Enable PipeWire on Ubuntu 22.04

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.

Rust error handling is nice but obligatory. Which makes it sometimes plenty of code.

Result is defined as Ok or Err. The definition is generic, and both alternatives have

Gulp + browserify + babelify + react

Use React with Gulp, Browserify and Babelify. This allows you to use React in jsx & node.js style. It let's you use require('module') in your JavaScript. Babelify will transform the jsx code to JavaScript code.

Development

gulp build-react

This will generate a main.min.js file in the build directory with sourcemaps.
