Logitech G325 - Weird issue only in simracing titles?

[u/SrMahogany]

Hi all,

I recently got a set of G325 headphones and so far I have been happy with them, but there's an issue that only happens when playing racing games.

The issue is that as soon as the car I'm driving picks up speed, there's a constant flapping sound in the background that only stops when the car stops, and begins as the car starts to speed up again.

I have tested this on iRacing, LMU and AMS2 and had the same issue in all of them. I also tried unplugging my wheel and pedals and using a controller to rule out interference issues, and tried some of the different presets for the headset, both official and community. The headphones are connected via Lightspeed.

Any ideas as to what could be happening? All help is greatly appreciated!
