Dear Roon community
Perhaps I can help a Roon user with this. I have found the solution to my problem, and it is actually very simple. After measurements with LatencyMon show that the latencies are lower when the MSI GeForce graphics card is deactivated, only the Microsoft Remote Display Adapter graphics card is activated in audio mode. However, Roon could only be opened after a restart. Then it was no longer possible. The solution is to end the RAATServer, Roon, RoonAppliance and RoonServer processes with Task via the Task Manager and then open Roon again using the button without a restart being necessary.
