No sound on websites while CBE9 is open

Not only my metronome is acting up all weird, but since some days I don’t hear the sound of flash video’s while Cubase Elements is running.
I have been able to use them simultaniously, but for some reason it won’t work no more.
I used to work on songs and check for samples to use in the current project, but now clicking the play button on looperman doesn’t do anything. It just won’t play any sound.
I can watch youtube video’s, but also, no sound.

I think the metronome problem and this one are caused by the same thing but I could be wrong.

Help is much, much appreciated.

Oh wow, I found it!
