Hi everyone!
I am struggling with audio input.
Output audio from LINEOUT pins works fine out-of-the-box!
What about the audio input?
To begin with I have tested the arecord command with these error messages…
TEST 1
root@rockpi-s:~# arecord -f S16_LE -d 10 -r 16000 --device=“hw:0,0” test-mic.wav
Recording WAVE ‘test-mic.wav’ : Signed 16 bit Little Endian, Rate 16000 Hz, Mono
arecord: set_params:1358: Channels count non available
TEST 2
root@rockpi-s:~# arecord -f S16_LE -c 2 -d 10 -r 16000 --device=“hw:0,0” test-mic.wav
Recording WAVE ‘test-mic.wav’ : Signed 16 bit Little Endian, Rate 16000 Hz, Stereo
arecord: set_params:1416: Unable to install hw params:
