Comment (by MasterQuestionable):

 ͏    Perhaps try other channel descriptions?
 ͏    Per:

 stereo-using-ffmpeg#1663861

 ͏    The "channelmap" is just copied from documentation without actual
 change.
 ͏    Maybe itself invalid..? ("DL" "DR" be error?)
 ͏    [ !^ Probably just bad example. ]
 ͏    See also: https://ffmpeg.org/ffmpeg-utils.html#Channel-Layout

 ͏    I generally use Mono directly and not bothering these peculiar
 layouts.
 ͏    (arrange remix explicitly on need)
