My post above is a perfect example. "These aren't language barriers." That's what it should have said. But, since I did not adequately proof read (and you cannot edit later) there's a typo in there.
Good thing I'm not the author of news articles.
As far as the article itself goes, I've not had much issue with popping noises with music on my PC. Have had slight backyard hissing noise, which is usually due to low quality recordings, speakers, amp, speaker wire, etc. But that's usually only if you turn the sound up a bit.
And since I have a pretty darn old set of 5.1 Creative Labs speakers, I don't expect HD quality audio from my system.
