Question: I have a motherboard with Realtek HD Audio Codec. When I use Windows® XP SP3 or upgrade to Windows® XP SP3, the onboard audio doesn't work. What could I try?(2008/11/27) Answer: Please try the Realtek latest audio driver.
The driver is available from this link: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false
