I have Audacity 2.0.6 (.exe) and WIndows 7. I also have Behringer UFO202 A/D USB. This works normally as expected when connecting my PC to my amp (Marantz). For recording to Audacity to transfer some of my old cassettes from my NAD 613 deck, I have to set the record volume in Windows / Audacity very low. It’s at 0.04 in Audacity which is 4 in Recording Device / Advanced / Level.
It all works OK but I am concerned the level has to be set so low. Doesn’t seem right. The NAD deck Line Out is directly connected to the Behringer Line In and the Behringer USB connected to my PC USB as normal. (And yes, I have checked that the Behringer is set to Line and not Phono).
