I have a blog on PulseAudio I would ask you to read. Nothing in hardware is not normal and is most often associated with upgrades (12.2 to 12.3) OR by copies of user area into an existing system. Read the blog, check out the links. I have one for my start bash sctipt that might be useful.
This sounds much like a permissions issue.
Adding your user to the “audio” group should fix it.
sudo usermod -a -G audio $USER
But: since your user should get the necessary permissions at login, something seems to be wrong there which may cause you other problems as well (network, USB devices, video, …)
So please post the output of those commands to check:
Right. A re-login is needed for that group change to take effect.
But as I said, if you don’t solve the underlying problem why your user doesn’t get those permissions in the first place, you will have other problems as well (like having to enter the root password for suspending, mounting USB drives and so on).
So again, please post the output of “loginctl” to see if there’s a problem with registering your user’s session.
