There are vista 64 bit drivers on the dell downloads here and they should work for win 7 64 bit.. there are no soundblaster audigy mb software on the dell downloads as this is an optional at extra cost item that also requires a product key to activate.. My dell xps m1330 laptop uses an audio device referred to as the sigma tel high definition audio codec. unfortunately after installing a fresh copy of windows 7 64 bit no audio could be heard, even though the volume was up at full and all the device drivers reported did not any problems.. There two chipset drivers listed on the downloads page for vista 32 bit and they should work on win 7 32 bit (regardless of version). there is also a sigmatel driver on the downloads. download and install the two chipset drivers and then the sigma tel and see if that corrects the problem..
