Public bug reported:

Hello,

Since I've upgraded to 24.04, I oftently have no sound at startup with
"dummy output" in sound settings.

Each time I need to "sudo apt-get install --reinstall alsa-base alsa-
utils pipewire" then reboot for the sound to come back.

Sometimes, sound is lost at wake up.

Upgrading to 24.10 didn't fix the problem.

That's painful. Hope this helps.
