Ubuntu 22.04 desktop.
I haven’t found anything on this… how can I test out the microphones on the VIM4 ?
Thank you !
Hello @p2_83
Can you try to upgrade the kernel and try again?
Upgrade the kernel:
cd /tmp/
wget https://dl.khadas.com/.test/linux-image-amlogic-5.4_1.3_arm64.deb
wget https://dl.khadas.com/.test/linux-dtb-amlogic-5.4_1.3_arm64.deb
sudo dpkg -i linux-dtb-amlogic-5.4_1.3_arm64.deb linux-image-amlogic-5.4_1.3_arm64.deb
sync
sudo reboot
After reboot, you can record from DMIC.
Recode from DMIC:
arecord -Dhw:0,4 -r 48000 -f S16_LE -c 2 -d 10 test.wav
