Using a Presonus Quantum Thunderbolt 2 Audio Interface...HELP

I'm still a bit unclear of whether or not it might work if the VT1720/24 was added to the AppleALC supported codecs, that after that VRS8 could be recognized? I've been staring at the https://github.com/acidanthera/AppleALC/wiki/Adding-codec-support for an hour trying to figure out if it's something I could do... they say it's easy. Doesn't seem like that at first glance... or second.

Though now that I'm thinking about it, what could that do. @luckyal doesn't have AppleALC in his setup if I have understood correctly and he has a working VRS8.
It's not an HDA device so AppleALC doesn't help.

That would mean installing xcode. I remember somewhere that installing xcode might break something in Hackintosh... was that true or can I safely install it. Or maybe it was that it might not work well in Hackintosh that I read.
Xcode has not problem on Hackintosh.

So whatever needs to be found, is found. Or did you go some other root to make audio working on your system?
Yes found. All he had to do was not disable dart by removing (dart=0) from the boot-args in the config.plist (and enable VT-d and not drop DMAR). But this caused a problem with his USB and doesn't work on all types of Hackintosh (not x299).

I see that Envy1724 and Envy24 are mentioned there in the beginning as failing to create memory mapping...
Good find. The VRS8 driver does mention the name of the chips it's trying to control in the names of the methods and the name of the registers of the chips in the error messages.

There you go. :) I now have a working VRS8 and it didn't seem to break anything. Though that remains to be seen. No USB problems, but I already had a custom USBMap.kext.

I'm so happy! Thank you @joevt !!! And thanks @luckyal

I somehow missed the not dropping DMAR step because it wasn't on @luckyal list. I'm sure it was in the discussion, but even though I've read this thread again and again, I somehow missed it. I actually had it on, because I read that having it might prevent some issues with Vt-d. In this case it caused an issue. :lol:

So
  1. Enable VT-d from BIOS (there's no VT-x setting in Gigabyte z390 BIOS to disable VT-x separately that I know of)
  2. Enable above 4G decoding from BIOS
  3. Remove dart=0 from Clover congig.plist (if you have it there)
  4. Don't drop DMAR table (again in the Clover config.plist)
No need to modify VRS8AudioDriver.kext.

I'm beyond elated!
 
Excellent, @MyTosh - now my fingers, toes and earlobes are crossed that someone can make the same leap with the PreSonus Quantum....

Maybe the "same leap" works with the PreSonus - did you try those instructions?

No one has posted the information for the PreSonus setup yet or found the log messages that point to an error. Maybe logging uses a special method, so maybe you need to ask them how to enable logging to discover what the problem is with the driver.
 
@Slaughter, please update your profile (account details) with your Motherboard, CPU and iGPU or Graphics Card(s).
If you have a prebuilt computer enter make and model instead of motherboard.

I'm getting ready to build a hack for a friend based on z390 so this is welcome news! I had a feeling you guys were missing a step.
 
@joevt I am only in research mode.... no hackintosh... so can't help unfortunately. Surely the OP has that info? "PreSonus" is in the title... Will have to scroll back... I might tag or quote them to get their attention...
 
@BreBo, I don't have a Hackintosh yet, so I am not here for help with my build. I am here to research before I build. Hence my profile has no Hackintosh machine details. I don't have one yet!
 
Ok so are any of the PreSonus users who started this thread back in 1957 even still here since it became a thread about Slate? If so - consider this a shoutout to you to try a few things which have been documented over the last page or so.... @chicago_mike, @jdlux, @CDT

Apologies for my errors. Will use the code you provided and re up some info tomorrow for you. Thanks again for your continued support on this...
