Thanks for the response Bob. This is a case of all the clips coming from the same camera. Same AVCHD compression codec. One day you could load a clip into the source window, set in and out points and hit the insert or overlay icon and linked audio and video would go to the timeline. The next day and ever since only video goes to the timeline. To me it seems like a software switch has flipped somewhere. I can drag the clip to the timeline and it comes with video and audio. However, if you click on the insert or overlay icons only video comes to the timeline. It’s like dragging the video only icon to te timeline.
