I have a brand new, out of the box, custom computer with a ASUS P5KC motherboard in it, with the internal sound card and its software, Realtek HD Audio Manager, i can play the testing sounds throught the built in speakers in my ACER Widescreen. But, say for instance, when i try to play a song on Zune or play World of Warcraft. I dont have any sound coming out of the speakers. The same it true when I plugged my MP3's headphones into the front jack. the drivers are all up to date, i checked the site. And when i go to the "Sounds, Speech, and Audio Devices" menu in the control panel, it says i have no audio device and the "Device Volume" Sound Playback" ect. menus are all greyed out, below i have links to screen shots of the error messages.
