PipeWire is a service that facilitates sharing of multimedia content between devices and applications.

On startup, the daemon reads a configuration file to configure itself. It executes a series of commands listed in the config file.

The config file in the default location is used but the environment variables PIPEWIRE_CONFIG_DIR, PIPEWIRE_CONFIG_PREFIX and PIPEWIRE_CONFIG_NAME can be used to specify an alternative config directory, subdirectory and file respectively.
