 Summary of the bug: No audio when creating HLS from AVI

 How to reproduce:

 I'm using `ffmpeg version N-92215-g8baaed7889 built with gcc 7 (Ubuntu
 7.3.0-27ubuntu1~18.04)`
 The command I used is: `ffmpeg -i dev.avi -f hls out.m3u8`
 The input file can be found here: https://signalratio.ddns.net/fileserver
 /ffmpeg-files/dev.avi
 The output file can be found here: https://signalratio.ddns.net/fileserver
 /ffmpeg-files/out.m3u8
 Here is a log produced by "-report":
 https://signalratio.ddns.net/fileserver/ffmpeg-files/ffmpeg-master.log

 The output file appears to have some problem with its audio stream. When
 trying to play it using `ffplay out.m3u8` I hear no audio and in the logs
 I see:
 `[hls,applehttp @ 0x7f518c000b80] Could not find codec parameters for
 stream 1 (Audio: aac (LC) ([15][0][0][0] / 0x000F), 0 channels, fltp):
 unspecified sample rate`
 `Consider increasing the value for the 'analyzeduration' and 'probesize'
 options`

 Note:

 This does not happen using older versions of ffmpeg. I tried using the one
 packaged for ubuntu by default: `ffmpeg version 3.4.4-0ubuntu0.18.04.1
 built with gcc 7 (Ubuntu 7.3.0-16ubuntu3)`
 The command and input file are the same.
 The output file can be found here: https://signalratio.ddns.net/fileserver
 /ffmpeg-files/out3.m3u8
 Here is a log produced by "-report":
 https://signalratio.ddns.net/fileserver/ffmpeg-files/ffmpeg-ubuntu.log

 This file produced by the old ffmpeg plays fine with both the old and the
 new ffplay.

 This file produced by the new ffmpeg fails with both the old and the new
 ffplay.
