Hello! THX for your fast answer...
Yesterday I enabled VT-d in BIOS but it makes all of my mice and Keyboards unable to control anything even in OC boot menu... had to hard reset and disable it in Bios again to make keyboard etc work... Will try it again and report back.
Funny thing with the driver is, that Driver Software and MacOS says it is connected and loaded, so I can selct it in sound preferences and in Logic etc., also the kext seems to be loaded and active (as I've seen via terminal command) but I do not get Sound output.
Thank you!
I'm away from the studio for some days now. But when I come back I'll reset bios settings and start from scratch there.
In gpu, I have set primary-> automatic and iGPU-> enabled
I'll try to set primary to PCI-E. Maybe that's the problem.
I did this since with primary set to PCI-E I couldn't enter the bios, cause the screen was black.
Thx for helping!
I somehow got my Focusrite Saffire Pro 40 FireWire interface working on Monterey 12.5 today with very strange behavior!
Problem was: audio interface was recognized by macOS but audio output did not work...
audio output worked after the first startup with browser and Spotify. But, as soon as I started logic pro, audio output stopped working and was gone forever! All inputs including midi working.
Interface completely recognized by its software.
Today:
I did a clean install of Monterey macOS 12.5;
Reset the BIOS settings to optimal settings;
Set the BIOS according to post #1;
Set primary GPU to PCI-e; and
Enabled iGPU.
This resulted is FW interface is working again normally, with output. But all USB ports are broken; only pxsx controller working, no BT, etc.
After that, I went into BIOS again, set primary gpu to auto and iGPU to disabled.
-> same issue with the interface as before.
Again into BIOS.
Set primary GPU to PCI-e;
Set iGPU to enabled again; and
All is working normal now. USB, BT, fw interface.
Really strange behavior! But I am happy I solved it!
How is the FW audio output problem connected to iGPU?
I don't know.
