There is a chance that you could fix it by:
A) Getting a powered USB hub, and connecting the DAC through that. (Be sure it's plugged into the wall, or it won't help much.)
B) Soldering a bypass capacitor to the power rails inside of the DAC, or
C) Getting a USB extension cable, and connect a bypass capacitor to it between the +5V line and Ground line. Connect the DAC to the computer through that cable.

B & C would not solve the problem completely, but would reduce the issue. The effectiveness of A depends on the quality of the USB hub.

That noise is from the switched mode power supply causing interference. One option is to get an external USB sound card. You can find them from $20 for a really cheap one to several hundred for an audiophile grade one. As far as real world performance, you won't notice a difference over about $60 in most cases. Another option is to use a USB headset, but those normally aren't very good. They can be worthwhile if you just need something to work, though.

That's a USB sound card or USB DAC. It connects to the computer via USB, and headsets via 3.5mm TRS or TRRS (standard headphone connection). Odds are that it's the problem. Try a different model.

The Sound Blaster E1 is a good option at a fairly reasonable price. There may be others that would work, as well.
