What's terrible? It just work out of the box.

I use Ardour on Linux when I have to and what is terrible is that to get acceptable latency and jitter I have to use the sound system at the ALSA level. This kills sound for any other app I happen to be running. Pipewire introduces too much latency for recording good live performances and getting jackd to run properly with Ardour is something I haven't had success with yet, though to be fair I want to record music and not futz around with some baroque sound system. Half the time after quitting Ardour I have to restart pipewire/wireplumber et al to get sound working properly again.

In contrast, on MacOS I plug in my USB sound interface, it appears in my DAW and I'm on my way. And yes, I am getting a Mac now.
