No engine sound in MSFS 2024? Fix audio sliders, output routing, aircraft state, add-on packages and dependencies with this ordered checklist.
If MSFS 2024 has no engine sound, first confirm the Engine and Master volume sliders are raised, then check Windows or console audio routing and reload the aircraft. If only one aircraft is silent, its sound package, dependency or add-on installation is usually at fault rather than the simulator’s global audio.
Match the symptom to the likely cause
The fastest diagnosis is to identify exactly which sounds are missing before changing settings or reinstalling anything.
| Symptom | Likely cause | First check |
|---|---|---|
| No sound anywhere | Master volume, application mute or wrong output device | System volume mixer and MSFS Master volume |
| ATC works but aircraft sounds do not | Separate communications output or Aircraft and Engine sliders | Main game output and sound sliders |
| Only one aircraft is silent | Missing, incompatible or damaged aircraft sound package | Test an included aircraft |
| Sound works outside but not in the cockpit | Cockpit attenuation, headset simulation or aircraft-specific mixing | Compare cockpit and external views |
| Engine instruments show no RPM or N1 | The engine has not started | Load a ready-to-fly state |
How to fix missing engine sound in MSFS 2024
Work through these checks in order, testing after each change so that the actual cause remains clear.
- Confirm that the engine is running. Load the aircraft in a ready-to-fly state and check RPM, propeller RPM or N1 rather than relying on animation alone. A propeller can windmill without combustion, while a starter may turn the engine without achieving light-off.
- Compare cockpit and external views. If engine audio exists outside but disappears inside, the sound system is working. The problem is then cockpit attenuation, headset simulation or that aircraft’s interior mix rather than a missing sound package.
- Check every relevant MSFS slider. Raise Master, Aircraft, Engine and Cockpit volume to a clearly audible level. Some third-party aircraft route parts of their engine mix through Aircraft or Cockpit rather than responding solely to Engine volume. Our breakdown of the MSFS 2024 sound controls and output options explains what each control affects.
- Verify the main audio output. On PC, open the Windows volume mixer while MSFS is running and make sure the simulator is neither muted nor assigned to an unused monitor, headset or digital output. Select the intended device before launching MSFS again. On Xbox or PlayStation, check the console’s game-audio destination and any headset game/chat balance.
- Test a two-channel output. When using headphones or two speakers, temporarily select stereo and disable virtual surround or spatial processing. An incorrect surround layout can send part of the engine mix to channels that do not physically exist, even though speech remains audible.
- Reload the aircraft and restart MSFS. Return to the main menu, load a different included aircraft, then reload the affected one. If the output device was changed while the simulator was open, close MSFS completely and launch it again; audio engines do not always rebuild every route during a live session.
- Test without aircraft and sound modifications. On PC, move add-ons out of the
Communityfolder while MSFS is closed. On consoles, disable the affected optional content through the simulator’s content or library controls. Test an unmodified included aircraft before restoring add-ons one at a time. - Repair only the affected content first. Update or reinstall the silent aircraft and any dependency it requires. If several included aircraft remain silent, use the PC platform’s file verification or repair facility, or reinstall the relevant content package on console, before considering a complete simulator reinstall.
If music, menus, ATC and every aircraft sound are missing as well, follow our broader complete MSFS no-sound troubleshooting sequence; that points more strongly to application muting or output routing than to the engine audio system.
Why can I hear ATC but not the engine?
ATC can use a separate communications output while aircraft audio is sent to the main game device, so audible radio calls do not prove that the engine mix is reaching the correct speakers.
Check both output assignments and temporarily route communications and main audio to the same device. Then raise Master, Aircraft and Engine volume together. If stereo fixes the problem, correct the speaker layout before restoring surround processing.
Why does only one aircraft have no engine sound?
A single silent aircraft nearly always points to that aircraft’s package, sound bank, alias or dependency rather than a global MSFS 2024 setting.
Remove aircraft enhancement mods and replacement sound packs first, including ones that claim to affect a whole aircraft family. Reinstall the affected aircraft through its normal content-management method and make sure all required base packages are available. Our aircraft-specific sound package checks cover broken aliases, dependencies and incorrect folder structures.
Do not copy a sound folder from another aircraft as a shortcut. MSFS aircraft can reference packaged sound banks and configuration data; copied files may do nothing or create further conflicts.
What if the engine is audible but extremely quiet?
Very quiet engine audio is a different fault from completely missing sound. If it becomes obvious in external view, check cockpit attenuation, headset simulation, aircraft-specific mixing and output processing using our focused fixes for low MSFS 2024 engine volume.
Should I reinstall MSFS 2024?
A complete reinstall should be the last step, not the first. It is justified only when multiple included aircraft remain silent after resetting sound settings, testing the correct output in stereo, removing add-ons and repairing or verifying the simulator’s files.
Deleting profiles, cloud saves or console reserved data is not a normal engine-audio fix and may remove control assignments or preferences without repairing the sound package.
