Investigate audio alignment/duration issue

[jbilcke-hf]

Context

It appears that we have an issue with audio playback, on the "wasteland" example audio continue for about 4 seconds, so after the cursor gets out of the timeline's expected duration

I think this is due to a difference between the endTimeInMs - startTimeInMs which is shorter than the actual assetDurationInMs

Solution

• crop the asset (cut the sound when we are out of bound)
• maybe show a visual indicator to explain this (in some editors we can see when content is cut vs a natural end)
