Timeline preview does not reflect trimming of sound effects
When a sound effect is placed in a timeline, and then you trim the end of the sound effect, that trimming is reflected when you scrub the play head, but if you press the Play button in the Timeline Preview controls at the bottom of the timeline, the full sound effect plays as if it was not trimmed.
To reproduce, simply follow the Cinematic Sound Design tutorial. You can reproduce it at the end of step 2 of this tutorial.

The issue you have reported I can confirmed has been bugged
Thanks Lara L
I have the same issue, and not only in the timeline preview, but in Play Mode also.
