Under Options>Settings>Sound>Engines the engine volume slider has no effect on the sound volume of the engines, nor does removing the check mark by engines, or pressing Q to totally turn off sound in FS9. The engine sounds remain the same regardless of these settings. There are some other third party planes I have noticed this with as well. Anybody know a way to control it?Thanks:RTH

In an earlier thread on this ac someone mentioned that it gets it's sound through Directx so as to improve frame rates..I have no idea how to control it..JamesJ

In the Dash8_Q300_2 folder, there is a folder named "ini" . In this folder is a file, open it and change SOUND_VOLUME=210---- default is 255. This adjust the engine sound volume. Below 200 is kind of distorted on my system, try different numbers with your sound system. Farmer

Thanks Farmer:That will help much. On VatSim it is a little hard to communicate with so much engine noise.RTH
