[Landry MINOZA]

Package: libpipewire-0.3-modules
Version: 0.3.65-2
Severity: normal

Dear Maintainer,

Trying to use remote devices with pipewire, I don't see some devices
(specificaly a headset mic in my case).
Reproduce on 2 sid clients.

I load zeroconf module:

pactl load-module module-zeroconf-discover

When listing available devices:
