In order to find a solution I "ran as admistrator" fldigi, checked Portaudio and flrig, "saved config" in the top menu and it works: after closing fldigi it restarts with Portaudio checked. If I start it as normal user Portaudio is not checked. I'm quite surprised but I found a solution to my problem even if this problem is faced by nobody else!
