Thanks Don for your help. I still need someone to give me a model number for a USB Sound Card that will work as I only want to do this once. I have been on the internet but none of the sound cards tell me if the mic input is stereo. The Creative X-Fi was too generic for me to tell which model to buy so if I had the rest of the model information that still might be the answer.
73 and thanks for any information.
