Dell Movie Studio Plus - Video But no Sound

Make sure your audio out from the VCR goes into your sound card's IN device. Then also go into your sound properties and make sure the level is up for the Line IN. After doing that, try another record(download) and test the sound. If it still doesn't work, check Dell Movie Studio Plus' preferences see if anything about what input your using. I'm not familiar with this specific software, but related packages sometimes in preferences there are options to select different inputs. (in case you have more channels or multiple sound cards)

If you are using Windows as your OS, make sure you have the newest drivers for your dell, check for drivers here.
