SoundMAX Integrated Digital Audio
...
1. Download these drivers and extract them to a folder somewhere with WinZip.
2.Open Device Manager (Control Panel | System | Hardware | Device Manager) find the entry for the SoundMAX, and update its driver with the one in the \SMAXWDM\W2K_XP\ directory that you just extracted.
3.Restart your computer.
4.Open Control Panel | Audio Settings | SoundMAX | Properties. In the 'Other' tab uncheck the first entry and check the second for digital audio. If you have analog speakers, leave both unchecked.
5.If sound quality is not that great, try changing the Format settings in that last tab on the page. Try going up or down until it works out.... I have this card and was quick to replace it... Time to get a new sound card if you are still having issues :(
6.Vista will tell you that Windows Update has found newer drivers. Ignore it or you'll lose the sound!
