My Dell Vostro came with a RealTek sound card that does not work. (The volume for line in has no control) I am trying to transfer some cassettes and LPs onto my computer. I sort of accidently bought an M-Audio FastTrack on Ebay, but now that I look at the description, I don't think that is what I really needed. Can someone recommend a sound card or something, whatever it is I need to make a nice computer file out of my cassettes and LPs? Should I just turn around and sell the FastTrack thing? It doesn't come with any software anyway. Thanks for any help, I am very confused. I am using Windows XP.
