most users report no sound output once in a while or right after starting the game, in my opinion this is a problem related to vsync/monitor refresh rate at least for my setup.
in my config i made two "audio related" changes, which eliminates the sound dropout problem. I don't know if and how this can be explained technically. I only know that it works for me (5.1 setup), no matter which render you use (vulkan/d3d12).
use_dedicated_xma_thread = false
vsync = false
