For a desktop OS, I'd only recommend it for experienced users and those who are willing to hit lots of walls and keep going. You will have a harder time getting almost everything running. For sound, you may have a lot of headaches if you don't like parsing logs for errors, scouring man pages and tweaking config files many times before finding a mix of settings that works. At least that was my experience the second time I tried to use it as a desktop OS (the first time, I gave up before I got to sound). Maybe try PC-BSD, which is aimed at providing a user-friendly FreeBSD desktop experience. FreeBSD does not implement lots of features or aim to be the first to support new hardware.

I have used it as a desktop OS for a few years, and it was definitely a learning experience for me. It was a great one though, because the experience helped me land my first job right out of college in a shop that extensively uses FreeBSD.

But TBH, you should probably just use it for servers ;)
