For certain, if you are running at near-gig levels on your PA at home and are not hearing all kinds of computer noises, then you are blessed with a really decent laptop with top-quality audio shielding. You would definitely hear it if it didn’t have that, and since crappy shielding is what we have normally experienced over the years it is great to hear things have improved.
The Realtek audio cards set milestones with audio quality and became the industry standard, so it is not true any longer that the audio chips are crap. The other manufacturers have had to follow suite. That coupled with the huge improvements in latency Microsoft introduced in Windows 10 for WASAPI have really closed the gap.
