I'm having this issue as well, in version 3.55 (paid version). It was working fine all day yesterday, but now there is no volume when I try to play a track. All volume is up, tracks are enabled, etc. I'm also having an issue where I copy a portion of a track, but when I open a new project and paste the copied portion, it pastes an empty track (not the audio that I clearly copied).
