I thought I would post this in case others have the same problem, I have suffered with this for at least 6 months, and finally found the solution today! I also did not see it documented anywhere.
When I would play videos in stories on Instagram, I had no audio. I checked all the obvious stuff, no luck. I finally stumbled on this, which doesn't make sense to me:
In Safari/Preferences/Websites/Autoplay, I had Instagram set to Never auto play media. Now, doesn't that mean never AUTO play it? It doesn't mean "don't ever play audio, even when I click to play it"? Anyway, I changed the setting to "Allow All Auto Play", and audio works! If you remove the entry there, and at the bottom the default is set to "Never auto play", that won't play audio either.
Unless there is some other underlying setting that causes this, it's illogical but it solves the problem.
