How do I adjust exterior aircraft sound volume in FSX?

In FSX and FSX: Steam Edition, open Options > Settings > Sound and adjust Engines while using Spot view. That slider changes engine audio inside and outside the aircraft; FSX has no global exterior-only volume control. For independent outside volume, edit or replace that aircraft’s external sound configuration after making a backup.

How do I change exterior volume with the FSX sound sliders?

The Engines slider is the main FSX sound control for aircraft engine volume, including sound heard from exterior views.

1. Load the aircraft and start its engines. Use a steady throttle setting so the comparison is repeatable.
2. Switch to an exterior view. Spot or Locked Spot is more useful than a distant Tower view.
3. Open the sound menu. Press Alt if the menu bar is hidden, then choose Options > Settings > Sound.
4. Move Engines left or right. Lower it for quieter engine audio or raise it for louder audio.
5. Retest from the same viewpoint. Engine power and listener position both affect the result. A close visual zoom does not necessarily place the listener closer to the aircraft.

The Environment slider may alter what you hear outside, but it is not an exterior-engine control. Our breakdown of the FSX mixer controls explains how to balance engine, cockpit, environmental and ATC audio.

Can FSX change only the outside aircraft sound?

No standard FSX slider changes exterior engine volume without also affecting engine sound in the cockpit.

In the standard sound system, an aircraft’s sound.cfg separates internal and external samples. Sections using viewpoint=1 are intended for the cockpit, while viewpoint=2 identifies exterior sounds. External sample names often begin with x, but that is only a naming convention; the configuration entry is what matters.

1. Back up the complete sound folder. It is normally under SimObjects\\Airplanes\\<aircraft folder>\\sound. Boxed FSX and Steam Edition use different installation locations, so first find the aircraft folder used by your FSX installation.
2. Check for an alias. A configuration containing alias= obtains its sounds from another aircraft. Editing that shared source may change several aeroplanes.
3. Identify the exterior sections. Work only with entries assigned to viewpoint=2. The associated vparams define how volume changes through the operating range; they are not a simple master-volume value.
4. Make one small change at a time. Another option is to adjust the gain of copied exterior WAV files while preserving their filenames and original audio format. Excessive gain can cause clipping and distortion.
5. Reload the aircraft. Select another aircraft and return to the original, or restart FSX, before deciding that the edit failed.

We recommend a properly configured replacement sound set when you do not understand the existing response curves. Our guide to installing replacement FSX engine sounds safely covers aliases, backups and folder structure.

Why is one add-on aircraft still too loud or too quiet?

If only one aircraft has the wrong exterior volume, its own sound package is the likely cause rather than the global FSX mixer.

• Several aircraft change together: they probably share an aliased sound folder.
• The Engines slider has little effect: a complex add-on may generate some audio through gauges or modules and provide its own sound control.
• Only one engine phase is wrong: the relevant idle, combustion, propeller or turbine section may have an uneven volume response. Do not alter every external entry.
• Spot and Tower views differ sharply: this is usually distance attenuation. Compare them only when the listener is similarly positioned.
• The edit has no effect: check that you changed the active aircraft variation and not an unused duplicate installation.

Why can’t I hear MyTraffic or other AI aircraft?

If MyTraffic aircraft are visible but silent — “nie słychać” — first separate an FSX-wide mute from a missing or broken AI sound set. The FSX mixer has no dedicated MyTraffic volume slider.

• Your aircraft and all AI traffic are silent: check the global sound toggle, the FSX sliders and Windows output routing.
• Your own engine works but every AI aircraft is silent: raise the Engines slider, then check the traffic aircraft’s AI sound source. FSX AI variants can use a soundai selection or folder rather than the normal flyable-aircraft sound folder.
• Only certain MyTraffic models are silent: those models may have a missing sound folder, an invalid alias or an alias pointing to an aircraft that is not installed.
• Traffic is audible only at close range: that is usually normal attenuation. Tower views can place the listener far from the runway even when zoom makes the aircraft appear large.
• Aircraft engines are audible but ATC is not: raise the Voice control; ATC speech is not governed by Engines.

Do not start rewriting every traffic-aircraft configuration. Identify one affected model first and inspect the AI sound folder or alias it actually uses.

FSX has no sound at all: what should I check?

When all FSX sound is missing, restore global audio before changing any aircraft files.

1. Press Q once. This toggles FSX sound on or off.
2. Check the FSX Sound page. Make sure sound is enabled and the required sliders are above zero.
3. Open the Windows volume mixer. Confirm FSX is not muted and is routed to the intended speakers or headset.
4. Restart FSX after changing audio devices. The simulator may continue using the output selected when it was launched.

If the simulator remains completely silent, follow our FSX and Steam Edition no-sound checks before editing sound.cfg.
