I cannot be sure but your "DJ Soundcard" looks like an audio interface with a digital usb in and 2 channel/stereo TRS outs, probably meant for a dj mixer, but unless it is tied to a single software, traktor for example, it will work fine as a normal "soundcard" or as usually referd to, interface. Dont use internal sound cards if you have this as it will likely be the same quality unless you are trying to set up a surround sound setup or play back ultra high quality files(192 and up)
