Hi, I installed a new pc based on Intel DG33FB Mobo / Realtek ALC888. I connected 2.1 Speakers to the Rear Panel on the Mobo and it was working fine. Suddenly from the past 5 days, the Speakers do not work. The Speakers are fine as I tested them with the Front Panel Output as well as the Line In and Microphone Jacks in 6 Ch Setup. Another Problem is that the Front Panel Audio is not disabled even if I select to disable the Front Panel Support from the Realtek Manager. I have the latest drivers - re-installed twice. I tried System Restore - No Help. I tested the other jacks Line Out / Microphone In with the same speakers - they work properly. The Front Panel Jack is also working properly. But the Rear Line OUt Jack just does not seem to work. Anybody can help ???
