SYMPTOMS
When you play Microsoft Flight Simulator 2002 or Microsoft Combat Flight Simulator 2, the sound volume may increase or become distorted (crackle) when you change the cockpit view.



CAUSE
This behavior can occur after you install Microsoft Train Simulator.



RESOLUTION
To resolve this issue, use one of the following methods.

Method 1: Reduce Hardware Sound Acceleration
To do this, follow these steps:
 * 1) Quit all programs that are running.
 * 2) Click Start, and then click Run.
 * 3) In the Open box, type dxdiag, and then click OK.

The DirectX Diagnostic Tool starts.
 * 1) Click the Sound tab, and then drag the Hardware Sound Acceleration Level slider to the No acceleration position.
 * 2) Click Exit, and then test the game for proper function.
 * 3) If the game runs correctly, attempt to increase the hardware sound acceleration level until it is at the highest level possible without corrupting sound quality in the game.
