How to reproduce:
- Create a level sequence and animate anything, you may also add events.
- Add an audio clip
- Drag to multiple select the animation keys and the audioclip.
You can either have the audio clip selected, or the keys+events, but not both. Expected behavior would be to be able to select clips along with other keys to easily move them along the timeline in sync.
It’s worth mentioning that you CAN simultaneously select audio clips and other non-infinite strips in the sequencer. So if you deselect “is infinite” in a track and split the strips properly, you can move the audio clips around with your required animation. However this is not a good workaround because of many current practical limitations of this system (for example, there’s no way to re-merge a split strip and keep it non-infinite) and a cumbersome workflow.
