Today, we will be seeing how to restore the audio outputs after upgrading an Ubuntu Cinnamon Remix 22.04 to Ubuntu Cinnamon Remix 22.10.
I had this problem happen on my machines after installing Ubuntu Cinnamon Remix 22.04 and then performing an upgrade using the command
do-release-upgrade -d. This effectively upgrades Ubuntu 22.04 to the latest development version which currently is 22.10. However, it seems it messed up with my audio. Luckily, the solution is simple and we will see the steps below.
After upgrading Ubuntu to the development version 22.10, your audio cards disappear from the audio settings, only showing a “Dummy Output” card:
This seems to happen because one of the changes that Ubuntu 22.10 will have is that they will stop using PulseAudio in favor of using PipeWire entirely. PipeWire is backward-compatible with ALSA, PulseAudio and other audio rendering software. Hence, it makes sense for Ubuntu to make full use of PipeWire.
The issue seems to be that the upgrade path that is used to upgrade to Ubuntu 22.10 may be missing a package to make the audio work correctly. In the meantime, we can enable back our audio devices with a simple package installation.
The solution is simple. We must install the
wireplumber package. This will replace the
pipewire-media-session package and your cards will be restored after installing it and rebooting your machine.
First, we install
wireplumber in the terminal using
sudo apt install wireplumber
We then approve the install pressing the Y key.
wireplumber will get installed:
Reboot your machine and enjoy having your sound restored:
