I have a very unusual problem related to the audio/sound of my system. I am running on Win 7 Ultimate x64. While I have Asus Mobo M4N68T-M LE V2. The problem is that when I start my system my audio works fine, but suddenly a pop-up message appears from the notification area "Jack plugged in"(VIA HD Audio Deck) and audio stops working. I dont get any sound from my speakers as well as from my headphones. I have checked everything from my Speakers to Headphones everything is working fine. But still I cant get any audio output from my system. Please help me out.
