How do I make the sentence mode play the audio from the audio file?

I added an audio file and a transcript with timestamps.

I though that would make the sentence mode use the new audio file, but it is not, nor is it using the original video (which is the same voice as the audio file).
It is using, I guess, some synthetic audio?

Is there a way to have the sentence mode use the same audio file as the page view?

@zorbital We will look into this.

Should I just create a brand new audio-only version of the lesson–I think that would work as a work-around?

@zorbital Yes, you can do that as a workaround, and generate the transcript from the audio in a lesson.
