You mean that (or those types) of sound cards for recording specifically? The are great for gaming, but literally useless for recording . They are locked at 24bit 91,000khz, rendering them un usable. What kind of mic/power source are you using? A bad phantom power or pre amp will do it. Heck, a fluorescent light will do it. You could probably get rid of the noise in post, but always best to have a crystal base recording.
