Hi,
I got a new nano pi neo air and wanted to add a microphone to record sound. First I tried my USB mic and it worked without any problem then I saw a topic in here:
https://forum.armbian.com/index.php?/topic/3598-nano-pi-neo-air-mic-audio-out/
According to this topic, I can attach a mic to the pins that mentioned. But my big problem is what is the hardware name?
I tried to use
arecord -l
and the output was:
root@NanoPi-NEO-Air:~# arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: sndhdmi [sndhdmi], device 0: SUNXI-HDMIAUDIO sndhdmi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
But it is the HDMI sound card which I think is not right.
How can I record sound with the attached mic?
Thanks.
