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.

TODO - hack the kindle paperwhite

focus on the gen 2 / DP75SDI

compile kernel + initramfs with openwrt:

• because it cross-compiles easily
• has a reasonably simple user-space
• device-tree?

#!/usr/bin/awk -f
#!/usr/bin/awk -E
#
# If you have an awk version that doesn't support the -f flag,
# then you are just out of luck.
#
# If you just have no clue where awk will be, or you prefer to use -E,
# then you can try this bash snippet to launch awk for you.
#
# You might think the -E tests below are overly complex. You'd be wrong.

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

Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.

Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - se

# Uncommited Changes - Exit script if there uncommited changes
