NCH Debut - No Sound on Preview in Debut Posted February 16, 2018 7 hours ago, Telephony said: By "preview" I am not referring to the list of recordings...what I do mean is ... I have the Hi8 camcorder attached and hit the play button on the camcorder. The video plays on the Debut screen, but no sound is there. I haven't yet hit the record button, but merely looking at the video (with sound only) before deciding what part(s) I wish to record. When I do hit the "record" button on Debut, both video and sound gets recorded.
