I did a search, and seems it was an 8.0.30 issue also.
It seems like some people have had the issue, but I imagine most do not (since its not widely reported) - so does that mean its not happening EVERY time volume automation is used? Can anyone confirm that they are NOT having this issue?
Edit : I did a quick test. New Project - one Instrument track (U-He Diva) - added some notes, plays back fine. As soon as I added a node in Volume automation track it cut out.
