I have a mwave modem/soundcard that came with an acer 233MGHz PC. I am trying to use the line in input instaed of the mic input, to make recordings from for example a datplayer. I do have audio recording programs but I can't figure out how to switch the recording mode from the mic input to the line in input. I can hear music through the speakers of my PC when I have a datplayer connected to the line in input, but none of the programs will record anything. What is it that I have to cofigure???
