MMM-AssistantMk2 / MMM-Hotword Issue

BJ Duncan

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

@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

card 0: sndrpigooglevoi [snd_rpi_googlevoicehat_soundcar], device 0: Google voiceHAT SoundCard HiFi voicehat-codec-0 []

pi@raspberrypi:~ $ arecord -l

@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

Hey @JonoGee, mate I have been researching but to no avail. Sorry mate on that. I’m just not too familiar with your set up.
The Mic and Speakers I got are just some cheap USB type models.
Speakers | Mic

If you do go by this type of setup then the previous code I placed up should work #fingersCrossed ;-)
