After installing the Nu Audio card with it's drivers I noticed there are a couple of processes running with HIGH integrity with FULL elevation.
 

 
Is there any reason why processes, "EVGA_NahimicAPISvc32.exe" and "EVGA_NahimicAPISvc64.exe" need to run with such high elevation privileges? It would be better/safer to have these processes running with LOW integrity with LIMITED elevation...

    Is there a specific email address for the development / support team I could contact regarding this?

    Already tried to contact EVGA support, hence one of the reasons for posting here. I will reattempt contact...

    Default for the priority is "Normal", so it's unclear why it's running as a higher priority.  I wonder if you have a program that manages QoS and it might be elevating the Nahimic software automatically. to help with gaming.
     
    Feel free to try setting the priority to normal or low to see if the stutter disappears.

    No, it is not being elevated because of another process. The executable(s) contain no manifest (which it should be using) and are instead opting to use ShellExecuteEx to restart itself with administrator user privileges.
     
    During installation the installer creates a runtime registry entry and uses the following command line arguments to run with Windows start-up:
     
    HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
     
    "C:\Program Files (x86)\EVGA\NU Audio Card\EVGA_NahimicAPI\x86\EVGA_NahimicAPISvc32.exe" /start all/silent
    "C:\Program Files (x86)\EVGA\NU Audio Card\EVGA_NahimicAPI\EVGA_NahimicAPISvc64.exe" /start all/silent
     
    An entry to Windows Task Scheduler also exists with the following arguments and oddly enough without any triggers to start it - why?
     
    "C:\Program Files (x86)\EVGA\NU Audio Card\EVGA_NahimicAPI\x86\EVGA_NahimicAPISvc32.exe" $(Arg0) $(Arg1) $(Arg2) $(Arg3) $(Arg4) $(Arg5) $(Arg6) $(Arg7)
    "C:\Program Files (x86)\EVGA\NU Audio Card\EVGA_NahimicAPI\EVGA_NahimicAPISvc64.exe" $(Arg0) $(Arg1) $(Arg2) $(Arg3) $(Arg4) $(Arg5) $(Arg6) $(Arg7)

    @Ted:
     
    Yes same issue which you have here described and other users have post also here.
     
     
    I found for me an solution.
     
    I look into the task scheduler (Aufgabenplanung) and i see 2 taks too with the same arguments "$(Arg0) $(Arg1) $(Arg2) $(Arg3) $(Arg4) $(Arg5) $(Arg6) $(Arg7)" and that the task can´t run. See picture "EVGA_Task_Scheduler_overview".
    There is an error message 0x41303.
     
    Looks like that this arguments are wrong ....
     
    So therefore i create two new task.
    - One for the EVGA_NahimicAPISvc64.exe
    - and a second one for the EVGA_NahimicAPISvc32.exe
     
    Most important is, to activate higher privileges. This is stopping the request from UAC. See Screenshot EVGA_new_task_1.JPG
    and
    to set the right  arguments "/start all/silent". See Screenshot EVGA_new_task_2.JPG
    and the 3.
    is to start task if user is the trigger. See Screenshot EVGA_new_task_3.JPG
    and 4.
    deactivate in task manager the autostart from registry. See Screenshot EVGA_new_task_4.JPG
     
    So after an reboot , both tasks are started without UAC prompt and  
    EVGA_NahimicAPISvc64.exe
    EVGA_NahimicAPISvc32.exe
    are automatically started.
     
     
    So maybe this workaround helps other too, until EVGA have fixed it in an newer sw version..
     
     Good luck ;-)

    Thanks for continuing to look into this.  I've forwarded this again to our Audio Team.

    As an update, I've been told this will be fixed when we've received Nahimic's updated driver.  Just waiting on that, currently.

    Are you able to provide details of the changes to come please?
     
    Ideally my preference would be to not have have any of these processes elevated at all...

    I don't have a change log at this time.  The latest information I have is that we are looking at an early Nov. release.  I don't have a more specific date than that, at the moment.
