Tried firefox, brave, chromium, slimjet. Videos not loading from youtube, odysee, rumble.
Works perfectly with F39.

Update:
What a mess!
Related to pulseaudio. Videos are loading after removing it.
But, back to case one with No more SPDIF passthrough after upgrading to F40
__
2nd update, the day after:
For browsers to be able to play videos, one must execute those commands after boot:
systemctl --user restart pipewire
systemctl --user restart pulseaudio
systemctl --user restart wireplumber
