The easy way if computer has decent DAC in it, is to run a long analog phono rca y connector from headphone output to stereo analog input. I've gotten surprisingly good results this way using very basic but decent quality laptops as the source.
The USB approach may work fine as well, but there can be a lot of variability in sound quality either way depending on many things. USB also may not be as reliable overall in some cases, depending on computer state. Its a case by case thing which works best. Maybe try out both and see. Neither should cost very much to try.
