# Running the WirePlumber Daemon

## Configure PipeWire

PipeWire 0.3 comes with an example session manager that you will need
to disable and replace with WirePlumber. This can be achieved by editing
`src/daemon/pipewire.conf.in` in the PipeWire git tree or
`/etc/pipewire/pipewire.conf` in an existing installation:

```
diff --git a/src/daemon/pipewire.conf.in b/src/daemon/pipewire.conf.in
index cebded96..dee1743b 100644
--- a/src/daemon/pipewire.conf.in
+++ b/src/daemon/pipewire.conf.in

     # Start the session manager. Run the session manager with -h for
     # options.

+    "wireplumber" = {}
     #
     # You can optionally start the pulseaudio-server here as well
     # but it better to start it as a systemd service.
```

This setup assumes that WirePlumber is *installed* on the target system.

## Run independently or without installing

If you wish to debug WirePlumber, it may be useful to run it separately from
PipeWire or run it directly from the source tree without installing.
To do so:

1. Comment out with `#` the `"wireplumber" = {}` line from `pipewire.conf`
2. Run pipewire:
  - if it is installed, execute `pipewire`
  - if it is **not** installed, execute `make run` in the **pipewire** source tree
3. Without stopping pipewire, run wireplumber:
  - if it is installed, execute `wireplumber`
  - if it is **not** installed, execute `make run` in the **wireplumber** source tree
