 Replying to [comment:30 heleppkes]:
 > What you think is 3/1 is what ffmpeg calls 4.0

 properly carry a channel layout when playing raw PCM, thats entirely
 unrelated to how the audio was encoded.

 Ok, so VLC, kodi, etc.. are at fault. I'll report this to them. Thanks.

 As I understand there is nothing wrong So:

 1. Can you remove the red error on encoding?

 2. have ffplay and ffprobe show the correct 3/1 (next to 4.0) and Channel
 positions: Front: L C R, Back: C like mediainfo so that we can see this
 important information.
