No audio when i try to share it

Good day
For a while I have had the problem that when I try to allocate my screen
I can’t transfer it with sound it’s always the same as soon as I put the hook in,
Do I get the error message → The device could not be activated. Please check the permissions by clicking on the lock symbol next to the address bar.
I’ve tried a lot but nothing helps (the checkmarks are also set at the lock so there shouldn’t be any problems).
My Main Browser is OperaGX But in other Browsers For Example Chrome it also doesnt work

Thanks a lot for your feedback. Do I understand correctly that sharing the screen without audio works fine but only when you tick the audio checkbox you get that message?
