Hello community,
I have a problem with recording using arecord or /recordexamples/record.py from the 4MIChat Git repository with the Respeaker 4-mic array. I followed the getting started guide from ReSpeaker 4-Mic Array for Raspberry Pi | Seeed Studio Wiki and initially had no issues.
I installed the new Raspberry Pi OS kernel 6.1 on a clean Raspberry Pi 4. I connected the Respeaker and a USB headset to a USB bus. The installation of the getting started documentation was successful.
Here is my asound.conf:
# The IPC key of dmix or dsnoop plugin must be unique
# If 555555 or 666666 is used by other processes, use another one
# use samplerate to resample as speexdsp resample is bad
defaults.pcm.rate_converter "samplerate"
pcm.!default {
type asym
playback.pcm "playback"
capture.pcm "ac108"
}
pcm.playback {
type plug
slave.pcm "hw:3,0"
}
pcm.ac108 {
type plug
slave.pcm "hw:seeed4micvoicec"
}
When using arecord -L
, I get:
null
Discard all samples (playback) or generate zero samples (capture)

I have already tried pixels.py
, and the LEDs light up without any problems. However, when I use record.py
form the documentation in the 4MicHat repository or just arecord
and use the command arecord -Dac108 -f S32_LE -r 16000 -c 4 hello.wav
for recording, my Raspberry Pi crashes, and I have to use the power switch to restart the pi.
I already try to connect the respeaker 4mic array directly into the pi but nothing worked for me. i have no clue what im doing wrong.
Any help is appreciated.
