Yeah in my case occur same thing, i tested this title around june of this year

and can confirm too proton reports show if use wined3d audio back to work
I completely forgot there already was a issue for this one https://github.com/doitsujin/dxvk/issues/3493
So closing this one as a duplicate
When using dxvk with Project: Snowblind sound will play fine for the intro videos but once you get to the main menu sound will disappear and continue to be gone once you are fully ingame. This does not happen with wined3d.

Attached traces of both dxvk and wined3d.
There are two of each because once you start the actual game from the main menu a new one will get created and you can see the window quickly shut down and open another one i think. Though note the sound is also gone in the main menu itself before this happens.
Edit: Yes the main menu is a seperate launcher executable.
