Hi, I am using the 4 mic array for Rasberry Pi. When setting this up with the Alexa Module for my smart mirror, I keep running into audio errors. Here I have set up the microphone exactly as instructed on the wiki link after doing this and setting up my soundcard, I have tried using the command to test the microphone (provided by my Alexa programs audio set up instructions:
arecord --format cd --duration 15 --channels 1 test.wav
I believe that the command needs to look like this as this is the format that the program accepts, but honestly am not sure. Whenever I do this I get an assortment of errors. I am extremely new to Raspberry Pi’s, so any insight or help would be very much appreciated. Looking at the audio soundcard link I used may be helpful. Thank you so much!
