No sounds in "Q.U.B.E: Director's Cut"

[Wallari: Last Knight of Cydonia]

Hi all.

Running Debian 11 here. Unfortunately no sounds at all while I’m playing (neither in the splash screen). I have followed past tutorials to fix this issue but no results at all:

1) Already tried to uninstall and reinstall the game;

2) libasound2-plugins:i386 is correctly installed in the system (verified by ‘dpkg -s’);

Any suggestions?
