 Summary of the bug:

 Ffmpeg 4.4.x play 24bit ape with big noise when using ffplay or compiled
 so.

 If simplely revert this commit it works
 fine:​https://patchwork.ffmpeg.org/project/ffmpeg/patch/20201006001714.19577-1-onemda@gmail.com/

 I have tried to dicuss with the author, he will not fix this problem
 because he want to do other things without coding.

 It also works fine in old versions like 4.3.x or other older version.

 How to reproduce:
 {{{
 % ffplay "24bit ape file"
 ffmpeg version built on 4.4.x
 }}}
