Hey guys,

lately I’ve been experiencing some annoying sound lag stutters where the sim is loading and the sound will lag / pop. I never used to have this problem in 2020. Now when something would be loading in 2020 it would pause for a few seconds but I guess it’s different in 2024? I have an i9-10850k and a rtx 4070ti super. I also use msfs on an nvme with 2GB internet. I’ve tried multiple things: deleted shader cache, I use msfs auto fps. I have most of my settings on high a few on ultra usually tlod is 200 at cruise and 50 on ground. I do also use fshud ai traffic but turn it off after departure and turn it back on near arrival. I notice the sound lag stutters seem to happen when flying the pmdg 737s, doesn’t ever happen much if at all in fenix or Ifly. Yes I’ve uninstalled the NVIDIA hd audio drivers and my sound device in msfs 2024 is selected towards my corsair headset.

It’s not a end all thing as it doesn’t happen on every flight but I never once had this issue in 2020 and had close to 1500 hours in that sim before moving over to 2024 full time a few months ago.

Any ideas???

Did this, by any chance, start after installing the latest FSHUD version (FSUD Traffic)?

Check your device manager on your PC, and if you have Realtek drivers there, delete them (won't make a difference if your default sound device is your Corsair headset). The issue with the Realtek default drivers installed into most PCs, is that, even when the device is not selected in Windows, it's always active and its DAC (digital to analogue converter) is always running. That causes distortion when another sound device is also running its DAC process.

So yeah, kill Realtek from your PC.

Ok so would this be under the sound part of the device manager? If so it’s not there

Your PC may not use Realtek (many motherboard maunfacturers are moving away from these chips).

The point is multiple ADC/DACs (converters) running.

Here's my pic. I got a new motherboard 2 months ago and, until this thread, had forgotten to disable my onboard audio drivers too (Mine aren't Realtek either). You can also see the Nvidia Audio driver is there too, and enabled. This is because I updated my Nvidia drivers last week and hadn't yet disabled the audio driver.

All told.... I'm glad I read this thread as I needed to do my own housekeeping too!

There is no risk to this - if there are any problems, you only need to go back to the Device Manager and (re)enable those drivers.

Ok so basically i need to disable any non device other than my Corsair headset?
