MM + Alexa + Logitech C170?

I think most of the cases, Your ALSA setup (or If you use, PulseAudio) might be wrong. Make that mic to be the default input of your system, or configure your Alexa module to point the proper device id.

ps. Also me once used Logitech Webcam as mic and camera. PS3Eye also worked in my experience.

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.

It’s for PS3Eye but you can get the idea.

Added

pcm.!default {
    type asym
    playback.pcm {
        type hw
        card 0
    }
    capture.pcm {
        type hw
        card 1
    }
}

ctl.!default {
    type hw
    card 0
}

I think this might be a point.

Please post a detailed explanation of how you solved this for the next person that may encounter this issue.

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"
}
