I had a CMI-8330 sound card which has conked off. I had bought a new Creative VIBRA 128. The playback sounds fine, but when I try recording there is a scratching sound in the background. I tried many different settings as possible, tried changing the card to a different slot, etc... but it still gives me problems. There is nothing wrong with the mic (tested on another computer) and there is nothing wrong with the sound card either (had it replaced). Can anyone please help me out with this problem.
