Hello! So I've had my HP Envy 3D 17 for a couple of years now, and was having this stuttering audio and lag from the get go. I followed a few steps provided on one of these forums to fix the issue once before and it worked wonderfully. Recently I had to reformat my harddrive, so now the problem is back! I attempted to follow the same steps from the last post but the links provided are no longer available!
Here's the link: http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio-e-g-Windows-8/Sound-Issue-Probook-4530s-Partial-Solution-Need-The-Rest/m-p/960973#M16514

I believe it's the wireless card, and I've updated it to the latest one, but I am still having the problem!
I would apprecaite any help!
Thanks!
