Hi,
I downloaded Armbian Bionic for OrangePi Lite from:
https://www.armbian.com/orange-pi-lite/
and everything works fine, except audio recording from microphone.
Error:
root@orangepiserver:~# arecord test.wav
ALSA lib confmisc.c:767:(parse_card) cannot find card '0'
ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM default

Have You any idea how to fix it?
In theory this microcontroller has a microphone. Anyway, I also tried an external USB microphone and there is still a problem.
