I have had the Nvidia HD Audio driver disabled for years and use external powered speakers with the sim, usually running off my motherboard’s built-in audio. The audio stutters and crackling are absolutely not related to Nvidia audio in any way. FWIW, I’ve also tested the sim with my USB-connected audio recording interface and the same stutters and problem are present - this is a sim issue and seems tied to data transfer issues in the core sim generally.

I did not have audio stutters in either 2020 or 2024 until I upgraded from Win10 to Win11 24H2. I upgraded because I changed from Intel to AMD. I got so tired of the stutters that I rolled back to 23H2, this was done about 5 weeks ago and I have not had a single audio stutter since in either Sim. I agree that it is a Sim issue since I did not have it in any other title, but I feel that it is something that is directly tied to some update that is in the current 24H2. I have seen that some on 23H2 also have the issue so it must be something that was added in an update to both.

Its funny Asobo mentioned in their last developer update that this issue is non-reproducible.. like! do we need to connect our machines directly to your Ethernet outlets?

I also don’t experience issues with audio stuttering so I’m unable to reproduce or troubleshoot audio-related interruptions. This isn’t unusual, though - every desktop/laptop is unique and differences in hardware, software or configurations can lead to varying experiences.

So you do use Windows 10? As i mentioned this issue is only happening with 11 24H2 (at least for me).

Yep, I have Windows 10 Pro installed - 22H2 19045.5555
I’ve been saying for a long time that Windows 11 is one of the worse OS when it comes to gaming.

Im gonna give you the reason here since this is my first pc after 20+ years.
But, said that, i have no such a stutters in 2020,f1, avowed, starfield, ds on this very same machine.
I was checking how to rollback to the previous 23h1 version, but there is no such an option in my machine. I did find though some installation with the update number that corresponds to 24h2, but there are 2 more cumulative updates that wont show up in the uninstall list.
Im afraid what happens if i uninstall 24h2 just like that.

As I mentioned, every desktop/laptop is different and there’s no guarantee that reverting to Windows 11 version 22H2 or 23H2 will solve audio stuttering. You can try it, but I can’t guarantee anything. In the Windows 11 thread I created some time ago, I added information on where to download versions 22H2 and 23H2, since Microsoft no longer provides these versions.

After the launch, I haven’t been simming at all. I decided this was the weekend, I got the stuttering and audio crackling usually when on final to land. Although I first noticed it on a very short flight. I am on Windows 11 23H2 and still was getting it, I am sure there is some tweaking I need to do. I built this system last year, for this sim mostly. i9-14900K, 64 GB, RTX 4090. I will try some of these updates, and see how what helps.

For me I’ve noticed that the NVIDIA Audio keeps being installed with every update. Uninstalling it, but also disabling the AMD Audio driver, seems to have fixed it for me. No stuttering what so ever on the last flight.

Guys, I bought a Sound Blaster sound card. I read somewhere that issues might be related to the Realtek audio chipset on certain motherboards. I’ll disable it in the BIOS and see if it helps. I’ll let you know.

I did this (Disabling the Realtek Audio in Bios) without any noticeable improvement, actually it made things worst since if you start the game without any Audio output set, the game simply CTD upon startup, I logged the bug report about this already.
Anyway,
While I think 100% this is a Sim issue that needs to be addressed by Asobo and MS, yesterday I did some BiOS tweaking. Basically I did these changes on the AiTweaking page:
In fact I made just 3 changes, the others were automatically added.
- ExpoI - to EXpoII
- Core tunings Configuration for Gaming
- Precision Boost Override
After this I made a flight that always is problematic at night. LFPG-EHAM,
The flight went butter smooth.
I did one today with many clouds (daylight) EHAM-LFPG and also no stutter, just after landing there were some frame drops but after that I was able to taxi out without issues.
I will keep testing..

Same issue here. Both audio and frame stutter a lot. I switched to SU beta 1 and the problem still exist. I found out that when loading in to the default “online streamed” airport, the stutter occurs while payware airport doesn’t cause this issue.

I rolled back to 23H2 as well (which was a joy with the current state of nvidia drivers…)
Not a single audio stutter since.

Today I put the flight plan in for the first leg of the Austria - Mountains and Music bush trip from 2020. Flew the entire thing without any issues. Well let me rephrase I had some strange graphical anomalies. See the grass in the video, saw something very similar with the trees on the mountains. https://www.youtube.com/watch?v=jTH3j8aLrQI

After three days of testing the Creative Sound BlasterX AE-5 Plus sound card, I have my results. I disabled Realtek in the BIOS and uninstalled the audio driver. And the problems are completely gone. I flew during peak server load times and nothing. I loaded several flights without a single crackle.
So your issues are not caused by the CPU or GPU, but by the onboard sound chip. Realtek. I read that it’s usually because integrated sound cards on motherboards sometimes can’t keep up, especially under high CPU load or if the motherboard doesn’t properly shield interference. That interference then affects the sound as crackling, noise, or dropouts. The Sound Blaster has its own DAC and power supply, so it handles everything outside the motherboard with better shielding and a higher-quality converter. That’s why the problems disappeared.
I highly recommend this to everyone, just make sure your sound card doesn’t use a Realtek chip. Plus, your sound quality will improve significantly

After one week of testing the RTX 5090 gpu, I have my results. No more sound stutters! So, I highly recommend everyone go out and buy one. After all, who wouldn’t spend $2,500 to fix issues in the game they love—even when everything else on their system runs perfectly fine, right?
I hope this highlights the absurdity of some posts in this thread. If everything runs smoothly except for MSFS, then it’s MSFS that needs fixing, not your system or hardware. Proposals to roll back Windows, swap hardware, or buy a dedicated sound card just to get MSFS running without glitches aren’t just absurd—they also delay the real solution. Developers seeing these (pseudo)solutions might be tempted to shift their attention elsewhere instead of addressing the actual root cause.
And by the way, while my 5090 works wonders in terms of FPS, stutters are still there—just not audible yet. And I say yet because, as always, the right conditions (likely streaming-related) will probably trigger the audio stutters again.
Common sense, guys!

So since Asobo marked it as no-repo, here I put evidence, just Asobo devs, remember, me as a software engineer as you are, we know the phrase: “But the client wont use our machines/devices (development machine) to run the app”
Here is short video showing the cracks.. this happens since take off till landing.. each couple of secs apart..
Lets hope/see Asobo revises this.. Hey Im even more than willing to help you testing and debugging this.
EDIT: I can reproduce this on any Aircraft I fly, the Cessna Longitude, the a320new v2, the A321. And people in this thread has posted that also helicopters?
Im just mentioning this in case the devs come back at me saying “Its because you are using the Fenix”
