Running journalctl -p 3 -b i get infinite rtkit-daemon logs in which apparently some rtkit function cannot find an UID.
The messages are like this:
lug 24 21:07:45 alex-eos rtkit-daemon[860]: dbus_message_get_unix_user() failed: Could not get UID of name ':1.41': no such name
I understand that could be some audio issue.

There was just another pipewire update. Maybe it fixes your issue?
welcome @crotalo have fun on the purpleroads 
looks mor elike an issue with dbus and username and group not evenly setup (what should be that automatiocally)
sudo pacman -Sy dbus reinstalling dbus… could solve it… it simply looks screwed Could not get UID of name ':1.41': no such name
Thank you @joekamprad !
I tried resinstalling dbus but the log is still there.
Using $find /etc/systemd -name *.service -type l -a -xtype f -printf %f\n;
i just saw that i am running wireplumber and pipewire-session-manager.
Is it okay to have them both up?

This is only a part of the output since i get a new entry every second or so.
I am thinking on reinstalling from scratch, i have no idea on what’s happening 
wireplumber.service
pipewire-session-manager.service
these are different things … you may thinking of pipewire-media-session
… what would replacing wireplumber …
still thinking something with dbus is gone mad on you…
D-Bus is completely under control from systemd now on arch so this is nothing you would setup on your own or edit any configs for…
rtkit ? could be the culprit too 
systemctl status rtkit-daemon.service
you can try restarting it to see if it stops the spamming:
sudo systemctl restart rtkit-daemon.service
I just logged in today, and the spam issue seems to have disappeared. It’s a bit puzzling because I’m not entirely sure what caused it to go away. However, I can share some recent changes I made, which might be related (I am currently Dualbooting Linux and Windows on two separate SSD):
- I switched linux time to RTC, before was localtime to avoid sync problem with windows.
- Removed an i3block script i had wrote to check controller battery status, which inside was calling upower (some guy on the internet had the same issue and he also had a script calling upower, and he fixed it by deactivating it).
- I installed realtime-privileges and added my user to the realtime group.
- I reinstalled brutally rtkit with “$ sudo pacman -S rtkit”
The issue seemed to persist even after implementing these changes and with consequent reboots.
Today i just logged in on windows until now.
I’m still not sure which specific change resolved the problem or if the Windows login had any influence, but i am definitely happy it went away.
Thank you for the help!
This is rtkit status at the moment.

This shouldn’t have anything to do with it.
