Yeah, Linux audio is great when it does work, but a real pain when it doesn’t. Looks like there is some work being done to bridge the DAW gap like https://github.com/microfortnight/yabridge-bottles-wineloader, but I image getting it working will be a bit of a rabbit hole.

Have you looked into using Wine or Proton to install Cubase on CachyOS? I see the wine page for it has a few garbage rating for the app, but I imagine that some of the work being done to get the steam games working might carry over to other desktop apps that didn’t work well on Wine in the past.
