I can’t sort it out.
When I start YouTube VM with Trivalent I have no sound in browser.
Sound is available in MPV but not in Trivalent.
When I close Trivalen and run Firefox then sound is present in Firefox.
Then when I close Firefox and run Trivalent then sound is working.
???
Any ideas?
It seems that Trivalent because is hardened don’t activate pipewire-pulse session.
solution: run pactl info or firefox before trivalent
make pactl-info.desktop file in ~/.config/autostart/ in affected VM
