Hello everyone, I apologize if there is similar post here but I couldn't find solution for my problem. I'm using Line 6 pod hd 400 and I have problem with it. When I connect it via USB, I hear the sound but it's lagging and cracking. Also, when I open FL Studio, it's a same problem, and recording/playing anything in FL lagging, cracking, and there are also visual laggs. I have updated all drivers, all programs but nothing changes. Don't know what else to do...
