i had an internal creative soundcard some 5 years back. sound was pretty perfect with dt990 pro and sz2000. my current creative usb soundcard has more noise :(
You’d have to put it all the way around it, including near the connector. Obviously you can’t put it inside the connector, but that’s another avenue for noise to get in. Outisde the box of noise with it’s own box of insulation is a much calmer place.
The inside of the PC is electrically hostile to good sound quality. Loads of electrical noise.
USB is an excellent use of a sound interface.

Get an audio interface such as a Focusrite Scarlett Solo. You won’t look back. The difference between this and a consumer sound card is night and day.
What if I put foil all around it
