PMDG B744 Turbine sound studio's

I have just downloaded this sound file for the Rolls Royce engines for the B747, and I have the following problems.First of all there is a lot of crackle in the background like an annoying ticking which i cant get rid of. Second, My Saitek Throttle quadrant wont work when I use the TSS sounds. When I revert to another aircraft that doesnt use these sounds the quadrant is fine. I have to use the F2 F3 F4 commands to control the throttle.I am flying the PMDG B744 for FS9.Can anybody help please?, many thanks,Best Regards,Chris EGBB
