SYMPTOMS

   RealAudio Error 50: Cannot open audio device.
When you click OK, you are able to connect to the Web site; however, any audio features of the site are unavailable.

CAUSE

MSN, The Microsoft Network, may be unable to detect your sound card, or you may not have a sound card installed in your computer.

RESOLUTION

If a sound card is installed in your computer, verify that a Windows 95 sound card driver is installed. To do so, use the following steps:

  1. Click Start, point to Settings, and then click Control Panel.

  2. Double-click System.

  3. On the Device Manager tab, double-click Sound, Video And Game Controllers.

If a sound card driver is listed, you need to determine if the driver is configured correctly. Contact the manufacturer of the sound card for further assistance.

If a sound card driver is not listed, use the Add New Hardware tool in Control Panel to install the sound card driver.

For more information about how to use the Add New Hardware tool, please see your Windows printed documentation or online Help.
