I have an Alexa DDK: Amlogic A113X1 Far-Field Dev Kit
I want to record processed audio file from this DDK, but I do not know what should I set for the -D parameter.
arecord -f S32_LE -r 48000 -d 10 -c 8 -D ? test.wav
(The parameter for -D looks should be defined in the /etc/asound.conf, anyone could help confirm on this device?)
