Its really annoying and weir story. After i bought M4A785TD v EVO with integrated via hd audio sound card i have no sounds on my front left pannel. Iam using headphones, but ive connected my 5.1 speakers and only this channel doesnt work. I instaled all kinds of drivers, instaled another windows and still. So I decited to go and exchange the board for new one. Seller checked the problem and exchange motherboard on the place. After he do that we tested it and left front channel start to work. When i came back to home with my pc and connected my sennheiser headphones and left channel doesn't work! Checked on another speakers and the same result. Seller told me he tested motherboard he exchanged on their platform and it works perfectly o0. just don't understand. I reinstald all i could, changed operating system and still nothing. What's the problem?
