Apologies for the unsolicited quiz, but you may have some answers to questions I've been wondering about recently:
Have you used it much for audio production? (perhaps with bitwig?) are there any noticeable issues with the latency or buffering? What sampling rate do you use it at? Do you have access to the optical I/O and everything? I'm assuming you don't get the focusrite control software (and therefore the remote control features)?
Full support has been patched into the kernel for a couple years now, and Focusrite seems to be pretty friendly to Linux compared to other manufacturers.
No noticeable lag or buffering that I've found. I've played around with a few DAWs, but I don't need them for my workflow, so I haven't spent a ton of time with them, and I'm no audio engineer.
The Focusrite control software doesn't work, but you can get remote control capabilities lots of other ways on Linux such as with remote Pulse Audio or Pipewire control, or simply using SSH.
