# Enable PipeWire on Ubuntu 22.04

> *This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like `pipewire-debian`, you might get into conflicts.*

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Unfortunately, aptX and AAC are not enabled because of patents and other technical reasons. However, looks like aptX will be available in coming 22.10 release. If you need these codecs in 22.04 you may use [this PPA](https://launchpad.net/~aglasgall/+archive/ubuntu/pipewire-extra-bt-codecs) from @aglasgall which is based on `universe`, but rebuilds `pipewire` with additional packages for aptX and AAC from `multiverse`. Read the discussion [here](https://gist.github.com/the-spyke/2de98b22ff4f978ebf0650c90e82027e?permalink_comment_id=4320194#gistcomment-4320194).

Based on [Debian Wiki](https://wiki.debian.org/PipeWire#Using_as_a_substitute_for_PulseAudio.2FJACK.2FALSA), but simplified for Ubuntu 22.04.

## Install

Install codecs for LDAC (SBC is included out of the box):

```sh
$ sudo apt install libldacbt-{abr,enc}2
```

Install remaining PipeWire packages and WirePlumber as the session manager:

```sh
$ sudo apt install \
  libspa-0.2-bluetooth \
  pipewire-audio-client-libraries \
  pipewire-media-session- \
  wireplumber
```

> *Notice '-' at the end of 'pipewire-media-session'. This is to remove it in the same command, because 'wireplumber' will be used instead.*

Start WirePlumber for your user:

```sh
$ systemctl --user --now enable wireplumber.service
```

## Configure

### ALSA

Single step. Copy the config file from the PipeWire examples into your ALSA configuration directory:

```sh
$ sudo cp /usr/share/doc/pipewire/examples/alsa.conf.d/99-pipewire-default.conf /etc/alsa/conf.d/
```

### PulseAudio

Everything was done automatically by `pipewire-pulse` package, which should have been installed by `wireplumber` package as recommended. If not, install it yourself.

### Bluetooth

Just remove this package and Bluetooth will be handled by PipeWire:

```sh
$ sudo apt remove pulseaudio-module-bluetooth
```

## Done

Reboot and check if it works by running:

```sh
$ LANG=C pactl info | grep '^Server Name'
```
