I can't get an input signal when I try to record in 'WaveLab Lite', but I hear audio. I have a 'dell dimension 4600 with a pentium IV processor at 2Gigahertz, 1 gigabyte of RAM, Windows XP Home edition, and an E-MU 0404 Sound Card'. I went to the 'preferences tab' and chose the E-MU sound card, but I still get no signal.
