Yep, after you've set up the source, right click on the card and you can find the source(s) you've set up for that input. One of the options for that input is sensitivity.

Default is 2.0v -- I would work down one setting at a time from there. What that does is set the voltage required for 0dB FS (ie a full scale signal input).
