Hi Mattias,
The issue is that Server 2016 and 2019 doesn't run the audio service automatically. This is why you aren't getting any sounds. Most servers would never need this so they choose to leave it off. Starting this service will need some sighted assistance and then you can start Narrator. To start the service, go to Service via run by typing services.mmc then look for windows audio service. Then go to its properties and you will need to set it to automatic then hit the start button.
Hope this helps,
Billy
