Updated to Ubuntu 22.10 and Pipewire detects no audio device

[Ardeshir]

I just updated to Ubuntu 22.10 a few days ago, apparently, it comes automatically with Pipewire as the audio server. But it detects no audio device on my laptop (neither input nor output).

My laptop is "Dell Latitude 3520", and I have "Ubuntu Kinetic Kudu (development branch) 64-bit" on Wayland (and GNOME 42.3 if it is useful information as well)

When I run "apt list | grep pipewire" I see this output:

```
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

This is the output of lsb_release -rd:

```
Description: Ubuntu Kinetic Kudu (development branch)
Release: 22.10
```

I saw similar bug reports and discussions on the internet, with some workarounds and ways to try to see if they fix this, but I decided to report it just to mention automatic upgrade to 22.10 breaks audio devices by default in some cases. If I did something and fixed it, I will write here.

Adding an empty file helped me: /usr/share/pipewire/media-session.d/with-pulseaudio and fixed the issue.

Does installing `wireplumber` resolve the issue?

[Ardeshir (ardeshireo)]

@patrickmcevoy thank you for the follow-up.

The answer is Yes!

I removed the `/usr/share/pipewire/media-session.d/with-pulseaudio` file I already created, and rebooted, and the problem appeared again: no audio devices.

I did `sudo apt install wireplumber` and rebooted, the problem was solved, I have my audio devices, the playback and recording works fine as well.
