By recording "/home/$USER" isn't your own user and outside from mumble client this dir doesn't exist even to copy or move the audio files from it.
Tested with debian and solus, both are the same with mumble flatpak.

Maybe others understand this, but could you rewrite this for better understanding?
Mumble records located inside a dir '/home/$USER' this isn't the same as your /home/$USER. Try mumble via flatpak, then you understand this issue.
So mumble via flatpak trys to save audio recordings in /home/$USER, which is not accessable by the flatpak?
Not exactly :-)

Above is the /home/sia created with mumble flatpak, below the correct home/sia. Hope that clear enough :)
Thx for the clarification.
Update: See below.
Strangely I can't see any difference between the normal mumble version and the flatpak here:
https://github.com/flathub/info.mumble.Mumble
that could cause this different behaviour.
Update:
Ok now I think I know the reason: this is intended behaviour by flatpak.
Flatpaks goal is to seperate applications as best as possible.
See also: https://docs.flatpak.org/en/latest/sandbox-permissions.html
To change this behaviour the Mumble build config for flatpak would need to include the line:
--filesystem=home # or some other options
to access the user鈥檚 home directory.
So all you can do is ask the mumble team to change it, but for now this is not a bug.
Great, this fixed it under solus ;)
sudo flatpak override info.mumble.Mumble --filesystem=home
I created an issue in the Mumble Flatpak repo in order for them to be aware of this.

sudo flatpak override info.mumble.Mumble --filesystem=home
Interesting, thought it would be necessary to rebuild it.
Good solution for others, a general change of this might be useful though, I created an issue for this: https://github.com/flathub/info.mumble.Mumble/issues/14
Also next time open an issue first in:
https://github.com/flathub/info.mumble.Mumble/issues
:wink:
@Krzmbrzl Oh, you were faster, what are we gone do now? :smile:
Maybe you could include some of my stuff into your report? :thinking:
Can you change the title of this, so that it is clear for others who might search for it?
Include "flatpak".
I'll close my issue as a duplicate of yours. You seem to have put a little more effort into creating the issue ;)
Yeah I can do that :+1:
