Pavucontrol can't connect to pipewire-pulse

pavucontrol stuck at "Establishing connection to PulseAudio. Please wait..."
Although the sound plays fine both through the built-in speakers and bluetooth headphones.

Tried to reinstall some packages, it didn't help:

Any insights or suggestions would be greatly appreciated! Thanks in advance!

Re: Pavucontrol can't connect to pipewire-pulse

If i start pipewire-pulse in terminal, it works. Do I just have to manually start it after every boot?

Re: Pavucontrol can't connect to pipewire-pulse

Your "enabling services manually" lacks the pipewire-pulse service. While it should get socket activated, enabling it additionally shouldn't hurt anything.

Re: Pavucontrol can't connect to pipewire-pulse

Thanks for pointing that out! I've actually tried this before:

$ systemctl --user enable --now pipewire wireplumber pipewire-pulse.service
Failed to enable unit: File '/home/user/.config/systemd/user/default.target.wants/pipewire-pulse.service' already exists

Upd: This command helps if I run it after every reboot:

$ systemctl --user restart pipewire wireplumber pipewire-pulse.service
