lomiri: Pulseaudio fails to connect to ayatana-indicator-sound while Pipewire connects

Describe your issue

Pulseaudio fails to connect to ayatana-indicator-sound with

ayatana-indicator-sound-WARNING **: 22:26:07.827: volume-control-pulse.vala:756: unable to get pulse unix socket: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.PulseAudio1 was not provided by any .service files

Pipewire-Pulse is able to connect while still getting this error.

This needs to be fixed as we do not support Pipewire as of yet.

What's the expected behaviour?

Pulseaudio works with ayatana-indicator-sound.

What's the current behaviour?

Only Pipewire works with ayatana-indicator-sound.

Install Pulseaudio with Lomiri.

Additional information

There is also the warning: libnotify-WARNING **: 22:26:07.866: Failed to connect to proxy, but this should not cause audio to fail.

This could also just be a configuration error with Pulseaudio, but I am filing this for future reference.
