In this situation, it is always good to check what others are using :)

In this case, all the input devices seem to use "channels":

https://github.com/FFmpeg/FFmpeg/blob/master/libavdevice/alsa_dec.c#L146
https://github.com/FFmpeg/FFmpeg/blob/master/libavdevice/dshow.c#L1269

Indeed, -ac is actually mapped to "channels" within the ffmpeg program:
https://github.com/FFmpeg/FFmpeg/blob/master/ffmpeg_opt.c#L900
