function, where the Motherboard has no TB support and lacks TB Header too

Yes, but you need to check all the slot's path addresses for proper utilization. Confirm such with us before you buy a Card. Also, not sure why you prefer that way when your Motherboard is already equipped with a Thunderbolt 3 chip, probably, JHL7540 which can be flashed to a custom firmware. Instead of buying a PCIe Card and flashing a custom card, I suggest you go this way.
