My wife does pro audio work as well. We both got fed up of the pure trash quality of MS’s updates (offline is not an option as remote sessions are sometimes needed). It got so bad that she had to comp a full session due to driver issues. So, despite loathing Apple, we bit the bullet and got a MacMini from Costco. Not quite Linux but it is unix- like and extremely stable.

For Linux, maybe check out Ardour, if you haven’t yet.
