Have a strange minor problem with the default Cessna 172 soung. Before just a while ago you could always hear the plane running at idle when it was first loaded. Now you can't hear anything but a very slight kind of frying noice, until you give it throttle then it sound like before. I had to turn the aircraft sound way up just to get the frying noice. The only change I've made is loading the ALPHA Pensacola @ CVN69 scenery, and the N3N floatplane.
From the exterior the plane sounds as always ,it's just from the cockpit that you can't hear the engine running.
As far I could check the other planes are ok with the engine sound at idle ,the only plane seems to be the default Cessna.
It seems something happened to the sound config for the interior. If you shut down the engine , and restart the engines makes the shutdown sound and startup but as soon as it settles to idle it get very quiet.
I replaced the sound file,(but backed it up) with the sound file from the Realair Cessna 172 and now it's fine,so I'am guessing somthing happened to the sound config file.
Any ideas on what might have happened?
