Can anyone point me in the right direction for an Armbian image that would allow audio recording over the 3.5mm jack? I'm trying to record audio over the 3.5mm jack. This works on a previous installation, but I'm trying to update to a curreent Armbian.

Running Tinkerboard S R2.0 and this image:
Armbian_25.2.1_Tinkerboard_noble_current_6.12.13_xfce_desktop.img

 

Playback works record does not. 

Works:

aplay /usr/share/sounds/alsa/Side_Right.wav -D hw:CARD=Audio,DEV=2

 

None of the following arecord commands work:

arecord --vumeter=mono -D hw:CARD=Audio,DEV=0 -f S16_LE -c 2 -d 5 /tmp/t.wav
arecord --vumeter=mono -D hw:CARD=Audio,DEV=1 -f S16_LE -c 2 -d 5 /tmp/t.wav
arecord --vumeter=mono -D plughw:CARD=Audio,DEV=0 -f S16_LE -c 2 -d 5 /tmp/t.wav
arecord --vumeter=mono -D plughw:CARD=Audio,DEV=1 -f S16_LE -c 2 -d 5 /tmp/t.wav
arecord --vumeter=mono -D default:CARD=Audio -f S16_LE -c 2 -d 5 /tmp/t.wav
arecord --vumeter=mono -D sysdefault:CARD=Audio -f S16_LE -c 2 -d 5 /tmp/t.wav
arecord --vumeter=mono -D front:CARD=Audio,DEV=0 -f S16_LE -c 2 -d 5 /tmp/t.wav

Hi,

 

could it be that the mic is muted or volume is too low?

You might check the situation with alsamixer (then F4 for capture controls).

Thanks! That was the issue. 


alsamixer > F4: Volume was low/off and Capture was not enabled (SPACEBar). Hitting the spacebar with the channel selected put the red text "CAPTURE".

Correction to original post, I have  typo and did not put in "plug" for plughw.

 aplay /usr/share/sounds/alsa/Side_Right.wav -D plughw:CARD=Audio,DEV=2
