Or do you mean "how to list alsa devices"?
$ aplay -l
lists the alsa output devices
$ arecord -l
lists the alsa input devices.
There is of course a semantic difference between the
FFmpeg devices (for example "alsa") and the alsa
devices (like "card 1" "device 7" which translates
to "hw:1,7" in FFmpeg's alsa notation).
