Comment (by cus):

 Correct me if I am wrong, but as far as I know -ac 2 is used to override
 the detected audio channel count, and not to specify the requested channel
 count.

 You may use

 SDL_AUDIO_CHANNELS=2 ffplay yo10.wav

 if you want to force ffplay to open audio output with two channels and
 upmix the sound properly.

 May I close this as invalid then?
