Bug Report 🐛
Context
Upgrading Remotion from 4.0.356 to 4.0.375 causes regressions in playback behaviour inside the RVE Pro player.
With 4.0.356, video playback, audio playback, and asset timing all function correctly. With 4.0.375, without changing any code, the playback becomes unstable:
- Video playback starts looping or “jumping back” unexpectedly
- Audio tracks do not play at all
- Adding audio still results in silence
The same project works perfectly on 356 and breaks immediately on 375.
A live working reference (4.0.356): Live Demo
A screen recording (4.0.375) is attached showing the looping and missing audio:
For context the video plays for a seocond, then loops back 0.5 seconds, then plays for a second then loops back again

This may relate to changes in how Remotion handles re-rendering, timing, frame advancing, asset loading, or internal audio hooks. But for context no code changes have been made inside RVE to trigger this issue.
Also for context, its worth mentioning that rendering the video seems to work fine. Only happens in playback.
