When I launch the game red alert 2 without installing the sound card, everything goes well. May if I run it with sound install in Reactos, the game will crash just before the main menu is fully displayed. It lacks all the buttons of the menu and the beginning of the music turns in a loop. In addition, I can no longer regain control of Reactos. If red alert 2 is blocking, other applications can also do this. That's why I point this out.
