Full disclosure: I'm a middleware guy, and I greatly prefer to run linux as a server operating system. I have 25+ years of experience as an IT administrator and am more than a power user on linux. Off the clock, I make music and have used PC and Apple based DAWs for 20+ years, starting with a Pentium 75 with a Turtle Beach soundcard back in 1994. Today, my wife is a pro voice actor (if you listen to Pandora, you've likely heard her) and we maintain a professional level recording studio in our home. Said studio runs Windows 10 and Cubase 8.5 for a DAW.
That said: There are better platforms upon which to do digital audio. If you're doing this with any intention of making money, spend money on your operating system. Linux struggles to be a decent desktop OS as it is; there's no need to introduce driver issues and under-supported DAW software into the mix, while at the same time dealing with a dicey desktop OS.
Windows and OSX are by no means perfect - but they're supported solutions that DAW software and interface drivers are specifically coded for. Open source is fantastic in the enterprise, but I would never, ever risk my wife's career on community supported software. As it stands, running Windows is dicey enough - and we'll be moving (back) to OSX once I work out a monitor/keyboard/mouse sharing solution that doesn't cost an arm and a leg.
