Hi,
I bought USB 3D sound card adapter since my Pi3 hasn’t Mic port and than i connected my jack 3.5 Microphone to it .

If you have another USB HD camera with built-ed Mic you have to disable it since it will not work properly with your speech recognition software. I faced recently with this problem. I couldn’t configure it.
If you have USB HD camera with built-ed Mic please let me know and i show you how to disable it.
Best,

I think it could be related with permission of account.
As I know, Alexa Pi is running with Deamon mode, it means, the account of Alexa Pi is different with your personal account which you had tested audio with.(maybe pulse audio)
I have no idea how to solve because I’m not an expert, but most of the cases seem to be related to that point in using Alexa Pi.

Can you record and play with these commands? Does it work?

arecord -d 10 test.wav && aplay test.wav

I’m not an expert, but Only I can say is…

• The error message caused by sound configuration fail.
• AlexaPi cannot understand your device “plughw:…” currently.
• I think it is related to alexapi daemon account and your personal account settings.
• https://github.com/alexa-pi/AlexaPi/wiki/Audio-setup-&-debugging This could be helpful.

Anyway, this is not realted with MagicMirror. You’d better get help from AlexaPi develpers or users on gitHub(or wiki)

Since i installed 3D sound card(external USB card with speaker and Mic) i disabled other internal HD web camera’s Microphone which came with my Touch Screen monitor. I used usual 3.5 mm jack mic.

1. Go to- -> sudo nano /lib/modprobe.d/aliases.conf
##options snd-pcsp index=-2 - This is my USB Mic which is came with internal HD camera on my monitor.
options snd-usb-audio index=-2
options cx88_alsa index=-2
options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2

2. Go to --> sudo nano /etc/modprobe.d/raspi-blacklist.conf and added below command
blacklist snd_bcm2835

Above “snd_bcm2835” is my internal sound card

That’s all.
