Needed: audio in/out device info

This board may be a great target for our esp-adf app that needs to simultaneously read mic input and write speaker output.

Are there demo apps that do this?

Also: I can do low level hacking: I can’t find doc on your site describing the codecs and how they’re wired.

Thanks, Eric

hi just to be sure are you refering to this board?

if yes as it is Linux it is easy to play and record at the same time ( notice the ‘&’:

speaker-test -D plughw:2,0 -l5 -c8 -t wav &
arecord -D plughw:2,0 -c8 -f S32_LE -r 48000 test.wav
