I don't understand this question;-(
Did you already test the option?
If not, that would explain your question and
why I cannot answer it.
(You have to specify the option 16 - or at least
14 - times.)

The fact that FFmpeg tries hard to guess a channel_layout
for every audio input is a regression; it couldn't be
fixed until very recently because of some (very broken)
changes to FFmpeg, I believe this has been fixed now (ie
audio without channel layouts should be supported again).
I am not convinced anybody is working on reverting
"always guess a channel layout", probably because
developers do not see this as a bug.
