Download the latest version of Crystal CS4281 PCI Audio drivers according to your computer's operating system.

I have a Crystal CS4281 sound card and it can't work. I've just upgrade from Windows XP to Windows Vista. The sound driver 'Crystal SoundFusion(tm) CS4281 WDM Audio Driver' doesn't work in Windows Vista. And it says the following in the device manager. This device cannot find enough free resources that it can use. (Code 12) If you want to use this device, you will need to disable one of the other devices on this system.

The device instance does not exist in the hardware tree. I have visit the support at and been told that the old driver working with Windows XP is not capable of Windows Vista. Then I went searching in some driver download web site, but found no such driver that can runs on Vista. So could somebody give me a little bit help and tell me where I can find the driver? Also, if there's really no drivers for this device can you offer me a general sound driver that can solve this problem?
