Sound Slider Settings?

What slider settings are you using to fine-tune the sounds for your PMDG 737-800? Or, are you using add-on sounds for the aircraft? The reason I ask is that I just have a feeling that the "mix" I have just doesn't seem to sound quite right - too much extraneous noise and not enough aircraft (yes I know the engine sound is muted somewhat in the cockpit in real life). BTW, I do have a high end card and high end speakers.My settings: Engine 91, Cockpit 55, Environment 5, Navigation 25, Lessons 50, ATC 95.Thanks!
