Guild Wars 2 : brief audio glitch on certain actions

The game runs great on bazzite. The only issue I have left is that the audio glitches very briefly when I open TP (Trading post) or Wizard vault (and also when changing map or login out).
Note : from my understanding TP/wizard vault in Gw2 is calling an embedded chrome browser.
These actions seem to be linked to CPU usage bursts.

I tried with many proton/protonGE versions, and tweaked some pipewire/pulse settings with no luck.
It's the only game I have this kind of issue.

With advice from @HikariKnight I tried the following with no luck :

I put this in

~/.config/pipewire/pipewire.conf.d/wine.conf

~/.config/pipewire/pipewire.conf.d/wine.conf

pulse.rules = [
    {
        matches = [
            { application.process.binary = "wine64-preloader" }
            { application.process.binary = "wine-preloader" }
        ]
        actions = {
            update-props = {
                pulse.min.req          = 128/48000
                pulse.min.quantum      = 128/48000
            }
        }
    }
]

pulse.rules = [
    {
        matches = [
            { application.process.binary = "wine64-preloader" }
            { application.process.binary = "wine-preloader" }
        ]
        actions = {
            update-props = {
                pulse.min.req          = 128/48000
                pulse.min.quantum      = 128/48000
            }
        }
    }
]

Any other ideas ?

Update : I forgot to mention there is also a small graphical hiccup/frame drop at the same time of the audio hiccup.

I tried to change CPU scheduler (I tried all available) by changing it in and then (or restart)
-> No improvement

framedrop would make sense when it happens as thats usually when audio is playing catchup when its cpu bound

For the record, for today at least, no sign of this bug anymore. I launch gw2 with GEproton 10.13 for some time now, but I think something fixed the issue in 42.20250828 or earlier update

I saw someone talking about a bazzite specific scheduler patch that was not needed anymore and remove, maybe that was it

maybe you can try to force pipewire to use 48000hz only

if this issue re-manifests itself, anyway

皇皇家海星 maybe you can try to force pipewire to use 48000hz only

I tried that but it had no effect.
This issue seem fixed, still not occured, it was permanent before
