I have Windows 8.1 and have been recording vinyl via a Beheinger ufo 202. I noticed that my recordings were coming out in mono. Following advice on this forum, I changed the Windows setting to sterio mix and disabled the microphone. Since making this change, nothing happens when I click the Audacity record tab when playing an LP. Previously it would record. One thing I have noticed is that the Line In icon displays disconnected. I think this might be the cause of the problem, but I do not know how to correct the situation. The Beheinger is connect to the same USB port, as previously when I was making mono recordings with no problems.
