Comment (by Igor_Selivanov):

 Loewe TV doesn't have any problem with AAC audio and DVB-T2. Loewe TV is
 certified for DVB-T2 standard and uses Hardware interface for decoding
 (not FFmpeg). This problem is related only for FFmpeg. The attached
 example works even fine with '''VLC''', but not with FFmpeg.

 I did all test on my Linux desktop. Arch Linux has pretty latest version
 of software, in my case 3.3.2, but I can test it with latest from git.

 This error is related to certain transport streams. Basically FFmpeg can
 playback most (but not 100%) of DVB-T2 channels including ARD, but some
 programs are failed, because of AAC audio track. If you'd like I can post
 other examples.

 The reason why I post this issue is:
 "If you want to help, upload a sample of this file to .... " and I am
 developer too and, yes, I would like to help. I think for every developer
 is important to know limitation of own software, especial if we are
 talking about industry standard like DVB-T2.
