Audio and controller input dropout after switching to another app and back

[VrtlBrown]

Describe the bug So the game is running nicely, but then someone calls you or you switch to safari, maybe to look at a walkthrough, and when you come back to iNDS the audio has cut out and wont resume until you force close the app and restart. A similar thing happens to your controller if you have one connected (I'm using a 8bitdo SN30). This happens about 50% of the time when switching between apps.

To Reproduce

1. Play game
2. Receive a call, browse on safari a bit
3. Switch back to iNDS, resume game
4. Notice no audio, controller has dropped out.

Expected behavior Audio and controller resume
