In an attempt to make FS2004 run without crashing due to the clogged installation on my Windows 7 Professional drive, I bought a copy of Windows 7 Home Premium and put that on a separate hard disk. Having installed Windows 7 SP1 and all the necessary updates, MB chipset, sound and video drivers, I did a clean install of FS2004. Installed SP1 and booted it up.
Everything is great, except the voices - both pilot and ATC have some background distortion, like there's interference on the radio.
All other sounds are OK. I checked my audio drivers etc. All drivers are same as what I was using on the Windows 7 Professional installation. I've uninstalled and reinstalled several times, but the problem remains. I'm totally clueless as to why this should be happening, as aside from being a different Windows installation on a different hard disk, the installations are identical.
If anyone has come across this situation before, or has any useful suggestions, then I would be extremely grateful as this so frustrating.
Cheers
Tony
