I've had a new problem come up where I get quite bad sound stutters. It doesn't appear to affect frame rates and I've got a very high end system so it shouldn't be putting too much pressure on the GPU.

But it's so inconsistent. Yesterday I flew EGLL-KSFO in the PMDG 777 and it was totally fine. Now I'm flying the return leg and I've got bad sound stutters.

Can anyone help? Thanks

I found that reinstalling my chipset drivers and Realtek drivers seemed to fix this issue.  The other thing I did was to disable the Nahimic service which seems to be related.  You may not have that on your system though depending on what type of system you use.

Of course it may simply be that you need to dial back a setting or two.

Whilst I was researching this, someone also sugested that you go to your msfs sound settings and ensure it is set to use the speakers or headphones yoou have installed rather than being set to default.

When you install a graphics card update, be sure not to also install the Nvidia sound drivers or remove them if you have.

The only issue seems to be that I often seem to encounter the same problem after a windows update which means going through the process again.

There is another process called A-volute that might be involved and worth termporarily disabling as a part of your troubleshooting (again this can be system specific).

Good luck with trying to fix it.

I believe I read Martial stated in the last developer update a bug has been identified causing these sound issues and fixed. Hopefully the fix will be included in an upcoming SU4 beta if it doesn't make it into the final SU3 update.

What I don't understand is the inconsistency...yesterday a flawless flight EGLL-KSFO, today a sound stutter fest from KSFO-EGLL.

This is how it is currently. It's awful:

So I reinstalled the Realtek drivers and disabled the Nvidia sound drivers and it appears (one hour in to another flight!) to have done the trick.

Thank you so much

I happens to me time to time.

1) go to control panel / sound settings and select a new playback device. Fly a minute and then go and reset it to where it was before. 

2) go to msfs sound settings and select a new playback device. Fly a minute and then go back and set it to where it was before. 

3) Never choose "default" for msfs sound device. Originally a long time ago, that was not listed in the choices and this issue never happened. The issue started at the same time the "default" setting was added. 

4) Make sure that both mic and speakers are set to the same playback device in windows control panel and in msfs sound settings. This number 4) is the first thing I try.

5) My monitor has a sound device driver. So does Nvidia install another sound device driver. I always disable both of those in windows control panel / sound.

I'm convinced the issue starts when msfs is confused about which device to use each time it makes another sound. (EDIT: momentarily confused, hence the sound hickup).

So I disabled the NVidia audio drivers, made sure MSFS 2024 was using my speakers rather than the default settings.

I flew KSFO - EGLL (on PMDG 777) and all was fine, then flew EGLL - LGAV (all was fine), then on my return (LGAV - EGLL), I got stutters just before beginning descent.

So frustrating that it's not consistent, comes out of the blue. Can anyone add anything to the above great advice?

Yeah I get this too.  I can go one flight no issues next flight sound stutters.  I have tried most things that people have suggested and still get this.  If not for this I would switch over to 2024.  very frustrating as you are not sure whether you will get a good flight or sound popping, stutter one.

Same here, but plagued with this only since I switched from an 13600K to an 9800X3D. Soundcard is still the same, onboard sound chip is disabled in BIOS. In my case, the sound stutters are concurrent with a CPU spike (visible in dev mode), sometimes the spike is big enough to result in a stutter also of the FPS, sometimes the FPS stutter is not recognizable (but visible on the dev graph). 

Also on my end inconsistent. Some flights I suffer from it, the next flight is ok. All I know is that I never had it with the Intel. Never. And it only appeared some days ago, if I would not know it better, I would say with the latest driver release from nVIDIA. But as I was 3 weeks away from my rig, I cant really put the finger on this driver update. And of course yes, I do not have nIVDIA Audio drivers installed, checked that only the sound card is active in device manager and sound settings of W11 and that the sound device is properly selected within MSFS2024.

Annoying...

While people are following all this advice, which may or may not help, Asobo have found the issue and are working on it (at least that is what they implied in the last twitch session - Martial I think), so that is the answer - that is the fix you are waiting for.

I have also started getting it.  It only started for me during these latter stages of SU3 beta, but it may be due to some other change of course.

Waiting also for a potential fix and glad Asobo seems to be aware. But I’m suspicious to have quick fix when I see progress with the VRAM issue. For now, I’ve removed all unnecessary sound tools and drivers.

You can disable drivers from being included in Windows update. One of the first things I do after installing Windows on a gaming rig to avoid problems with your chosen graphics and sound drivers getting overwritten.

From Windows search bar, type ‘Advanced’
Select ‘View advanced system settings’ (this opens the 'System' control panel)
Click 'Hardware' tab
Click ‘Device Installation Settings’
Select ‘No…’ then save the changes

Somewhere I also read that using a too big rolling cache can be the cause of sound stutters? Did anyone ever verify this? I have mine at 128GB instead of the default 16, might that have an impact?

Source ? Never read of this. Could be related to cache file on low access or overload drive?
