Sound no longer working during flights 12/23/2020

Same issue. Menu sounds and music is fine, but no ATC or plane sounds. My Community folder was empty, but I do use PACX which installs in the same directory as MSFS. Not sure if that could be causing the issue.

Very frustrating.

I have even reinstalled MSFS, still very frustrating with the sound problem. Are we the only ones who have the sound problem? This is really annoying now. I have no idea why. After the reinstallation, I didn’t install any addons, so the pure MSFS installation.

Managed to get sound back today with all mods enabled. Restarted Sim a few times still had sound
Restarted Sim just now as I’d been playing for a while. Back to no sound.

I found the solution. Didn’t have a headset connected. I connected my headset, defined it as the input source in Windows, started the MSFS and the sound (motor and radio) everything was back.

Is your headset set as the default audio output for Windows? Not sure how changing an input would affect the output, and only some of it when the music and interface noises still work.

I’ve just run some more tests based on what you’ve just said. (Using the PA44 Seminole and EGMC as my departure airport each time to keep it the same).

Default sound settings = MSFS set to Sound Blaster Z (default)

  • Load MSFS, change sound card to onboard (not default) and carry on playing = Sound stays working
  • Restart MSFS = Sound NOT working
  • While MSFS is still running, change sound card to Sound Blaster Z (default) and carry on playing = Sound stays NOT working
  • Restart MSFS = Sound working

Bug report to be filed then…

In MSFS under SOUNDS, see if Spatial Sound is ON. If so, turn it OFF and see if that returns your sound.


I set a sound input source in the Windows sound settings (i.e. headset voice input), then started MSFS and all sounds were available again. MSFS sound settings:
I have communication choices based on headphone simulation; Room sound image off

i cleared my community folder (even deleted it) and still no engine sound. I get ATC voices but no engine sound.

Some (many) of the mods change the official Asobo configuration files for the default aircraft and add sound files outside of the community folder when you run their installer.

If you want to verify that the problem is with the default aircraft, rename the official aircraft folder and download that aircraft again from the marketplace. Shut down the computer and restart, then start the sim again, select the default plane, and see if the problem still exists. If the problem goes away, then the mod was responsible, likely from changing the official files.


Yesterday ATC sound go strange. I still hear my own voice, but the ATC either responds very softly or has no voice at all. I do not know what it depends on. I checked my voice settings, tried to change them, but no changes were made. The problem is with both Azure and Microsoft sounds.

I did this and reinstalled 172 classic and still no sound :frowning:

I did not have this issue before v1.12.13.0. I have always run the sound from MSFS on another output source other than the default. On the odd occasion I streamed, it meant only the audio from MSFS went to OBS and not system sounds etc.

I can reproduce the issue using the steps I posted above, 100% of the time (with and without addons in the Community folder).

This is how I got the sounds to stay working:

  • Run MSFS
  • Go to Options > General > Sound
  • Press F12 or click on ‘Reset to Defaults’ (Mine reset to the below)

  • Press F11 or click on ‘Apply To Save’
  • Press the Windows key on keyboard and type in Sound Settings, click on the result
  • Scroll down and click on ‘Advanced sound options’
  • Check that ‘Microsoft Flight Simulator’ is set to ‘Default’

    (I clicked in the top drop-down box next to ‘Microsoft Flight Simulator’ and changed it to something else then back to ‘Default’)
  • Close ‘Sound Settings’
  • Quit MSFS (I tried with and without rebooting, made no difference)
  • Run MSFS

The only changes I made after running MSFS again was some of the levels. i.e. Aircraft Engines and Warnings sounds down to 50%.


does the above fix work with addons in community?

I’ve had the same issue. In game music, but no in-cockpit sound.

Logged a call and told to update to latest Windows patch. Which I did and no change.

Emailed them back but since then radio silence, just like in the cockpit.

Clearly this is a wider issue than just my PC so why aren’t we hearing about a solution, this game cost a lot of money and the support seems to be lacklustre

if you get a response from them I would love to know if it works, this is starting to really bother me!

Can confirm that this works.

I was also using a different audio output (for streaming purposes). While not ideal, I do have both UI sounds and menu music back, and in-game audio when using Spacial Sound.

The issue probably has to do with VR using a different audio output?

Hopefully they’re aware and do we get a fix with the next world update.

Yes, you are correct. I stumbled across this exact same “fix” and I no longer have a sound problem. Apparently the update changed a setting in Windows 10, as described above. Go to Settings, System, Sound, Advanced Sound options (app volume device preferences), Microsoft Flight Simulator and you may have to change speakers to realtek (even if that’s not what you are using), and device to default. This fixed my sound problem instantly.

works great! Just need to do it everytime I launch the game

Yes I have a feeling it’s very much to do with the VR side of things.
I filed a bug report and it has been taken internally now, so fingers crossed!

Oculus Rift. The sound ONLY goes off when I click on VR mode?
