"-ac 2" probably forces ffprobe to assume that the *input* has two
channels, which apparently isn't supported.
Did you read Carl Eugen's suggestion to try "-af aresample=ocl=stereo"?

I believe it's SDL which has the ALSA implementation, ffplay only uses
the SDL API. (I may be wrong though.)
ffplay is sort of minimalistic feature-wise. Do you definitely need
ffplay? Do you have access to mpv?
