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.
This script is intended to automatically fix the sequence numbers for all tables in the current database.
This is accomplished through the use of the setval()
command, which we provide with the next ID value we wish to make use of.
We use the setval(sequence, number, is_called)
overload
and set is_called = false
in conjunction with COALESCE(MAX + 1, 1)
to ensure that, with an empty table, the next sequence
value is 1
as expected.
