Comment (by DJRumpy):

 I'm not sure why the original poster had such an issue with posting a
 sample. The issue still exists. You can find a sample here. This sample
 will play without issue on an Apple TV.

 As long as the first audio stream is 2 channel AAC, any subsequent tracks
 can be passed via bitstream to an external tuner. This was tested and
 works without issue on a Gen 2 and Gen 3 Apple TV.

 I was able to work around it by forcing the output format (-f mp4), but I
 don't think this should be necessary.
