Usually, this is because the camera was not installed properly, or wrong or
outdated drivers were used.
The first thing to do is to check Creative's web site for updates, and
install instructions.
Some camera required that you install video and sound drivers separately, or
even install twice.
C Lab is not known for "quality" drivers and related software, and they
often do not release updated drivers for older products. I have an external
sound/midi device from them that they refuse to provide updated drivers for,
and there is no equivalent device in the current product lineup.
