iOS8 beta 2
Corona SDK 2014.2359
iPod Touch 5th gen.
I noticed that Corona audio will stop (audio.* API) after a Vungle video has been displayed.
The game audio remains silent during gameplay. When a new Vungle video is displayed, the video-audio is audible during video playback, however after the video is closed, the game audio still remains silent.
Suspend/resume brings game audio back.
