Unmuted onboard microphone with alsamixer in "Playback" section - i hear sound from onboard microphone when unmuted - microphone is working itself.
Selected MIC1 in "Capture" section in alsamixer
Then i've tried to record audio with this commands and always got a file with silence:
sudo arecord -c 2 --rate 48000 --device=hw:0,0 --duration=10 --format=S16_LE test.wav
sudo arecord -c 1 --rate 48000 --device=hw:0,0 --duration=10 --format=S16_LE test.wav
sudo arecord -c 2 --device=hw:0,0 --duration=10 --format=S16_LE test.wav
When i'm recording from usb camera - i'm getting file with correct audio:
sudo arecord -c 2 --rate 48000 --device=hw:2,0 --duration=10 --format=S16_LE test.wav
