I have a laptop running 18.04 with a Realtek ALC269VC card and Pulseaudio. The speakers are working normally. Same when plugging headphones. But the internal microphone is not. No sound is produced although I see the bar here going somehow back and forth.
Alsamixer configuration seems fine.
Already tried purging pulseaudio and alsa-base but no improvement. What could be the issue ? Thanks
