Hi. I have many AC where I can only hear engines in the cockpit unless I pan around and face aft. I guess its trying to add realism but I depend on hearing the engines to monitor. Any ideas where I can find a way to disable this feature?

Common Solutions for FSX Engine Sound Issues:

• Disable Headphones Simulation: Go to Settings > Sound and ensure "Headphones Simulation" is turned off.
• DirectX 10 Preview: Toggle the "Preview DirectX 10" option in Settings > Display > Customize.
• Disable Audio Devices: Disable unused microphones or audio devices in Windows to stop input interference.
• Check sound.cfg: In the aircraft's sound.cfg file, ensure panning parameters are not set to only one channel (e.g., set to 0 for center).
• Check Speaker Setup: Ensure your Windows sound configuration matches your physical speakers (e.g., set to Stereo if using headphones, not 5.1/7.1).
• Reinstall/Update Sound Drivers: Ensure audio drivers are updated. 
   

If the sound works only in external views or changes when panning, it is usually a bug in how FSX handles stereo/surround sound in the cockpit view. 

 

ALSO:

To fix FSX sound issues where audio fades, cuts out, or becomes quiet during ATC communication, set Windows to "Do Nothing" in the Sound Control Panel's Communications tab. This prevents Windows from lowering FSX volume when it mistakenly detects voice activity, a common issue with Windows 10/11 updates. 

Steps to Fix FSX Sound (Do Nothing):

1. Open Control Panel: Right-click the speaker icon in the taskbar and select Sounds or Sound Control Panel.
2. Communications Tab: Click the Communications tab.
3. Select "Do Nothing": Under "When Windows detects communications activity," choose the "Do nothing" option.
4. Apply Settings: Click Apply and then OK.
5. Disable Exclusive Mode (Optional but Recommended): In the same Sound dialog, go to the Playback tab, right-click your active speaker/headset, select Properties, go to the Advanced tab, and uncheck "Allow applications to take exclusive control of this device". 

This issue occurs because Windows treats FSX engine noises as communication sounds, often reducing the master volume by 80%. 

I did all that. I think it has to do with this section...which I couldnt figure out.

Hi. Clearly it seems to be affecting multiple aircraft so have you installed anything that might have modified some of the FSX cockpit sound parameters?

some planes do it and some planes dont...i think its in the Individual plane's settings...majestic q400 actually has a feature where you can toggle this on and off...i wonder how they do it?....what file is getting modified

Although I own the Majestic Q400, I have the Pilot version and not the Pro version which is the one with the toggle sound feature you mention so it is not something I have come across. However one way to possibly identify what file is getting modified would be to copy your Majestic Q400 sound.cfg file then apply the feature that you mention and make a copy of the sound.cfg after it has been applied. You could then compare the two cfgs and see what parameters, if any, have changed. This might give you some clue as to which parameters you might need to play about with to rectify the issue but I am not experienced enough with sound files to say what you should do so I certainly can't advise you on this! Maybe someone with more knowledge of FSX sound physics who might read this thread could advise you on that.

The one bit of advice that I would give you is to ALWAYS make sure you keep a backup copy of any files you modify so that you can easily restore them if everything goes belly up!
