On Content rich pages, Syncing of seekbar and audio gets unsyncronized if we open the transcript layer(custom) in between. This issue majorly occurs on heavy content pages.
This ultimately results in audio finishing earlier than the seek bar progress.
If you take off the audio seekbar, and start the audio when the slide timeline starts, the audio will use the slide timeline. Then when you show the transcript layer and it stops the base timeline, the audio will stop, too. When you close the layer, the timeline will start and the audio will, too.
With only one timeline, there is nothing to get out of synchronization.
But, "Allow seeking" is already "No" and "Pause timeline of base layer" is "unchecked" for the transcript layer so basically there is only one timeline.
There is a lot of text on the transcript layer so when the user opens to transcript, there is a little bit of lag in loading the layer.
The seek-bar pauses due to this lag but the audio keeps on playing.
This result in unsynchronization of audio and seek-bar.
Audio finishes early than the seek-bar.
The more number of times you open-close the transcript layer, more is the delay in audio and seek-bar.
Try checking "Pause timeline of base layer", then create a trigger to "Resume timeline on slide when timeline starts on this layer". You may not like it, because it makes a noticeable break in the audio, but it will keep the timeline and the audio in snych.

Thanks for the suggestion, Walt.
