pa-dlna v0.10

pa-dlna test coverage

pa-dlna forwards audio streams to DLNA devices.

A Python project based on asyncio, that uses ctypes to interface with the libpulse library and supports the PulseAudio and PipeWire [1] sound servers.

pa-dlna is composed of the following components:

  • The pa-dlna program forwards PulseAudio streams to DLNA devices.

  • The upnp-cmd is an interactive command line tool for introspection and control of UPnP devices [2].

  • The UPnP Python package is used by both commands.

  • The libpulse Python package is a ctypes interface to the libpulse library.

See the pa-dlna documentation.


Python version 3.8 or more recent.


The built-in UPnP package and therefore the upnp-cmd and pa-dlna commands depend on the psutil Python package. This package is available in most distributions as python3-psutil or python-psutil. It can also be installed with pip.


pa-dlna uses the pulseaudio parec program [3]. Depending on the linux distribution it may be already installed as a dependency of pulseaudio or of pipewire-pulse. If not, then the package that owns parec must be installed. On archlinux the package name is libpulse, on debian it is pulseaudio-utils.


No other dependency is required by pa-dlna when the DLNA devices support raw PCM L16 (RFC 2586) [4].

Optionally, encoders compatible with the audio mime types supported by the devices may be used. pa-dlna currently supports the ffmpeg (mp3, wav, aiff, flac, opus, vorbis, aac), the flac and the lame (mp3) encoders. The list of supported encoders, whether they are available on this host and their options, is printed by the command that prints the default configuration:

$ pa-dlna --dump-default


Optionally, one may install the pavucontrol package for easier management of associations between sound sources and DLNA devices.


pipewire as a pulseaudio sound server

The pipsewire, pipewire-pulse and wireplumber packages must be installed and the corresponding programs started. If you are switching from pulseaudio, make sure to remove /etc/pulse/client.conf or to comment out the setting of default-server in this file as pulseaudio and pipewire do not use the same unix socket path name.

The parec ‘s package includes the pactl program. One may check that the installation of pipewire as a pulseaudio sound server is successfull by running the command:

$ pactl info


Install pa-dlna with pip:

$ python -m pip install pa-dlna


A pa-dlna.conf user configuration file overriding the default configuration may be used to:

  • Change the preferred encoders ordered list used to select an encoder.

  • Configure encoder options.

  • Set an encoder for a given device and configure the options for this device.

  • Configure the sample_format, rate and channels parameters of the parec program used to forward PulseAudio streams, for a specific device, for an encoder type or for all devices.

See the configuration section of the pa-dlna documentation.
