Solution
The audio returns to its normal level
automatically.
Adjust your Windows volume control
settings:
1. Click Start and go to Settings >
Control Panel > Sounds and
Audio Devices.
2. Click the Volume tab.
3. In the Speaker Settings section,
click Speaker Volume.
4. In the Speaker Volume dialog
box, adjust the volume, and
then click OK.
5. In the Device Volume section,
click Advanced.
6. Adjust the Line In volume, and
then choose Options > Exit.
Determine whether the camera has
built-in echo cancellation. If it does,
disable echo cancellation using the
camera's configuration software.
If the camera is using other special
features (such as face tracking), use
the camera's configuration software
to disable these features.
If you are using Windows XP, you
can use PVX internal echo
cancellation instead. To do this, go
to Setup > Audio and set Echo
Cancellation to Internal.
