Q: I am a 939Dual-VSTA user. At first, my onboard audio works fine with integrated audio driver under Vista™. After updating to Vista service pack 1, my onboard audio does not work anymore. Can you help me?(2008/9/5) A: Please update the C-Media audio driver 8.18.07_SPDIF to fix the problem. The audio driver is available at https://www.asrock.com/mb/download.asp?Model=ALiveDual-eSATA2&s=AM2
