How to list available audio i/o devices in Bash

Question

Is there a Terminal command I can use to list available audio devices on my Mac, running osx??? I've had no luck with (arecord -l) | (aplay -l).

Thanks in advance. Hopefully this isn't a repeat question, although I've been searching far and wide...

I guess the best you can do is typing system_profiler SPAudioDataType, then you can format the output with sed/grep/awk. It's what I do when I want to list USB devices in osx, for example.
