Hello �
From my little knowledge in the German language, I think you are asking how you can acquire data from your sound card.
If this is right, please take a look at this
Discussion Forum thread. You might find it useful.
Also, like LunaBlue was saying (I think), you can take a look at some of the examples that ship with LabVIEW. For this, go to Help >> Find Examples. Once the NI Example Finder opens, select the Browse tab and in the middle window (the one with the yellow folders) go to Hardware Input and Output >> Sound. These examples might help to get you started.
Hope this helps.
