I am using a Diamond VC500 video capture card, connected through a USB port. In other video capture software there is sound, but not when using Debut (no sound in the preview, none in the recording). I have tested several different programs and found the picture quality provided by Debut to be the best, problem being that there is no sound. My sound card is a Conexant AMC and, as I said, provides sound through other capture software. Any tips on how to get sound through Debut?
