cwawdm.sys is not a model, it's a file name.

Please describe your hardware so we will have something to work with.

eg: brand and model of pc it came pre-installed in?
or
brand and model of retail motherboard it came integrated in

and last, say whether it's integrated on a motheboard or a PCI add on device.

That's same of my problem...

My Laptop Dell C400, use Soundcard Crystal, but when i'm done installed the driver, it says like that the file needen cwawdm.sys

How repair it.....Please.....:hail:

cwawdm.sys is present in all previous versions but missing in A09, and due to this the user is prompted for the path to the file.
Just pick any version prior to A09, download, check to see if the required file is present.
