On Linux I have an 18 channel wav file that I can play with aplay or play(sox) without problems. The 18 channels are played well. If I want to play it with ffplay I get this:
libavutil 56. 51.100 / 56. 51.100
libavcodec 58. 91.100 / 58. 91.100
libavformat 58. 45.100 / 58. 45.100
libavdevice 58. 10.100 / 58. 10.100
libavfilter 7. 85.100 / 7. 85.100
libavresample 4. 0. 0 / 4. 0. 0
libswscale 5. 7.100 / 5. 7.100

Invalid sample rate or channel count!
Failed to open file 'projetks2.wav' or configure filtergraph
why ? and how to fix this?
ffplay -layouts. There is probably a way to mix down the channels to say 16 channels before playing. What is the actual "hardware" layout of your system?
