Audio icon in compound clip
When I try to create an audio compound clip, some segments are left out.
Typically these have an audio icon (example attached).
If I double click in this segment, it splits into two parts. If I click
again, the split disappears and so does the audio icon, and I can proceed
to create the compound clip. This does not always work and, often, the system crashes.
What does the audio icon mean? What am I doing when I double click and split the clip twice?
Thanks
