F32, nVidia, & hdmi audio problem

[Jack Craig]

Hello fedora users out there in fedora land

I have a problem with hdmi audio on fedora 32 with an Nvidia card.

I recently had to replace my desktop workstation,  it is now built upon
HP elite desktop, Nvidia card on fedora 32 .

After install, audio over HDMI on the video card was OK, but after using it
for a short while, the audio over hdmi stopped working.

the sound config now directs all hdmi audio to the installed
internal speakers rather than out the hdmi port.

suggestions? thx, jackc...

I'm on F31, kde.  In 'System Settings' I have a virtual device giving 
simultaneous audio output to inbuilt audio and HDMI.  The virtual device 
is the ALSA default, and the speaker widget controls the two volume 
settings independently.

I have kde-settings-pulseaudio installed too, and I believe in 'buntu 
paprefs is relevant.

no, i was able to create the dual output, but F32 directed that to the
internal speakers.

i disabled audio in bios, in sound config, i see meter lite, but no audio
output, and am at ...

cat /proc/asound/cards

I unfortunately have a laptop with NVidia graphics and I had to install 
the proprietary drivers because of strange behaviour.  The HDMI audio 
does not work properly either.  It lags and gets very noisy.
