MMM-AssistantMk2

MarkV

I’ve installed MMM-AssistantMk2 with MMM-Hotword and MMM-NotificationTrigger.
Everything works fine except for the return audio.
It stutters and i’m getting the idea that it isn’t procest quick eneough.

Am i the only one with this problem and if not does somebody have the solution?

There could be many reasons for that case.
Maybe too many modules or too many front-end refreshing or animating, too many background process or anything else, even including internet speed.
I cannot point specific reason at this moment.
Anyway in my device, I use BT speaker and I have no problem about that. Sorry.

@sean
Thanks for the reply.
I was scared of something like that. After a clean raspbian image i just installed MagicMirror and after that MMM-AssistantMK2, MMM-Hotword and MMM-TriggerNotification (with all the nmp rebuild errors). I’ve uninstalled the compleet LibreOffice and game packets wich come by default with raspbian.

I allready made a .asoundrc file like you can find around the internet.
aplay && arecord work fine without glitches.

Result .asoundrc

pcm.!default {
  type asym
  capture.pcm "mic"
  playback.pcm "speaker"
}
ctl.!default {
        type hw
        card 0
}
pcm.mic {
  type plug
  slave {
    pcm "hw:1,0"
  }
}
pcm.speaker {
  type plug
  slave {
    pcm "hw:0,0"
    rate 18000
  }
}

What would you suggest doing now? I’m a little stuck now, due to my lack of knowledge of Linux.

@sean What are you using for a mic?

@teitlebot
I’m using logitech usb cam currently. Before that, Ps3eye, cheap chinese usb mic were tested.

i’m using a cheap chinese usb mic :grinning_face_with_smiling_eyes:

just to update and help. I reinstalled everything without the AIY Google HAT and just using a usb mic and the issue of the audio choppiness went away. Still working on other issues like no kiosk mode and learning this complicated google home interface stuff but its really cool.

teitlebot

@markv have a look at this if your mic isnt working

@jomwells @Module-Developers
Did anyone figure out how to add led or sound, like a beep to show when google is listening and speaking. I dont think I’m good enough with linux to do this without a tutorial. Is it something that needs to be implemented in the module or can i learn how to do it from a simple aiy kit?

https://github.com/eouia/MMM-AssistantMk2#outgoing-notifications-as-assistant-response
Basic notifications will be emitted by its status.
And you can modify module for catching the status to do your specific job.
See https://github.com/eouia/MMM-AssistantMk2/blob/93d7eca6a3995987554d8deb4f4cd76b44e3f096/MMM-AssistantMk2.js#L264
In .socketNotificationReceived(), you can catch each Assistant status.

Anyway, I’m considering to add simple ding-dong waves for convenience in next patch.
