Additional dsound:dsound crash on VBox tester

Actually I wanted to wait until the testman is reliable again before merging https://github.com/reactos/reactos/pull/6761

because I feared that the additional dsound:dsound crash on VBox is related. I am not entirely sure about it yet, but for me it seems as if merging https://github.com/reactos/reactos/pull/6761 introduced it.

Maybe it is a bit too early to say for sure.
I mentioned this worry already here before the merging https://github.com/reactos/reactos/pull/6761#issuecomment-2063936470

I guess the post got lost a bit between the other review-comments.
