Hi, tumanovalex.
I'm not really sure what you're asking. Do you have a question about specific inputs or outputs of the sound VIs? Also, what version of LabVIEW are you using? If you can explain your question a little differently, I'll see if I can help. In the meantime, take a look at this
example program that reads data from a sound file. Good luck!
