This may indicate a problem with the sound card installation. You should start by downloading and installing the latest drivers for your sound card. This will normally resolve the problem, with the exception of some Windows 2000 systems.

If you have Windows 2000 and reinstalling the sound card drivers didn't resolve the problem:

Some Windows 2000 computers have a driver called "Unimodem Half-duplex Audio Driver" that can cause a conflict with multimedia applications. This is an older driver that was included to support a specific type of telephony device. Chances are you don't need to have this device enabled. Follow the instructions below to disable the driver and see if this resolves the problem. You will need to restart your computer after you do this for the change to take effect with the multimedia application.

  1. Go to Start | Settings | Control Panel | System.
  2. Select the Hardware tab and click the Device Manager button. Expand the 'Sound Video and Game Controllers' section.
  3. Look for "Unimodem Half-Duplex Audio Driver". If you see it, right-click on it and select Properties.
  4. In the Device usage menu, select 'disable...'
  5. Press OK, close out of the Device Manager and System Properties windows, and restart your computer.
