I am unable to get any sound from the PT800CE-A V1.0 MB with Audio Realtek ALC655 6-Channel audio CODEC & Compliant with AC'97 2.3 specification. The speakers I am using for testing work just fine on my Dell. I have only installed the updated drivers from the ecs site. I have the following driver: RealTek Codec Sound on board driver - Version A3.68 (5770) - Release Date 2004/12/22 installed. I have updated my BIOS on my board as well. I have verified that the audio BIOS setting is on. I do not have any system sounds coming through my speakers. My volume control is fine. The speakers are connected correctly. Under XP SP2, I have my sound device turned on & it is the default device. I do not have any conflicts in the Device Manager. Any suggestions?
