PulseAudio not detecting speakers at all

So my Arch system - presumably after me configuring some Xrdp shit - ceased detecting my speakers.

PulseAudio does not detect my speakers now. Now there are just dummy output devices.
pacmd list-sinks:

nphuracm@nphuracm-Arle-A ~> LC_ALL=C pacmd list-sinks

                device.icon_name = "audio-card"

Relevant output of lspci -nnk:

        Kernel driver in use: snd_hda_intel
        Kernel modules: snd_hda_intel

ALSA seems to detect this just fine. Relevant output of aplay -l:

nphuracm@nphuracm-Arle-A ~> aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 0: ALC887-VD Analog [ALC887-VD Analog]

card 0: Generic [HD-Audio Generic], device 1: ALC887-VD Digital [ALC887-VD Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Replugging the speakers does not work the issue around. The speakers work fine on another operating system so not a hardware issue (presumably).
First bunch of logs pulseaudio -v pours out:

Re: PulseAudio not detecting speakers at all

You probably broke your logind and dbus session configuring "xrdp shit". What exactly did you do and what happens if you revert that? Outputs of

printenv
loginctl session-status

?

Re: PulseAudio not detecting speakers at all

PULSE_SCRIPT=/etc/xrdp/pulse/default.pa

get rid of that export. Check/post

systemctl --user status pulseaudio
systemctl --user cat pulseaudio
