This was only just recently asked (and answered):

Not according to my expectations either, but apparently that's the way

Thank you, I didn't notice that this has been discussed just recently.
We have to add -ac 2 or use 


-af aresample=matrix_encoding=dplii:out_channel_layout=stereo


Kind regards
Bernd
