Hello, I am running Window 7 Professional and am having an issue with engine sounds in Flight Simulator 2004. When loading the default aircraft which is a Cessna 172, all sounds including engines are working properly. However when I choose any other aircraft, no engine sounds are present. I have tried multiple re-installations to no avail. All sliders are where they should be in the settings. Oddly enough, I also run FSX, and all sounds on all aircraft work properly including engines. Thank you.

Make sure you sound card has "Audio effects" and "CMSS 3D Surround sound" turned off. For FS2004 only the basic setting works.
See if this does the job.
