When recording narration to go along with my slides, no matter how long the actual narration is, the timing sets itself to just under 30 seconds. When viewing the slides in the Slide Sorter view, the actual correct timing length displays, for example 47 seconds. But when viewing the slide's narration length in Normal view, it is set at 29.67 seconds, and will not go higher. When listening back to the recording, sure enough, it cuts off at 29+ seconds. I have checked and unchecked all of the timing options under Slide Show and Transitions both, including set the Advance time to the higher time. But although it will allow me to record for as long as I want, it will not play back more than 29.67 seconds. What am I missing? I am definitely not an advanced user, but this is not my first PPT presentation and I've never had this problem before.
