nextcloud-talk-desktop: Audio device selection broken

[Nivalux]

Nixpkgs version

• Stable (25.11)

Describe the bug

Hi,
I just tried out the talk desktop client and it worked fine, aside from one issue.
In the "Device test" window I cannot select another output device at all.
For the Audio Input device, it shows all devices, but if I select anything but the default one the test button bellow grays out.

I then tried out the package from the unstable branch via nix run nixpkgs-unstable#nextcloud-talk-desktop, but that didn't change the listed devices or behaviour when selecting one.

After that I downloaded the official flatpak and ran that and there the output and input audio device selection worked. Interestingly the listed audio input devices looked very different between the native and the flatpak version.

Does it work for anyone else?
Not sure, if this is a case of a missing dependency, a permission issue or something else entirely.

Steps to reproduce

Install the nextcloud-talk-desktop, login, open the "Device test" window and check the audio device options.

Expected behaviour

See the available audio devices listed for input and output. After selecting them, have them work and the test function available.
