I am having the same issue. Exactly the same to the T. I am using an at2020 mic and line 6 pod farm and the mic was working just fine a day ago. It has never been dropped or had anything spilled on it and it stays on the boom arm or I put it away in its soft padded case. Yet all of a sudden I noticed that it was no longer receiving input in pod farm. It was literally working a day ago. I noticed this post is over a year old but I was wondering if you were able to resolve the issue or did you just a get a new mic?
