I think KDE is relying on a same pulseaudio layer (kde-settings-pulseaudio) for it's audio device management, hence I can see same set of devices (and same settings) as through the pavucontrol as I do in KDE Audio Settings and no display mentioned as an output device.

Hello, just a shot:
Fedora uses Pulseaudio as an audio layer. I have been experiencing minor issues with sound routing through various channels (I am using an external sound card for example) and I could solve everything by installing an application called pavucontrol and use that to do the sound settings. Have you tried that?

 Hello everyone, I want to re-visit the question that I've raised a year ago here [0]. I'm still running my Lenovo T460p, but we're already in F32 and still same issue presents.
 I've just recently got a new Dell monitor that I connect for the lack of USB-C ports over DP and in KDE environments, there is no visible ways to route sound over DP as far as I can tell. I've also tried booting Manjaro KDE and it seems to be missing component in KDE itself?
 Other distros (Fedora Gnome, Ubuntu, Linux Mint, Elementary) even live image recognize DP as an output and can successfully route sound there.
 What would be the action plan here? Did anyone look into that already maybe? I'm wondering where the problems lies or what part/component is missing?
