AppleALC patch no ALC1220 sound when Thunderbolt audio interface connected

[sonofchocula]

Like the title says, the AppleALC + Lilu patch for ALC1220 works fine on my Aorus Gaming 7 system EXCEPT there is no sound via ALC1220 when I have my Universal Audio Apollo Twin connected via Thunderbolt to the Titan Ridge Thunderbolt card.

IORegistryExplorer shows everything being setup correctly (proper layout id etc. for the ALC1220 and proper PCI configuration for the Apollo connected via TB). I have included screenshots of the IOReg results with this post in case anybody spots something I may have missed.

Has anybody else run into this? Any ideas?

LMK if you want my EFI setup, though you'd have to tweak it for the GTX. I had to revert to F7, Ultra Gaming 7 users had to revert to F10. I'm using the Apollo 8 with Apple TB3 to TB2 dongles and cables.

Just seeing your comment, I'd love a copy of your EFI if you don't mind.

Okay. I cut out the Themes folder and the Apple folder. Note that I've never used onboard audio on this build. Everything goes through the UAD Apollo 8.

Just so you know, Thunderbolt hotswap was working, but now isn't after the last OS update. Rolling back to 10.14.2 yielded no better result. Now I'm wondering if there was a firmware update in the last OS update that has bricked the ability of Alpine Ridge to hotswap. You'll still need to power up the Apollo and wait for it to settle before turning on the PC.

Maybe you can fix it. IDK. Sometimes, I have to restart the PC to get the Apollo to connect: The "host" lamp turning on, "Connecting to Apollo 8" dialog, etc.

This config is specifically for my build sig. Read that link. I put in shortcuts. After you do all that stuff, make sure that the Apollo is set for sound i/o in System settings. If you're using Pro Tools, it'll sometimes try to change the playback engine to Pro Tools Aggregate Device, so make sure it's behaving.

PS: You'll need to click some things... I put in a new serial for you, but YMMV...

Super appreciate this! I know the drill with referencing other people’s EFI folders. If I get anywhere, I’ll be sure to share with you as well.

As an aside, I’m thinking my onboard audio issue has to do with an HDMI audio conflict (despite my displays not having built in sound). The Realtek and Intel devices are sharing the same layout ID no matter how I approach it and I’m not sure if or how I can disable HDMI audio from being recognized.
