player's output circuit clipping at that output volume level.

Turn the CD player's output volume down until you see no clipping, then
turn your capture card's input volume up (if necessary) to achieve
maximum sensitivity for that level.

Clipping can occur in any amplifier circuit between the D/A conversion
(in the player) and the A/D conversion (in your input card).  If the
clipping is happening in the player's first analog stages after the D/A
conversion, before it gets to the volume control, you won't be able to
fix it.  Your only option would re-level the master WAV to within the CD
player's capabilities.  (I'd toss the CD player if that's true.)
