I was getting background static/loss of quality in many of the engine sounds, and serious popping and crackling in others. In addition, levels were weird with guns sounding quiet in comparison to engines. I opened up the sound settings from within Il-2 and turned down master volume and objects volume to somewhat less than half and turned up voices volume to max (I always have music off). I have to have my speakers at a higher volume level than normal, but all the distortion is gone and engine volume sounds more normal. 50 cals still sound weird to me, but that may be a specific bug as mentioned. I'm not enamored with all the sounds, but they certainly don't sound bad.

I have noticed the same thing. The problem is due to the sound files being saved in formats that the Il-2 game is not designed to use. It is a common issue among people who produce these sound mods. Few seem to understand the limitations and save their samples in any old format. The cracks, pops and shrieks are the tortured screams of a game engine designed to play 11000mhz mono sound samples, as it struggles to play large wav files saved in stereo, or audio frequencies way over it's maximum.
