Comment (by CoRoNe):

 For future reference:

 [http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=57651493923ea4bc76453aa18fb0ecad7926720d
 5765149] introduced a sum option which was disabled by default.
 --> `amix=inputs=79:sum=1`.

 [https://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=95b854dd0630183d4130ad27097796ef167eb96b
 95b854d] (a week later) silently renames this option to (my suggested)
 "normalize" which is enabled by default.
 --> `amix=inputs=79:normalize=0`.
