Obviously.
(The wav standard does not require writing the channel layout for some
mono and stereo files and we don't do it to maintain compatibility with
ancient software that fails if the information is present.)

This warning is not meant for you and you cannot fix it.

For future questions: Please understand that posting excerpts of the
