I also had to add a load more custom types that are in the latest Intents file now which aren't covered in the guide.

What guide? The guide on github should be current, but if you've noticed something that's missing, please let us know.

Lastly, I notice that when you create an Alexa Skill you can choose whether your skill will use audio controls.
This would be great to add to the intents file if it's possible. e.g. "Alexa pause" would hopefully pass that through to the correct skill.

This is on my list of things to look at.
