Description:

Yesterday I upgraded pulseaudio to 12.0-1 and discovered that the service doesn't start anymore:

```
eax@e733:~$ pactl list sinks short
Connection failure: Connection refused
pa_context_connect() failed: Connection refused

eax@e733:~$ systemctl --user start pulseaudio
Job for pulseaudio.service failed because the control process exited with error code.
See "systemctl --user status pulseaudio.service" and "journalctl --user -xe" for details.

eax@e733:~$ journalctl --user -xe

eax@e733:~$ sudo fuser -v /dev/snd/*
[sudo] password for eax:
USER PID ACCESS COMMAND
/dev/snd/controlC0: eax 706 F.... pulseaudio
/dev/snd/controlC1: eax 706 F.... pulseaudio
```

As a workaround I downgraded Pulseaudio packages:

```
sudo pacman -U libpulse-11.1-1-x86_64.pkg.tar.xz pulseaudio-11.1-1-x86_64.pkg.tar.xz
```

..., added them to IgnorePkg list in pacman.conf and rebooted, this solved the issue. Obviously something is broken in new packages.
