Instagram's silence when automatically playing videos is meant to avoid any rude surprises (especially for those around you), but that courtesy might extend too far for some. What if you're watching a friend's concert videos and would rather not tap on each one to hear the music? That shouldn't be a problem from now on. Instagram has confirmed to TechCrunch that it now autoplays the sound in all videos once you've enabled it on a clip. It'll reset when you leave the app, so you shouldn't come back to a noisy clip.
