With this latest build, sound crackling, and sound pauses are worst then ever.
There is a simular topic Audio Stutters In Menu / Globe And On Ground / During Flight vith high vote count.
But with this latest beta buld it escalated and is worst then ever and i think it should be logged as issue in this beta also..
Here is a video:
FS2024- SU2-B18 - Made with Clipchamp_1746270575216.mp4
I tried to delete rollig cache. Same.
I had BATC enabled this flight and you can clearly hear that sound from BATC is working ok. so other apps dont have issue with sound, only FS. Its the same without BATC so it is not some concurency issue.
Its interesting that rendering does not stutter in this one. only sound.

I had this problem but found out it was a Fenix2gsx app…… do you have this add-on?
Same here. I had this exact same issue. However I disabled fsrealistic on my last flight and had no audio popping. I will do more flights without fsrealistic to confirm whether or not that was the issue for me.
I found that any tinkering with cache, sound devices, addons etc is just random fix for the moment.
If I restart pc, next flight is ok, then the next one is not, then I just delete cache, then its ok, but again next one is not ect ect…
I do not have any addons.. just fenix and BATC. But same issue can happen whitout BATC. It is totaly random.
There is some major platform issue with this. It is present for long long time, but with this build it is the worst for me.
Yes now it cracking sound and stuttery always on each flight. Is horrible 
for me the stuttering stops when I am out of focus on the main screen. The minute I click back onto the window running msfs the audio popping/stutter returns. I thought fsrealistic had something to do with it but I was wrong. I even tried updating my audio drivers to no avail
Very interesting find…
At the end it probably is an issue with rolling cache.
Yesterday I deleted rolling cache and one short flight was ok, next long one was terrable with sound and render stutering. (After deleting RC it defaults to 16GB)
Today I started flight with Fnx A320 and it started terrable. Lots of cracling and stutters.
Then I entered settings in the middle of the flight and set RC from default 16 to 100. It rebuilded it, and after that the rest of the flihgt was just perfect. Smooth, no sound o render stutter. Just perfect.
So it seams that when RC is full and starts rewtiring it self issue occures.
Update: Nope.. till the end of this 400nm flight sound crackling still occures. Much less, but its there. And i thing it is not possible that 100GB RC got full…
Yeah I was about to ask. These sound stutters occur mostly going out and into airports. Once you are above 10,000 feet when the sim becomes mostly smooth, the sound stutters are gone.
Furthermore, this is not a hardware or and 3rd party software issue. This is an MS/Asobo issue plain and simple. Folks need to stop trying to look for a cause or fix. There is no fix. You might think you did something to fix it but in reality it is just a roll of a dice and eventually the issue always comes back.
The fact that Asobo has not even acknowledged this issue is just beyond me.

Well.. only it is present in cruise also…
Its just a roll of a dice as you said..
Mine is set to 200gb and I still get these frequent audio crackling stutters
I notice it in cruise as well. But you are absolutely right, the issue does always come back. It’s definitely frustrating
I just disabled FSUIPC7. I am three flights in and have not had a single sound popping/stutter in flight. Do you have FSUIPC7 installed on your system?
Nope… I have just fenix 320/ini350 and batc active. or just fenix/ini350 without batc…
Im sure its just another roll of a dice 
You’l be reporting her that they are back soon enaugh
I’ve been chasing this issue since .12 SU2 Beta, got frustrated thinking it was my CPU.
Upgraded from 7900X3D to 9950X3D… still had the stuttering and audio cuts. Worked for the past two weeks on this issue. Was really shocked that I was encountering it even with the new chip. Very frustrating.
As of tonight, (after two weeks of testing, tinkering, and stable solid flights) I can say, my issues are 90% resolved (aside from the occasional stutter as a result of the bug that’s been logged on final approach).
For me it was two items:
-
My undervolt causing significant instability. (CPU usage would spike, hitting CPU freq/power limit and then causing the stuttering/audio cut out). Finally was able to figure out the undervolt and OC items with my chip that even hitting the limit would remain stable and shifted the curve to being GPU limited…finally. (This doesn’t resolve the simulator causing these spikes, but I was able to tinker with the OC to make it stable in the event that the sim “Spiked” CPU usage.
-
Stopped using any driver level or Frame_Limiter in UserCFG file to lock frames to a certain FPS and using FG to artificially boost up to monitor refresh rate.
For me, limiting to 30 FPS outside the sim and attempting to boost to 60 FPS with FG, locked me at 30 even with FG ON. So there really was no point in using FG. All it did was force my CPU to work harder. Significant stuttering, CPU busy times, and audio cutouts were noted trying to use this.
Attempted to try with 60… Same result.
Attempted to use 120… Same result.
Set everything back to default in terms of driver level settings and used the in game monitor refresh rate setting to 50%, made sure low latency mode was “Off” and then turned on FG. Instant reduction in CPU workload, busy times, stuttering, and audio cracking. With it set to 50%, this would give me a base rate of 60 and with FG enabled, I was 105-120fps. Framerates with Fenix were 80-90 with no stuttering.

I am not sure if this will work for anyone, but wanted to share what I encountered, tinkered, and found worked for my hardware.
I had a single instance of crackling audio on an earlier beta release, but since then nothing.
