This happens in both Tumbleweed & Garuda Linux. On tumbleweed, I installed Zoom via flatpak, AUR on Garuda; no errot or anything when I try to share audio, just doesn’t do anything, shares the window fine. I use KDE on X11. About a year ago, I successfully shared sound on Tumbleweed
You could try running the flatpak with a few flags.
https://docs.flatpak.org/en/latest/sandbox-permissions-reference.html
--socket=pulseaudio is used to allow pulseaudio access but there is currently no --socket=pipewire flag
We can see here that the zoom flatpak is already built with that flag enabled.

**Hypothesis**
Detecting if wayland is enabled in a Flatpak is easy. We just ch… eck if we find the flag:
```
--socket=wayland
```
As far as I know there is no `--socket=pipewire`-flag. Correct me if I am wrong 🙏
As far as I can tell from looking through `.json|.yaml`-files, pipewire-support can be detected if we find the flag:
```
--filesystem=xdg-run/pipewire-0
```

**Questions**
- Is this the official way to enable the Pipwire-socket inside a Flatpak?
- @TheEvilSkeleton Can you confirm anything?
- Are there official documentation explaining this?
- Is there an equivalent to `--socket=fallback-x11` in the Pipewire world?
Seems like --filesystem=xdg-run/pipewire-0 is the way to enable pipewire
Try that perhaps.
