The instructions below have not been thoroughly tested and make break things.
PipeWire is a multimedia processing engine that aims to improve audio and video handling on Linux.
Add your normal user to the
audio group. The user must log in for this to take effect.
# addgroup audio <user>
PipeWire requires a running D-Bus session. If you use a full desktop environment this will probably be started automatically, but with minimal window managers it must be done manually.
# apk add dbus dbus-openrc dbus-x11 # rc-service dbus start # rc-update add dbus default
dbus-launch whenever you start an X or Wayland session. For example:
$ dbus-launch --exit-with-session sway
Installation and configuration
pipewire. It might be a good idea to use the edge version because it's more up-to-date and PipeWire is still under development.
# apk add pipewire pipewire-doc
PipeWire can run a Pulseaudio daemon which should allow all existing Pulseaudio applications to be used with the PipeWire backend.
# apk add pipewire-pulse
To enable the Pulseaudio daemon edit
/etc/pipewire/pipewire.conf and uncomment the following line:
If you will be using PipeWire for Jack applications install the required package and make system wide links to the PipeWire replacement Jack libraries (I have not had success using
pw-jack). You will not need to start a Jack server.
# apk add pipewire-jack # ln -sf /usr/lib/pipewire-0.3/jack/libjackserver.so.0 /usr/lib/libjackserver.so.0 # ln -sf /usr/lib/pipewire-0.3/jack/libjacknet.so.0 /usr/lib/libjacknet.so.0 # ln -sf /usr/lib/pipewire-0.3/jack/libjack.so.0 /usr/lib/libjack.so.0
Video should work out-of-the-box with v4l2 devices (e.g. a lot of webcams) and GStreamer applications.
Screen sharing on Wayland
Not got this working yet. Take a look at xdg-desktop-portal.
Start the PipeWire media server. You'll probably get quite a few errors but just ignore them for now.
In a different terminal window check the default output device. I don't yet know how this default can be changed for all applications, so you'd better hope it's right!
$ pw-cat -p --list-targets
Test sound is working using an audio file in a format supported by libsndfile (e.g. flac, opus, ogg, wav).
$ pw-cat -p test.flac
If you have a microphone test recording audio is working.
$ pw-cat -r --list-targets $ pw-cat -r recording.flac (Speak for a while then stop it with Ctrl+c) $ pw-cat -p recording.flac
Test Pulseaudio clients using a media player (most use Pulseaudio) and if you use Jack test that too:
# apk add jack-example-clients $ jack_simple_client
You should hear a sustained beep.
If you are happy everything is working, make pipewire start automatically when your X or Wayland session starts. For example, you could add the
pipewire command to
~/.xinitrc or your window manager's config file.
