If you’re able to play embedded YouTube videos on Safari on iOS but the sound isn’t working on the same site using Puffin, here’s the fix:
Tap on the three vertical dots in the top right.
Select Settings.
By default, the Ignore Mute Switch is turned off.
If you toggle Ignore Mute Switch, the sound should play fine.
The other way to handle this, of course, would be to actually switch the mute switch (on the side of the iPad/iPhone), but this is more to get the same behavior from Safari and Puffin—Safari, by default, seems to ignore the mute switch for embedded video.

Does not help on iPad Air 2
I wrote this blog post three years ago, so it may well have worked on an iPad Air 2, but both iOS and Puffin have been updated since then, so this may no longer apply to newer versions of those two.
