Hello everyone, I found myself in a need to connect my Lenovo T460p

over HDMI to a TV and I have no sound going over HDMI.
I saw a thread about 4 months ago with no solution found back then.
I'm on Fedora 29 KDE, kernel 4.20.13-200.fc29.x86_64. I don't see that
HDMI audio device becomes active neither via cli, no in gui. Video output
works perfectly fine. I'm using bumblebee with nvidia proprietary drivers,
not sure if that's relevant; aplay -l shows that HDMI is handled by
intel's graphics:

Found these two BZs [0][1] which kind of indicates it's been broken since

Any ideas what can be done here?
usually when I connect an hdmi cable I need to killall pulseaudio, then it
will work via pavucontrol, although typically kde sound control still may
not show it.
