Probably falling under the stupid question category, but how do a USB headset and a sound card interact with each other? The headset I have (http://www.newegg.com/Product/Produc...82E16826158075) says it has a built-in X-Fi chip. If I plug it in to a computer with a discrete sound card, does the sound card override the chip in the head phones or do the headphones ignore the sound card? I assume there might be a way in Windows to select which source you're wanting to use, but will a USB headset still push the sound if the sound card is selected as the source? I did some google searching, didn't come up with much, hoping someone with experience will be able to clue me in. Thanks.
