After upgrade to 24.04.01 LTS no audio device was available (neither speaker nor mic).

I tried some debug with:

sudo dmesg | grep -i alsa
sudo dmesg | grep -i snd
lspci | grep -i audio
aplay -l

And:

$ systemctl --user status pulseaudio
Unit pulseaudio.service could not be found

(It is ok, 24.04 uses pipewire)

systemctl --user status pipewire-pulse
systemctl --user status  wireplumber

Everything was ok.

There was a problem here:

$ systemctl --user status pipewire
