@chiefsucker Thanks for the kind words buddy.
That is one very weird problem you have happening to you over there. Totally not normal and I’ve never seen or heard of anything like that happen before to anybody so I’m scratching my head somewhat trying to work out whats happened.
Il make a little list of things for you to try, most of them you have probably already tried but in case there’s something i say that you haven’t then give it a go and see if it helps.
In no particular order......
- Reset your nvram
- Reset your Bios
- Update your Bios to F33c (this is the most hard of a nvram reset you can do plus it’s worth it for agesa 1.2.0.0)
- Clear your cache and repair your permissions (your need to disable SIP in the config.plist before you do so)
- Remove your big Navi and put your 730 on the top slot making GPU0 then if it works move your big Navi under it
- Try changing from 29 to 1 and if that works then try 16 or 7
Other things are, If your using smbios 1,1 like I have it set then you 100% need the XHC-SSDT name changes. The gigabyte boards use XHC1 as standard and this conflicts with smbios 1,1 as it has a predefined map inside it using XHC1, this is bad and we don’t want this at all. You should be using my EFI as is but with your own personal USBMap.kext. I would do that again if I was you brother. I made that XHC SSDT specifically for the Aorus boards so it’s correct to use for your x570 master too.
Using a External DAC is never a bad thing, I use a Native Instruments Audio 6 myself but only for my DAWs or when I want to play back on my monitors, any other time I use the internal audio and it’s always worked a charm. Evan logic works flawlessly using the internal audio and I find that shocking as I even tried to stress it out and it totally just was having it...lol
Don’t get a DAC though if it’s only because your internal audio isn’t working as it should be so we must fix and get it working again for you.
On the extreme side have you tried a clean install? I know it’s a bit extreme but sometimes it’s the only way.
Time Machine back it all up and then wipe your drive and reinstall and then test and if all is well restore your time machine backup and it will be like nothing ever happened.
If I can think of anything else I will update this message.
P.S About your Big Navi, There is a general belief that support in Big Sur will be coming to those cards soon however I am not one of those people who holds that same hope as a lot of others. I don’t think it is ever going to get supported unless Apple release one more Intel Mac, Theres a rumour that there’s a Intel MacPro refresh coming out in Q3 of this year but from what I know and have been told it’s not true so if that’s the case then Apple will not just add support for big Navi and I don’t believe they care about the end user in such a way that they would give support for the GPU so poeple who bought the current MacPro can upgrade it. Apple don’t play like that I’m afraid.
I hope I’m wrong as nothing would make me happier then being able to slap a 6800 XT in my system but I don’t think I am.
