Partial sound in media players Ubuntu 22.04.1 LTS

Problem: When watching movie on VLC or other media player, there is only a partial sound - background sounds only, but there is a lack of sound of dialogues. I can't hear conversations. When playing YT or Spotify in the browser (chrome/firefox), the whole sound can be heard very well.

I'm using Ubuntu 22.04.1 LTS (installed from bootable usb) with 5.15.0-52-generic kernel.

SMBIOS 3.3.0 present.

Any ideas how to fix this?

Take a look in Settings...Sound... and see which one is chosen.

Mine only works properly when I have the Line Out Family 17H one chosen.

I also have had some odd experience with the FireFox web browser & my sound when playing videos -- I would hear crackling popping & the sound level would be low. When I would switch to a different browser it would work.

Oh, also, are you running Wayland windowing system? Or area you running X11? I've seen a number of problems with Wayland and when I switched away (to X11) on 22.04 I didn't have any problems after.

Checking Settings...About... Windowing System

Here's how you can change it if you want to : Use X11 instead of Wayland.
