As Carl said, please provide the complete, uncut console output of
your command (ffmpeg.exe -i "Dolphins_720.wmv" -ar 44100

Also, I'd be interested in seeing the complete, uncut console output
of ffprobe -show_streams ("ffprobe -show_streams Dolphins_720.wmv" and
also "ffprobe -show_streams Dolphins_7202_TMP.flv").
