^^ Check video, that is a blank project with only a single looping audio file playing on iphone 6. It still throws up Buffer Under run errors. I do NOT get buffer underrun errors if the audio is triggered to play but volume is set to zero. I DO get buffer errors if the volume is .01 or greater. Adjusting buffer settings does not appear to have any effect on the frequency of the error. It is consistent and should be easy to re-produce.
