I've bought this model about 9 months ago, and since then I've been using a USB headphone, even then the audio was off but I though nothing of it and assumed it was a headphone's problem.
Just yesterday I bought a new headset that uses the analog jack, and I've been experiencing a noise that starts when an audio plays and and stops 4-7 seconds after, long story short I searched and found couple of threads here that describe the same problem and some solution( which I tried) and nothing seems to so the trick, the only difference I've noticed is that when switching to windows drivers instead realtek is that the noise never stops now!!!
Please advice.
