The playback on my audio does not sync with the video. At first the record was set to microphone only and it was garbled (I am recording on a Dell laptop), then I enabled speakers as well (I have no idea what MMDevice/Filter driver is - I'm 68 and not as technically savvy as most of you) and got the two-voice effect. So I disabled microphone and now I get audio okay, but it doesn't sync with the video. I am recording on fast speed - it was originally on the slower speed, and I thought changing it might help the audio quality, but now I can't remember how to get back to the window to change it back. Would this even be of value? Help?
