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.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

Disabling IPv6

Source: https://www.leowkahman.com/2016/03/19/disable-ipv6-raspberry-raspbian/

Firstly, check for presence of IPv6 using ifconfig. You should be seeing a few lines containing inet6 addr: ....

To disable, edit a file: sudo nano /etc/sysctl.conf

Add the following line:

net.ipv6.conf.all.disable_ipv6 = 1
