Hello,

While I’m enjoying good FPS and overall performance in the new sim, the occasional audio stuttering—especially in areas with dense autogen—is significantly detracting from the experience. I’m using AutoFPS with a TLOD of 250 at FL380, yet the stutters persist despite stable FPS and manageable VRAM and CPU usage.

Interestingly, the CPU I was counting on for the transition to MSFS 2024 is typically running at only 22–25% load and around 70 °C, compared to an average of roughly 50% load and 78 °C in MSFS 2020.

Any fresh insights or ideas would be greatly appreciated.

 

1. Ensure that pesky Nvidia audio driver is not installed as it caused sound stutters for me.

2. There's a technique to turn off rolling cache, that might work for you too.

1. Yes, I have it installed, but just disabled it in the Settings completely.
2. What about RC? I have it set to 300GB to prevent any issues related to Streaming. Yes, I opted to have all WU and CU installed, rather then streamed. 

Thanks again

Turning off Nahamic, A-volute and Realtek in the task manager helped for me and ensure that you have the latest chipset drivers installed.  Can't guarantee any of this will work for you.

I've actually set the above to disabled now as I normally use headphones, but need to turn Realtek back on if I need to use speakers.

Also recommended that in the msfs sound settings, your sound is set to whatever you use rather than default.

Nahamic is a well known issue if you ever read the reddit forums.

There is a long thread about it here: https://forums.flightsimulator.com/t/audio-stutters-in-menu-globe-and-on-ground-during-flight/718524/1263

TL;DR: It's related to Windows 11 versions 24H2 and onwards. People have posted multiple "solutions" including sim settings, audio drivers etc. only to come back eventually reporting that the problem is back.

The only way to get rid of the crackling completely is downgrading to Win 11 23H2 or earlier (though that might not be possible anymore) until either Microsoft or Asobo find a solution for this.

I deinstalled that NVIDIA audio driver and still use RC at the default size and have no audio stuttering/cracking at all with a meager systems, see specs in my sig

Note that I did but do not use AutoFPS anymore as I am more than happy with TAA and AMD FSR 2x with fps imited to 35 in the 2024 settings, still giving me an extremely smooth and stutter free experience while - yes - I dialed down TLOD to about 100 and OLOD to 80 which is fine for my airliner flying - so YMMV

Seeing as you have a 9950X3D cpu in your signature, I remember seeing sound-stuttering happening for folks with AMD cpus several months ago?  Maybe it's related to whatever that issue is/was?

No sound stuttering here, Win 11 and a 9950X3D

Hi folks,

If you're experiencing audio stuttering in MSFS 2024, please respond to this post on the official forums to indicate the conditions during which you have this issue:

This is for me the last big  immersion killer that I am suffering from in MS2024.

There was a pretty big thread a few weeks  ago here on Avsim  but if you look back over Reddit/MSFS Forums it does seem to affect quite a few people, would be interesting if one could do a poll who actually suffers from this situation..

For me and I am an AMD 7900X3D, Nvidia 4800, 64 GB Ram its not happening all the time but I would say it happens 75 percent and its definitely tied to CPU Spikes that I notice as soon as they hit red I get the litte pop stutter and its worsened by flying over more dense photogrammetry autogen, if you really want to see it in action go to x4 Sim Rate then it produdces lots of crackles. If I keep the TLOD and OLOD down that somewhat appeases it but not over large cities its always there. Some folks think its a latency issue that is tied to how busy the servers are and there is nothing we can really do our side.

I have tried all the solutions, there are many put forward, from deleteing audio drivers etc  et al but the one thing I cant try is going back to Windows 11 23H2 thats seems to have worked for many people, I am not sure there is a way of doing that anymore if there was I would do it.

I have not contributed to the official forum I will do that now as its good Asobo are looking into this. Thanks SeedyL for getting involved.

 

If anyone is good at making a poll here at Avsim , I am not very technical, would be interested of the numbers of people that have this issue and whether its more tied to AMD/Intel or its a Windows version too...

SeedyL is after anyone experiencing this issue please log it at the MSFS Forums as they may think its been solved on SU4 which for me it has not. I have just posted over there.

Hi folks,

I’ve seen that comments in this thread have slowed down significantly, and so would like to get an update as to whether anybody is still experiencing this issue?

If so, have you found any common factors that still contribute to experiencing audio popping or crackling? I know there’s been lots of recent comments about CPU load being a contributing factor, which has hopefully been resolved now in SU4.

If you are still experiencing this issue, the development team have asked if you can provide some further details such as:

Where in the game flow does the audio crackling occur (menus, flight planning, in flight)?

Which aircraft?

Where in the world? Which airport?

Was AI traffic enabled?

Was it during a MP session? Which aircraft were part of the session?

Alongside this, if there any video examples this would also be very helpful!

Thanks

The issue I was having was that no matter what I had set for RC, once it was full, I would get this rhythmic stutter every second. Basically stuttering while erasing and saving on the fly. If there was some scenery loading during that time, I would also get the audio stutter. So I saw a trick someone had posted to turn it off. Basically, you create a new folder location on your drive. You then start the sim and set it to that location. Once the sim creates the cache, shut the sim down. You then delete that location from the drive. The size will go to 0 and it effectively disables rolling cache. For some reason, both of my sim computers did not like the constant erase and fill once the cache was full. Turning it off has made my sim smooth.

THanks to everyone for the hints. So far, i have updated drivers, changed default sound settings to specific hardware in MSFS2024, and disable NV sound drivers. These were first steps.

And were they successful so far?

Try G550flyer's suggestion and kill Rolling Cache.
