I have an omnibook xe3 laptop. It's 850mhz laptop on which I plan on using n-track to record. I was wondering what kind of sound card I could get. I think an internal one would be out of the question. I was thinking pcmcia or usb. I guess usb might be little to slow though. Any sugguestions! I don't need anything really fancy (sb live! quality is fine) and preferably something that has four channels out or a digital out so I can get surround sound for my dvd player. THE BUILT IN SOUND CARD IS NOT CUTTING IT Please help
