White Noise when I start Musescore 3

Hi everybody, hope your doing good. The second or the third time I start Musescore since the installation on my new laptop (ask me the infos you need of it) , it reproduces a loud white noise instead of reproducing the notes.. but not only the notes in musescore: also the other sounds of the laptop turn into a white noise(device sounds, notifications, mp3 player, youtube...). This keeps going on until I close the program and I reboot the laptop.. so Musescore for me is unusable. Hope you can help me with this. Bye!
