OrangePi PC 4 LTE microphone issue

[Mr. Fennec]

Hi, I installed recent server armbian on orangepi pc 4 and trying to make the microphone work

The command I use 

 

arecord -D hw:0,0 -f cd -d 5 test.wav

 

The setup

root@orangepi4-lts:~# uname -a
Linux orangepi4-lts 6.6.62-current-rockchip64 #2 SMP PREEMPT Sun Nov 17 14:08:59 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux
root@orangepi4-lts:~# cat /etc/issue
Armbian 24.11.1 Noble \l 

root@orangepi4-lts:~# arecord -l

What could be the issue?

I tried to change alsamixer levels, but it didn't help. I still hear just some white noise when listen to test.wav

Any ideas ?
