Hi, That’s exactly what happens to me now and then, ramdomly.
No apparent reason, thou…
I hope this will be solved soon.
Greetings

I’ve just come from the rolling cache causes stutters thread:
can people experiencing audio stutters try to:
- Delete the rolling cache (you can find the location of the file in the Online section I believe)
- Set rolling cache to 120GB (note: you can not set a lower value after you’ve set a high value. However, deleting the file and rebooting the sim, resets the rolling cache to the minimum 16GB, so no worries).
- Set pre-caching to Ultra
And come back and say if you still experience the stutters ?
I’ve had initial good flights and then stutters all over the place. Doing the above, helped with the audio stutters. Still have graphical stutters, but one booboo at a time.
Also interesting that this is still marked as Feedback-Logged. Clearly people are having issues. A bug must be entered and Asobo should try harder to repro this.

Just wanted to say I, and many others who simply can’t be bothered to post here (don’t blame them) are having this issue - I suspect it to be an Asobo server issue/optimisation issue that presumably will be fixed in a future sim update which brings optimisation

Do you have the same issue if you follow the OP’s steps to reproduce it?
•
Provide extra information to complete the original description of the issue:

If relevant, provide additional screenshots/video:
• I get the audio and video stuttering during flight. It seems to start up when there is a lot of radio transmissions.

I’m also after stutters and Audi crackles but only after su1 so it has to be asbo side. I’ll delete rolling cache again and see if that helps

Try turning Fauna off.

For me it helps to undervolt my GPU

Try uninstalling nvidia hd audio driver. This fixed it for me.

Can confirm this is directly tied to the streaming/internet behavior within the simulator, at least in my uneducated opinion, hence why Asobo can’t duplicate it. It used to be occasional at best pre-SU1, but now it’s constant and easily reproducible post SU 1 release. It seems like when the program calls for additional ortho scenery and objects, the server can’t deliver the information fast enough, so it shows up in batches, the sim then calls for more and then hammers your CPU to process more then it can handle at once. You used to be able to account for this with increased rolling cache, but this occurs at all values of rolling cache up to 150 GB for me. I have 64GB of Ram, 7900X3D, and a RTX 4090. I do not have the Nvidia HD driver installed.
Can be easily reproducible. Just go to free flight, then zoom into a populated area fairly quickly. All sorts of stutters until it finishes loading the ortho.

For me this is happening in cruise mostly where instead of freezing my PC, the entire audio for my PC cuts out entirely. music from spotify, youtube videos go silent. everything. im losing my mind trying to figure out why or whats causing it or how to fix it.

So I popped open Dev mode and watched my FPS values as I flew from Stuttgart to Amsterdam and I noticed something. The audio glitches and cut outs happen when download speed stalls out trying to load in the scenery.
Whether it be as you are flying, in the world map or at the airport. When the download speed hitches, this seems to cause a spike in CPU latency, which in turn causes my PC to soft freeze or bog down so much that (for me at least) all of the audio on my PC goes silent for a length of time. I say “for a length of time” because it isn’t always the same. it could be milliseconds, or from what I’ve experienced, it could be anywhere up to 5-6 seconds. It depends on how long it takes the CPU to chew through the wave of data it receives when the data stream untangles itself.
For reference I have a Ryzen 9 5900X, an Nvidia RTX 4080 and Gigabit internet with a consistent observed 900Mb+ download and around 42Mb upload speed.
I hope my findings help someone to find a solution. I’ve decided to try and limit the bandwidth usage from within MSFS24 to see if a hard limit on the data stream will smooth out the overall spikes and dips.

(On XSX)
The crackling/studdering audio issue has been noticeable for a long time but it’s gotten so bad that I can’t even get one flight in anymore without it becoming far too annoying to continue the flight. I used to at least be able to do simple, slow flights with only minor crackling, which was still bad enough, but now it’s awful.
This needs some kind of an emergency fix IMO. I do doubt they’ll do an emergency fix but I also can’t believe this will go until the next SU if not longer. For me this does effectively make the sim unplayable.
I may try to upload a video if I get the motivation to load into the sim but honestly the other videos posted here are exactly what is happening. I get it both in faster jets like the A-10 and in the Skywagon, Draco, Joby, and likely everything else.

So I had this and as others have mentioned, it kept getting worse (from a start of random stutters in heavy scenery and no audio stutters).
Deleting the rolling cache and setting the size again to 120GB (since it resets), has had an immediate positive effect reducing not only the amount of stutters but also almost completely eliminating audio stutters.
I have further:
- Disabled SVM (i’m on an AMD 9800X3D) from my bios
- Disabled IOMMU
- Disabled Nvidia Audio HD Driver (tried uninstalling but Windows keeps putting it back, so just disabled it from Device Manager) - this on its own did not fix the stutters caused by the rolling cache. This was the first thing I did and everything else listed here was still needed.
SVM and IOMMU are virtualization options in bios (to run virtual machines, etc. ) so if you’re not doing that, ok to disable. Found some older threads that recommended these to improve stuttering.
- And I have reduced texture resolution to Medium, since I only have 12GB VRAM.
With all of these, I am now getting almost no stutters and definitely no audio stutters (so far). Tested with A350 inibuilds (very heavy on performance) and a320 FBW (light but still airliner) flying between 2 3rd party airports (EDDH and ESSA).
Definitely Asobo needs to get working on fixing the rolling cache filling up issue + optimizations. It’s not logical that the sim would wait for any scenery to load in, it clearly has super low resolution scenery to put in place when the internet connection is lost, so it should just use that until it can load in appropriate scenery at a rate at which it doesn’t impact the rest of the sim’s performance.
But doing the above has helped me so far. Still waiting and testing.

Has this still not been fixed? 
I’m flying the 2020 again. Uninstalled the 24. I’ll see how it looks in a year. Doesn’t make any sense at all right now.

WOOOOW… I can confirm , removing the NVIDIA HD Audio Driver fixes the Stutter also for me!!!
Crazy, because, there is no audio device connected with. Removed, Reboot, Stutters gone…

I had the same effect at the weekend, I only use a USB speaker via Optical In.
I simply uninstalled the Nvidia HD audio driver and now only use the Realtek USB driver
My monitor has no speakers at all, now the MSFS2024 runs really smoothly after the SU1.

Im gonna try the BioS thing, I don’t use virtualisation, so … whata heck, I loose nothing trying this.
