Exported AAC does not work properly

How to reproduce:
% ffmpeg -i in.flac -acodec aac -b:a 384k out.aac ffmpeg version 4.0.1 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 8.1.1 (GCC) 20180531
If I open 'out.aac' from the beginning (0 seconds), everythings works fine and I can jump at any position with no problem.
But if the player try to start to reproduce it from the middle of the file (2 or 3 minutes) the player hangs and it do not reproduce the file.
I have tested this behavior with smplayer (with mpv) and also with kodi.
If the AAC file is embedded in an mkv with multiple audio tracks I can't switch from an audio track to another one, unless I move back to the start of the file.
Also, the exported file has a wrong channel layout,
if the original file was:
Channel positions: Front: L C R, Side: L R, LFE
the exported one is:
Channel positions: Front: L C R, Side: C, Back: L R
I don't know if this 2 problems are related but it's the only difference that i noticed.
With ffmpeg 3.4.2 everythings works fine, instead with ffmpeg 4.0.1 I have this issue.
