My plane wont have any sounds or power, I tested other planes after installing the ixeg 3 times and they all have normal sounds, whats the problem? I noticed when I have the ixeg 737 active my xplane sound settings are turned off, external / internal and environment are off, when I switch to another plane then they all have normal sounds, can anyone please help? also i selected ground power on the menu and is not on the overhead available, again 3 times installed and same thing...
