Bug 487382

When plugging in an HDMI cable that should also carry the sound output, it does not detect the sound sink like it did on KDE Plasma 5 afaik.

Then when manually selecting the output from "devices" and "sound" and the dropdown hamburger menu, I can get sound through HDMI.

Then plugging out the HDMI cable, I dont have any sound output anymore and it gives me "no input or output devices found" which is compeltely wrong as my laptop has internal speakers and internal mic.

Instead, when still plugged in and under sound sink output device I select "Analog stereo duplex" (which is my laptop speakers) and then plug the cable out, I get an OSD that it switched to internal audio and works.

Using Fedora 40, using pipewire.

This is pretty broken as:
- the sound devices are not displayed as different devices, but different modes/settings of the same device (I guess)
- when selecting a "mode" of a "device" which is then not available anymore, the sound sink is gone
- only when plugging the device with the selected mode in again, and selecting a different output mode (which is actually a device) then plugging out does not cause this error
- the separation between "internal" and "HDMI" output is completely unfriendly to nontechnical users
