Hi there,
I'm running Bullseye 32 bit on a Pi Zero W with the MEMS microphone. I'm using Bullseye because the scripts I am using for this project were developed on Bullseye and it's just faster for me to use that version (though I am willing to go to Bookworm if necessary). The install was working until lately.
I have tried the fixes in
this post but I'm still getting the following errors:

DONE.
Has anyone used the MEMS mic on a Pi Zero W and if so, how did you get it to work? Thanks in advance!

I ordered a sensor so I can help smooth out the process.
It looks like the main resolution was to add these two lines to the /boot/config.txt:
Code: Select all
dtoverlay=googlevoicehat-soundcard
dtparam=i2s=on
It is not clear that a custom build of the modules is necessary to get up and running.

Thanks for the help! I put both of those in the /boot/config.txt and rebooted first, then followed directions on the product page. I am still getting the following errors:

These are the necessary settings based on the last group thread. I think the necessary modules are present already and it is just this bit of configuration that needs to be in place.
I'll confirm in a few days when the MEMS mic arrives, but might be all that is necessary:
config.txt :
Code: Select all
dtparam=i2s=on
dtoverlay=googlevoicehat-soundcard
arm_64bit=0
/etc/asound.conf :
Code: Select all
pcm.dmic_hw {
type hw
card sndrpii2scard
channels 2
format S32_LE
}
pcm.dmic_sv {
type softvol
slave.pcm dmic_hw
control {
name "Mic Capture Volume"
card sndrpii2scard
}
}
pcm.!default {
type asym
playback.pcm "plughw:0"
capture.pcm "dmic_sv"
}
ctl.!default {
type hw
card 0
}
skip the installer and see if your I2S device is visible.

The SPH0645 mic arrived and upon reboot I was able to see the device and produce a recording just by adding a single line to the /boot/config.txt:
Code: Select all
dtoverlay=googlevoicehat-soundcardCode: Select all
arecord -D plughw:1 -c1 -r 48000 -f S32_LE -t wav -V mono -v file1.wav
The audio file recorded fine and played back well.
This setup was on a Pi 4B running Bullseye 64-bit Legacy Lite (2024-03-12). No updates applied and I did not run the adafruit i2smic.py script.
I'll setup the same now with a 32-bit Pi Zero W to match your setup.

I was approved to update the guide to use this one-line modification. I'll post an update when that is complete tomorrow.

I updated
the guide page to no longer go through the i2smic.py installer method and use the one line googlevoicehat driver. Repair discussion in Raspberry-Pi-Installer-Scripts
#320 .
My testing shows it worked on these setups.
