State of Decay (241540) sound crackling with Pulseaudio

Steam client version: Aug 29 2018, 15:10:00
Distribution: Arch Linux 4.18.5
Opted into Steam client beta?: Yes
Have you checked for system updates?: Yes
Proton Version: 3.7-4 Beta

Please describe your issue in as much detail as possible:

Game starts and works with some stuttering, presumably because of the textures that are loading in. Goes away after a while. The sound crackling is AFAIK a common problem with wine.

Steps for reproducing this issue:

1. Start the game
2. Load into a save
3. Every sound crackles, including menu music

Steps to fix this issue:

I don't know how you would fix it for every system, but I fixed it for other games, for example StarCraft via these commands:

alias wine='PULSE_LATENCY_MSEC=60 wine' or export PULSE_LATENCY_MSEC=60

Reproduce State of Decay on Arch Linux with Proton 3.7-4 Beta, following the listed save-loading steps and checking menu music as well as game sounds. Compare the behavior with the reported PULSE_LATENCY_MSEC=60 setting; done means the crackling is resolved without regressing startup or gameplay audio.
