This think a recent pipewire (3.38 I think) is required on the host, and I doubt that a 3.5 year old Ubuntu has it.

This think a recent pipewire (3.38 I think) is required

Yeah, I read that on the issue #3 . I didn't know if the issue here is related to that one.

I doubt that a 3.5 year old Ubuntu has it.

You're right, it wasn't installed. But I installed it manually on my machine. Shouldn't this version work?

$ pipewire --version
pipewire
Compiled with libpipewire 0.3.42
Linked with libpipewire 0.3.42

Is there others dependencies that I should have installed on my host? I didn't find any information about dependencies.
I think you could add this information on the flathub doc 🙂
