Fake "OS doesn't allow mic usage"?

Hi everyone , I just installed teamspeak on my computer under windows server 2019.
According to it, I didn’t activate mic usage innOS settonfd. However when I go into mic settings , it’s activated.
Furthermore , when I use discord for example I don’t have any problem . Last but not least , Hen I use teamspeak portable version , mic usage is also normal…^^

Anyone got an idea ?

Best regards

Maybe some .dll file is blocked. If thats the case you can unblock them by right click on the .dll file -> properties and then there should be a allow button or something similar to it.
