Comment:

 ͏    Does it reproduce?
 ͏    `ffmpeg -y -v debug -hide_banner -nostdin -nostats -f lavfi -i
 "anullsrc=mono:d=50" -f lavfi -i "testsrc2=r=60:d=0.15" -shortest
 "Out.mp4"`

 ͏    Verification helper:
 ͏    `ffprobe -hide_banner -threads 0 -show_entries
 "stream=time_base:format=size" -of "flat=h=0" "Out.mp4"`
 ͏    `ffprobe -v warning -hide_banner -threads 0 -show_entries "frame"
 -select_streams v:0 -of "xml" "Out.mp4" -o "Out.mp4.xml"`
 ͏    `ffprobe -v warning -hide_banner -threads 0 -show_entries "frame"
 -select_streams a:0 -of "xml" "Out.mp4" -o "Out.mp4.a.xml"`

 ͏    The input audio is likely equivalent as that generated by:
 ͏    `ffmpeg -y -v debug -hide_banner -nostdin -nostats -f lavfi -i
 "anullsrc=mono:d=50" "long.wav"`
 ͏    ; alike.

 ͏    Your [/raw-attachment/ticket/11668/silent_audio.mp4
 ͏"silent_audio.mp4"] had unusually long audio.

 ͏    Nevertheless I cannot seem to reproduce your problem.
 ͏    (haven't tested the exact Gyan build on Windows though)
