 Summary of the bug:

 I tried to add background song (in wma lossless audio format) to the mp4
 video and resulting video has corrupt audio.

 How to reproduce:

 ./ffmpeg -v 9 -loglevel 99 -report -i video.mp4 -filter_complex
 "amovie=wmal2.wma:loop=0,aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1[a1];[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0.3[a2];[a1][a2]amerge,pan=stereo|c0<c0+c2|c1<c1+c3[out]"
 -map 0:v -map "[out]" -c:v copy -c:a libfdk_aac -shortest output.mp4


 FFmpeg version built on : I checked out latest development version from
 git repository

 Command above works nicely with mp3 files and other wma files. I attached
 ffmpeg report log file.

 Regards, Aleksandar
