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.

There are many top conferences for fields attacking big problems. There problems remain unsolved for a long time. Still many papers have been accepted.

What are these papers?
How to keep publishing in a field attacking a grand challenge, while not really a solution is found?

You raise an interesting point about the nature of research and publishing in fields tackling grand challenges. Here's a breakdown of the types of papers that get published in these areas and strategies for continuing to contribute:
