Hello, just a new beginner starting off with a home studio. I downloaded Mixcraft to put on the PC and attached an AT4040 microphone via the Icicle XLR to USB converter, and tried recording some audio. Both the computer and Mixcraft recognize the Icicle. I can't hear anything from it, but it worked yesterday with the AT2020 USB mic. It seems to be a microphone or converter problem, because even using Sound Recorder detects almost no audio. EDIT: I think it might be a driver issue with the USB Multi-Channel Audio Device.
