I have a DELL Vostro 1000 with the 32bit version of Windows 7 RC (Build 7100) installed. I too ran into the problem of the missing recording devices. The onboard sound chipset is the Sigmatel chipset. I found my solution by hunting through the many Vista and Windows 7 forums. I downloaded the drivers from http://aic.lgservice.com/SWLDATA/KRSWL000/KRSWL000014/KRSWL000014302-b1-a1.zip Once installed the CD Audio and Stereo Mix devices were present in the list of recording devices.
