Helldivers 2 sound crackling/popping

[Azertinv]

Describe the bug
Sound crackling and popping when playing Helldivers 2

To Reproduce
Steps used to reproduce the behavior:

1. Set Helldivers 2 launch options in Steam to gamemoderun %command%
2. Launch the game
3. Hear crackling when on the bridge of the ship

Expected behavior
No sound popping, fixed when not using gamemoderun.

System Info (please complete the following information):

• OS and version: Endeavouros (Arch linux based)
• GameMode Version 1.8.2

Additional context
It seems that gamemode pins all the threads of helldivers to only 4 threads, other people have had issues with sound crackling when their cpu usage got too high so it may be related.
Also note that I'm running an i9-13900K and I have P/E cores.
If there is a way to disable core pinning with gamemode I could try that.

Ok so I've added this to my ~/.config/gamemode.ini

[cpu]
park_cores=no
pin_cores=no

and it fixed the issue

I tried both options separately and here is the cpu usage.
pin_cores=yes

park_cores=yes

So probably a P cores list detection issue ?

You guys mention cpu freq heuristics here #352 (comment) but it doesn't seem to work on my machine ?

I fixed the cpu pinning by doing it manually for anyone having the same issue, add this to your ~/.config/gamemode.ini

[cpu]
park_cores=no
pin_cores=0-15
