Gain set to minimum but sound still too loud

I am running Windows 7 on an HP Pavilion Elite HPE. I have connected an ION TAPE2PC deck and am attempting to drive it with Audacity 2.0.3. I have turned the gain on the deck to its minimum setting but ALL of the tapes I am trying to transfer are coming across too loud - there is a huge amount of clipping and the sound is badly distorted due to overload. Is there anything I can do to address the problem?

Make sure that the [u]Microphone Boost[/u] is off (0dB). We know it’s not a micropone, but Windows might think it’s a USB mic.

Thanks for the suggestion of the microphone boost setting but the problemwas solved by using the Input Volume slider. This is probably obvious to experienced users - but, as you can tell, I’m a novice.

Thanks again for taking the trouble to respond.
