SUMMARY
***
Recently I noticed that in Vivaldi I cannot hear (for more than a second) the audio of TED video (ted.com)
***


STEPS TO REPRODUCE
1. Open some ted video (ted.com) with Vivaldi
2. Try to activate the sound
3. You will head the sound only for a second: the sound auto-disable itself immediately

OBSERVED RESULT

No (stable) sound

EXPECTED RESULT

(Stable) Sound

For me, with the same Vivaldi version, when started in X11 mode (the same cmdline as yours), videos in TED and Twitter don't play at all.

The error message: "ERROR:extension_host.cc(429)] Received EventAck for extension jffbochibkahlbbmanpmndnhmeliecah for an unknown event".

It also happens in the latest Chrome.

When started in Wayland mode (add "--ozone-platform-hint=auto" to the cmdline), both work fine.

Google search says "jffbochibkahlbbmanpmndnhmeliecah" is the internal name for "Picture-in-Picture" in Vivaldi. So I guess this is a problem with picture-in-picture in XWayland.

Could you test if the wayland switch above fixes the problem?

Now (for me) it is solved!
