Small audio glitch

I am getting a small audio glitch on Apple TV 2 & 3 when playing back a stream with multiple audio bitrates only as alternate audio (not muxed in with the video) that is occuring just as the playback first switches between the audio streams.


Does anyone have a way to generate a known good reference stream with multiple audio tracks that works with Fairplay on Apple TV gen 2 and gen 3?
