Surveillance Station Surveillance station sound available on all PCs eexcept one. Why?

[Jenner]

Guten Tag,
My SS is connected to 6 cameras, mostly HD with microphone. The sound is properly recorded and available life and for download on all my PCs but one. Unfortunately this odd PC (running WIN7 Ultimate as all others) is the one always online with my DS713+ and the Surveillance Station. I would thus like to listen to the sound also on this PC, specially life. I have not found an answer to my problem on the forum. Does anybody have a suggestion?
Vielen Dank,
Jean

mmh... do you have some more details about this one PC? What's special? Soundcard? Problems with sound in other programs or web applikations?
