Pipewire virtual devices as systemd user services

README.md

Create pipewire virtual devices as systemd user services

Add both files to ~/.config/systemd/user/ and enable them via systemctl --user enable --now pipewire-source-stereo@sourcename.service or systemctl --user enable --now pipewire-sink-stereo@sinkname.service. Change sourcename and sinkname in the command to your needs. You can add multiple devices with different names.

pipewire-sink-stereo@.service

[Unit]
Description = Add a pipewire stereo sink named %i

After = pipewire.service

[Service]

StandardOutput = journal

ExecStart = /bin/sh -c 'pactl load-module module-null-sink media.class=Audio/Sink sink_name="%i" channel_map=stereo > %h/.cache/pipewire_sink_stereo_%i'
ExecStopPost = -/bin/sh -c 'pactl unload-module $(cat %h/.cache/pipewire_sink_stereo_%i)'
ExecStopPost = -/bin/rm %h/.cache/pipewire_sink_stereo_%i
