Hello-Lucy using Adafruit Voice Bonnet
-
I’m trying to bring up Hello-Lucy on a “new” Magic Mirror. I’m running on a Pi 3B+, and installed the Adafruit Voice Bonnet for audio.
I can do
arecord --format cd --duration 7 --channels 1 test2.wav
then
aplay test2.wav
and I hear the recording from the Voice Bonnet speaker. I don’t have to specify he device for these to work.When I list my audio devices, I get:
pi@Magic:~/MagicMirror/config $ aplay -l

Subdevices: 1/1
Subdevice #0: subdevice #0Card 2 for both play and capture is the Voice Bonnet.
When I restart MMM with Hello-Lucy, I hear the default greeting, but always get the microphone shown with ERROR. Even though the lists indicate card 2, I’ve tried 0 and 1 since card 2 is the only thing listed, but still no microphone.
Here’s my config.js file:

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.

so it should be
microphone: “2,0”,Thanks for replying. This config is what I had when I posted. As I mentioned, I’ve tried “0,0”, “1,0”, and “2,0”; all result in the microphone error.

@sinbad339 can u try this
arecord -D default -q -r 16000 -c 1 -t wav -f S16_LE >test.wavthe replace default with
arecord -D hw:2,0 -q -r 16000 -c 1 -t wav -f S16_LE >test.wav -
@sdetweil
With MM running, if I issuearecord -D default -q -r 16000 -c 1 -t wav -f S16_LE >test.wavI get a good .wave file that I can play.
With MM still running, specifying the hw explicitly results in an error.arecord -D hw:2,0 -q -r 16000 -c 1 -t wav -f S16_LE >test2.wav arecord: main:830: audio open error: Device or resource busy pi@Magic:~/MagicMirror/config $ arecord -l **** List of CAPTURE Hardware Devices **** card 2: seeed2micvoicec [seeed-2mic-voicecard], device 0: bcm2835-i2s-wm8960-hifi wm8960-hifi-0 [bcm2835-i2s-wm8960-hifi wm8960-hifi-0] Subdevices: 0/1 Subdevice #0: subdevice #0 -

ok, so MM is using that device
while mm is running do
ps -ef | grep arec
u should see the arecord process and the parms passed
from one of my apps that uses arecordarecord -D default -q -r 16000 -c 1 -t wav -f S16_LE -the trailing dash means stream content to stdout (which is captured by the upstream library)

@sdetweil
So the arecord -l lists card2 as my expected capture device (seeed-2mic-voicecard). I find it interesting that it enumverates as #2 with no #0 or #1.Anyway, I ran your ps command; not sure what this output means (as I’m sure you’re aware by now, I’m a Noob on Linux).
ps -ef | grep arec pi 1953 1927 0 11:04 pts/0 00:00:00 grep --color=auto arec -
@sinbad339 hm…
should have used arecord…
try
ps -ef | grep rec(there are only 2 apps… arecord or rec )
the output from ps
pi 1953 1927 0 11:04 pts/0 00:00:00 grep --color=auto arecuser that started process
the process id
the parent process id +
(i don’t know, 0)
the time the process was started
(i don’t know, pts/ )
how much cpu time has been used since started, in seconds
the string used to start the process, pgm name and then parms -
ps -ef | grep rec root 76 2 0 11:02 ? 00:00:00 [vchiq-recy/0] pi 2320 1927 0 11:24 pts/0 00:00:00 grep --color=auto recNot sure what vchiq-recy is…
But no arec or arecord.
