Hi all,

I’m having issues with my Cubase 11 pro/RME Babyface pro combo.
It all worked perfectly up until now, for a few years.
At this point, whenever I press “record”, I instantly get: “Recording error: Asio Driver is not running.”.

I’ve just moved houses (so rewired things a little bit) and installed a fractal FM3 (which I know can also be used as an audio device).

However, I’ve tried everything I could find in related posts: uninstalling the Fireface devices, updating drivers, disabling the FM3 (don’t know whether it’s linked, but it’s one of the few things that changed). Starting in safe mode also offered no solution.
Some months ago, I remember I had one issue requiring me to restart the driver everytime, but that turned out to be a “Use USB2 instead of 3” (or vice versa) issue, and that did solve it.

Device manager is recognizing everything. Studio setup seems perfect, also recognizing the fireface device as it always has.
What else could I be missing?
(For now, I’m trying everything with the FM3 turned off, just in case that’s the culprit!)

I can solve it by updating my buffer size through studio setup/control panel.
Strangely enough:

    Starting at 48 samples. Error.
    Going to 64. Error;
    Going to 512: everything works like a charm.
    Going back to 48 samples: no more error message, but nothing being recorded.
    If I then restart cubase, I need to start the above from scratch again.

Of course, I’d prefer not to do this song & dance every time.

Setup:
AMD Ryzen 7 5800X 8-Core Processor 3.80 GHz with 32G of RAM.

I could understand that a small buffer size leads to noise... But the error makes me think it's something else.
Any clues?
