I answered a very old question here: Best way to setup USB mic as system default on Raspbian Jessie
As I had just encountered (and solved) the problem myself, so I though I'd answer the question anyway.
A few hours after I answered it I got +3 reputation from it, but no one had up-voted or accepted my answer. Furthermore, about 10 minutes later I got +2 more reputation from that same question, and again no one had up-voted nor accepted the answer.
My question is: where is this reputation coming from?
