When I hook my Klipsch Promedias up to my soundcard, sound comes out fine, but when I hook up my headphones, the sound is very quiet now matter how high I have the volume set to. I can play CDs and plug the headphones into the cdrom drive and get loud enough sound, but that only works for audio cds. I would like to be able to play games and mp3s and use the headphones with them plugged into my soundcard, but the volume is whisper quiet when I do that. Is there any way to amplify the sound or something to make it so it is louder? I have tried using the software amp in winamp and sonique and it gets louder, but also gets quite distorted. Any ideas?
