Hello-Lucy using Adafruit Voice Bonnet

The difference is how MM is started. If I do it the manual way, the microphone works (with or without debug enabled). If MM does its normal autostart, using mm.sh that includes DISPLAY=:0 npm start, then the microphone doesn’t work.

@sinbad339 said in Hello-Lucy using Adafruit Voice Bonnet:

its normal autostart,

how is that done? pm2 or did u do some other setup

sounds like mm is not running as user but as root?

I followed the instructions from https://www.magicmirrorcentral.com/complete-raspberry-pi-magic-mirror-tutorial/.
It included

type in the following command:

pm2 startup
 
A different command will appear. Run that command also.

Now create a shell script for startup. Open up the built-in text editor on the Pi by typing in:

cd ~
nano mm.sh
The lower line basically means, “open up a file called mm.sh in the nano text editor.”

When the text editor has opened, add this to the mm.sh file:

cd ~/MagicMirror
DISPLAY=:0 npm start
Make your shiny new script executable by typing in:

chmod +x mm.sh
Now start up Magic Mirror and make it start up on boot:

pm2 start mm.sh

pm2 save
Now, reboot your Pi by typing in

sudo reboot

@sinbad339 hm… my install script does all that.

mm.sh already exists in the installers folder.

try my fixuppm2.sh from here

Let me start by saying I really appreciate your help with this. You’ve given me a lot of your time, and clearly I couldn’t have made any progress without you. Thank you.

Running your fixupppm2 script fixes the microphone on a restart, but then there is no speaker output. If I stop MM, then manually restart it with npm start, the mic and speaker work fine, as before the fixup.

@sinbad339 that makes no sense to me.
could u start it w pm2, and then ps -ef >somefile.txt

and email me thevfile some file.txt

same userid as here at gmail.

I want to see if there is some permissions problem

oh, check the file contents to make sure no userid or password is exposed. shouldn’t be but u never know.

@sdetweil
Just sent it…

[sinbad339]

Just sent two additional files; one where the speaker worked, and one where it didn’t. As I explained in the email, this is an intermittent issue and it doesn’t matter how MM is started.

Well, I gave up on the Adafruit Voice Bonnet, and instead installed a USB microphone with output (Samson GoMic). Now, mic and speakers work every time whether MM/Hello-Lucy starts up automatically at boot, or if I start it using npm start.

I’ll probably mark it resolved, even thought the fundamental issue is not.

A BIG thanks to @sdetweil for all of his patience and help.
