Public bug reported:

In practically any games running under wine or proton I can hear
stuttering and crackling audio. The timing and severity of the problem
varies between games and from one run to another, but it does reproduce
eventually. For example, Horizon Forbidden West and Dying Light 2
reproduce this, especially at times when the game heavily utilizes CPU.
Horizon is especially bad, as after some play time audio becomes
completely garbled because of the constant stuttering, even when CPU is
not fully loaded by the game.

This problem does not reproduce if I replace pipewire with pulseaudio on
the same system - the same games and in the same in-game conditions
running on the same wine/proton versions do not exhibit audio issues.

This reproduces on the built-in audio on the ASUS Maximus Z690 Hero
motherboard (ALC4082 audio codec, logically connected through USB bus).

I have tried adding these settings in /etc/pipewire/pipewire-
pulse.conf.d/10-buffering.conf:

pulse.properties = {
    pulse.min.req          = 960/48000     # 20 ms
    pulse.min.frag         = 960/48000     # 20 ms
    pulse.min.quantum      = 960/48000     # 20 ms
}

This didn't help.
