Inserting audio into slide
I created a teaching lecture with 140 slides. Many of them have voice narration and work well.
However, for one slide I cannot insert a (short) audio file. The format for all is .mp3 and worked well for all of the slides except for this one. I also had my narrator re-record the file and it just would not work. When it is embedded into the file no audio is inserted (with the old and re-recorded files).
I also tried to insert these two audio files into a new presentation and it just won't work.
Any idea why this may be happening?
