MMM-AssistantMk2 / MMM-Hotword Issue

BJ Duncan

No dramas at all.

Now you need to double check that you are pointing to the correct device number for your audio with the Assistant module.
In a terminal at the root directory (pi@raspberrypi:~ ) Check the device list for audio input:

arecord -l

This should provide you a list of CAPTURE Hardware Devices. The numbers you want to write down is the Card number, and device number.
As an example on my device I have it as Card: 2 Device: 0

Now within the config.js of the MagicMirror ensure that the device number is the same. Here is what it looks like within my config.js:

{
		  module: "MMM-AssistantMk2",
		  position: "bottom_bar",
		  config: {
		    record: {
		      recordProgram : "arecord",  
		      device        : "plughw:2",
		    },
		
		    notifications: {
		      ASSISTANT_ACTIVATED: "HOTWORD_PAUSE",
		      ASSISTANT_DEACTIVATED: "HOTWORD_RESUME",
		    },
		  }
		},
		{
		  module: "MMM-Hotword",
		  config: {
		    chimeOnFinish:null,
		    mic: {
		      recordProgram : "arecord",  
		      device        : "plughw:2",
		    },
		    models: [
		      {
		        hotwords    : "smart_mirror",
		        file        : "smart_mirror.umdl",
		        sensitivity : "0.5",
		      },
		    ],
		    defaultCommand: {
		      notificationExec: {
		        notification: "ASSISTANT_ACTIVATE",
		        payload: (detected, afterRecord) => {
		          return {profile:"default"}
		        }
		      },
		      afterRecordLimit:0,
		      restart:false,
		    },
		  },
},

Notice within both my modules because my card number is ‘2’, that the

device : "plughw:2",

So make sure your number corresponds with your Card number.

Give that a test and we will go from there.

arecord -l

I get this…

pi@raspberrypi:~ $ arecord -l

@JonoGee I recognised both devices as 0 so I changed accordingly. Now i get this error message. Mirror opens but closes immediately…

@JonoGee If devices are set as…

hw:0,0

The mirror works, but Assistant/Hotword doesm’t. I just changed to …```
plughw:0

and it crashes

What type of microphone is it? Is it USB?
Also, what version of Raspbian are you using? And is it Raspberry Pi 3+ ?

JonoGee

@BJ-Duncan
The Mic is a combined Speaker / Mic HAT as see here… https://www.raspiaudio.com/raspiaudio-aiy

I am running Raspberry Pi3+
Version…

pi@raspberrypi:~ $ lsb_release -a
No LSB modules are available.
Distributor ID:	Raspbian
Description:	Raspbian GNU/Linux 9.9 (stretch)
Release:	9.9
Codename:	stretch

Sorry @JonoGee mate, I may not be the best person to resolve as I have USB Mic so my settings will be different to yours.

I will attempt to do some research for you though and see if I can assist with a solution.

@BJ-Duncan
I realise both Speaker & Mic are on same Hat but does it make sense to you that the ID for aplay and arecord are exactly the same. Code included below…

pi@raspberrypi:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpigooglevoi [snd_rpi_googlevoicehat_soundcar], device 0: Google voiceHAT SoundCard HiFi voicehat-codec-0 []

pi@raspberrypi:~ $ arecord -l

pi@raspberrypi:~ $

JonoGee

@JonoGee I mean I supposedly I have to set both IDs in config file to hw:0,0.

JonoGee

@BJ-Duncan What Mic do you use mate? I might just buy same one.lol
