We’ve now found out the underlying problem with silent audio export and fixed it for the next update.
Try the following workaround:
- Press the Rewind to Beginning button on the toolbar
- Press Space quickly twice. This starts playback but then stops it again before it outputs any events.
- Now do File → Export Audio
The reason for the bug is that the state wasn’t being initialised correctly when audio export starts, and so it is left at the state of wherever playback last stopped. So if you have played to the end of the score, the whole score is silent. If you played back part-way through, then you may have silence up to that point.
