Since the last upgrade, pulseaudio doesn't load any mic. I sometimes use the internal mic from the notebook, and sometimes I connect an external one. The profiles in pavucontrol only show "analog stereo output", and they used to show "analog stereo duplex". I see the mic is detected with dmesg:
But if I do pacmd list-sources, I only see a monitor.
I don't know what I should do to recover the mic. My /etc/pulse was not modified in the last upgrade, so I am a little lost.
