If I use null I get a black MMM screen.

If I use hw:0,0 I get the config.js message.

Finally if I use "hw:0,0" (with quotes) I get a black MM screen again.

Ok… Are you using Telegram?
I can give more direct help on Telegram. My id is @eouia.
Here is not so good place to talk these things.

Cr4z33

@Sean
Yep adding you right now. :)

citizendevpi

A Former User

@citizendevpi
:) You can also talk on Telegram. I prefer that then talking here. :)

I want to thank @Sean publicly for having helped me privately into solving the issue! :clapping_hands_medium-light_skin_tone: :thumbs_up_medium-light_skin_tone:

i cannot get hotword to detect any sound ?

@citizendevpi
More details are needed for detail answer.
you can set record.verbose: true for checking your mic works properly. But before that, you should confirm there was any other error to issue. Check your error log.

@sean arecord: main:788: audio open error: Device or resource busy and where is my error log?

A Former User

@citizendevpi
Your system seems not properly configured to use audio device. that might be not the issue of module itself.
And you can see the log with

pm2 log mm #or your registered process name for MagicMirror

or
stop pm2 then npm start dev in your MM directory.

A Former User

@citizendevpi
Anyway,
You should confirm to check your audio device card and name, and your RPI should be able to run below commands (or similar)

arecord -d 5 test.wav

or

arecord --device plughw:1,0 -d 5  test.wav

(plughw:1,0 might be different. You should find your proper device card and number with arecord -l)

@sean said in MMM-AssistantMk2 & MMM-GAction:

arecord --device plughw:1,0 -d 5 test.wav

A Former User

@citizendevpi said in MMM-AssistantMk2 & MMM-GAction:

arecord --device plughw:1,0 -d 5 test.wav

That works? If so, you can set your config record.device: "plughw:1,0",

@citizendevpi
Ok. forget my previous answer.

arecord -l

It’s l (small L), not 1 (one)

Your recording device is plughw:0,0. or default. Remember it.

Then try this.

arecord -d 10 test.wav

Say something. It will be record your voice to test.wav on 10 secs.
Works?

If so, then,

aplay test.wav

It should play previous recording from arecord. Can you hear anything?

citizendevpi

@sean yes barley
but yes

A Former User

@citizendevpi
Your Mic and Speaker are both the default. So, Now, show your config to me.
