Description Alexey Skobkin 2021-10-30 18:59:34 UTC

After upgrading from 0.3.38 pipewire stopped showing all sound devices.
I've checked if the media session daemon is running and it wasn't.
Checking the unit showed following:

> $ systemctl --user status pipewire-media-session.service
> Unit pipewire-media-session.service could not be found.

Then I've checked the path where unit was before update:

> > $ ls -la /usr/lib/systemd/user/pipewire*
> .rw-r--r-- 1.2k root 29 Oct 13:22 /usr/lib/systemd/user/pipewire-pulse.service
> .rw-r--r--  172 root 20 Oct 18:00 /usr/lib/systemd/user/pipewire-pulse.socket
> .rw-r--r-- 1.0k root 29 Oct 13:22 /usr/lib/systemd/user/pipewire.service
> .rw-r--r--  120 root 20 Oct 18:00 /usr/lib/systemd/user/pipewire.socket

For me it looks like the unit file is missing.

Falling back to the previous version solves the issue:

> # emerge -a1kvqt \=pipewire-0.3.38

> $ systemctl --user daemon-reload

> $ systemctl --user status pipewire-media-session.service

Reproducible: Always

Upstream are no longer supporting media-session really. Read the postinst -- you need to use WirePlumber instead.

I don't think we have an interest in packaging media-session separately at this point in time given its rapid deprecation.
