Pulseaudio not detecting mic after @world upgrade



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:


? ~ dmesg | grep HDA

[    4.779666] input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/sound/card0/hdaudioC0D0/input5
[    4.779911] input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input10
[    4.779938] input: HDA Intel PCH Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input11
[    4.779964] input: HDA Intel PCH HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:1b.0/sound/card0/input12


But if I do pacmd list-sources, I only see a monitor.


1 source(s) available.

                device.form_factor = "internal"
                device.string = "0"
                module-udev-detect.discovered = "1"
                device.icon_name = "audio-card-pci"




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.
