And I could use a general explanation:
Whats Aux_sel for?
what are Aux_R and Aux_L for? can I use the to input audio that I want the respeaker to play? ( so it gets used with AEC)
I need to convert all my audio to 16khz before inputting it? (in case the above is even possible)
if it the two aux pins are audio out, then how does the reapeaker core sneds the mic array the audio to play?
At least I could not really find the explanations in the respeaker mic array v2 documentation
