Fedora KDE and sound over HDMI/DP

[Alex Gurenko]

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?

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?*

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.

Not sure if this may be related, but in my laptop (LG Gram) I had to
set "load-module module-alsa-source device=hw:0,0" in
/etc/pulse/default.pa to make the mic work. No issues with the output
though, either with HDMI in particular. And I don't have pavucontrol,
just plasma-pa and kde-pulseaudio-settings.
