I work for MSFT and have been using an SPX as my primary device for a little over a year. I haven’t had an issue with user space applications, but I do have an audio interface that doesn’t work because the vendor (MOTU) doesn’t ship ARM64 drivers :(

It's sad. I'm using a USB-C to 4.5mm TRRS audio dongle, and if you can't get audio drivers, I fear my "exotic" setup is even less likely to be supported.

I've been wanting to try Windows 11 on ARM64 with a Microsoft or a Lenovo device, but nothing seems to have the basics I'm looking for like OLED for a laptop, or ECC (for both a laptop or a server)

If there were ARM64 options with ECC RAM, I'd buy that today and start deploying tomorrow.

The only ARM64 option with ECC that I know of is Ampere's rather expensive development workstation [0].

Does windows not provide a generic "class compliant" audio driver? I'm amazed it works so well everywhere else if Microsoft doesn't support it.

I went down this path. Yes, Windows includes an inbox USB audio class driver, but it lacks support for implicit feedback. The MOTU interface does not have a feedback endpoint, and relies on implicit feedback, so the inbox driver doesn't work. I think the inbox driver does work for Focusrite's interfaces - I guess they include the feedback endpoint, and both Linux and macOS support implicit feedback so MOTU's devices work there. Apple actually recommend implicit feedback only [0].

Thanks for the information! My Motu (M2) does live on a linux machine and it's been relatively painless, worked on MacOs as well, but required a driver download on Windows. I never dug into why. Audio interfaces tend to be finicky things on their own, I also have an Arturia Audio Fuse Studio that needs to be "rebooted" from time to time, no matter what OS its connected to.

MOTU 828mk3 supports firewire, if you want to try that approach.
