Comment (by Mango):

 As you can see, ffmpeg wrote in the metadata:

 Metadata:

     encoder : Lavf56.36.100
     WAVEFORMATEXTENSIBLE_CHANNEL_MASK: 0x107
     Stream #0:0: Audio: flac, 48000 Hz, 4.0, s32 (24 bit), 128 kb/s

 ffplay and ffprobe don't show this, they only show:

   Metadata:
     ENCODER         : Lavf56.36.100
   Duration: 00:00:12.32, start: 0.000000, bitrate: 2740 kb/s
     Stream #0:0: Audio: flac, 48000 Hz, 4.0, s32 (24 bit)


 The WAVEFORMATEXTENSIBLE_CHANNEL_MASK: 0x107 is missing.

 Thanks.
