FWIW, I have been specifically looking at audio drivers for laptops on the Windows 10 preview. MS provide a generic driver. This seems to work with many of the chipsets I've tried. I don't know who wrote it, but it is being modified and updated regularly, apparently by MS. It doesn't expose the vital "Stereo Mix" or "What you hear" function where the hardware has not crippled this, but usually the manufacturer's drivers do. I have been attempting to raise this with the MS reps on the forum.
For external audio devices, many manufacturers provide Mac drivers in the same way as they provide Windows drivers.
Linux audio with external devices, on the other hand, seems to me to be a complete mess. Not only are the drivers difficult to find or non-existent, but the basic audio UI's are a masterpiece of confusion.
I'm with, I think it was, Bob H. What I would really like to find is a basic LTS version of Linux that has been developed by someone for simple useability rather than bells and whistles. Until I find that, I'm going to stick with XP, W7 or W10 for any real audio and hence most of my other work.
