Hello all,
I noticed some of you guys, including me, have found the packs to be very loud. An easy way to temperarly adjust this to your liking, while IXEG fixes/ adjusts the sounds, is to get a program that can adjust db's (decibels) of audio (I use audacity) and lower the sound to your preference. Go to your IXEG aircraft folder, sounds, custom, and aircond_noise.wav. This is the file you want to manipulate. Once you lower it to your liking, put it back in the custom sound folder, and replace the old one. (I'd recommend making a backup of your old aircond_noise.wav file just incase)
I personally lowered it about 15 decibels and I find it sounds much better. I can hear the knobs and engines at cruise and full power.
Hope this helps!
Happy landings!
