Music but sound effects on kynseed via lutris

I have bought Kynseed on GOG. I downloaded the installer of the game and installed it via Lutris in a wine environment. I noticed however that I hear music during the game but no sound effects. I read some about Pulseaudio and ALSA but switching this in the lutris settings does not help.

I normally use bluetooth headphones. Connecting it by cable or using my laptop speaker does not resolve the issue either.

Does somebody has some tips on how to resolve the issue?

Lutris version: 0.5.12
Linux version: Linux mint 21.1
