Audio is muting. It's still there in the timeline but not playing back when I hit play. No meters and no sound but the sound plays fine from the source/preview window.
It is happening every time I switch from the timeline/edit window to the preview source window and then back to the edit window.
The only way to get the audio back is to switch to another project, or restart the software.
