Following the instructions from MMM Awesome Alexa by dolanmiu regarding the audio setup, on my asoundrc if I remember correctly, I used the following commands and this somehow solved my problem.

pcm.!default {
    type asym
    playback.pcm "plughw:0"
    capture.pcm  "plughw:1"
}

all good guys, solved it. Thanks all

Here is my current setup; as for my asoundrc,

pcm.!default {
    type hw
    card 0
}

ctl.!default {
    type hw
    card 1
}

From my understanding, c from ctl is for capture so I tried selecting my webcam. However, whenever I ran this code – this shows up

arecord --format cd --duration 15 --channels 1 test.wav 
-> arecord: main:788: audio open error: No such file or directory

Of course I can resolve this by changing my asoundrc, pcm and ctl to 1 and this error would not show up however, whenever I try playing the recording, I am not hearing anything.

My end goal is to have my camera as my audio input and the audio output just the default which in my case is my monitor speakers.

I am not sure what happened to my first post, I apologize if I broke any rules the first time but here it goes again.

I am relatively new in RPi3B and Magic Mirror (about 3-4 days), and so far I have managed to complete steps up to the installation of Alexa module on my RPi. For my video and audio input, I have decided to go with a Logitech C170 as I’ve seen from a wiki that it can work with RPi.

I tested the camera with Cheese and it seems to be working fine. As for its mic, I got it to work with this command (from the sunfounder wiki)

arecord -D plughw:1,0 -d 3 test.wav && aplay test.wav

However, when it comes to calling up Alexa, it seems to be not responding to my wakeword and I think it’s not “listening” in the first place. I really appreciate your help.

EDIT: Is a better solution to just buy a separate USB Mic and disable the mic on the camera so I could get the alexa working? However, I do think I am missing something (maybe in the codes but I think I followed the instructions clearly).
