Disable pushback truck sounds?

[ajpongress]

Hi,

I want to disable the engine sounds from the pushback trucks.
I found the sound files in the gsx folder and renamed them with BACKUP at the end, but I still get the sounds in the sim.
I even got an empty sound file, copied it and named it after every sound file that had an engine sound. Still heard the sounds in the sim.

The gsx options within FSX only let me change the sound volume for everything.

How do I disable the vehicle engine sounds?
Thanks.

Some vehicles use some sounds from the default FSX sounds folder, the Pushback engine sound is taken from the FSX\soundai\Fueltruck folder.

Thanks! I'll give that a try.
