Not so long ago widely used audio codecs (the actual ADC/DAC part in the PC) had big problems with idle tones at low signal levels (which were simply gated off at silence, otherwise you would have gotten constant, looping artifacts). I managed to reproduce over 100 % THD+N with my old Thinkpad X200, i.e. more, very clearly audible, noise and artifacts than signal.
This is a separate issue though from the usually high output noise floor and poor isolation from other components, e.g. many complaints about many makes and models where CPU/GPU or even disk activity will induce audible pulse noises in the heaphone outputs or speakers.
