I am new to video editing and just captured my first dv with Pinnacle 10.5.4studio plus. The good news is the video capture went fine and all the editing worked great. The bad news is there is no sound--it is like Pinnaacle is not recognizing my sound card. I attempted to add music and still no sound. I see the symbolic wave form for both the audio track from the DV capture and the added music file from the Pinnacle library, yet no sound coming out the speakers.

Any suggestions? Am I missing something?
