Symptoms

You are running a presentation on a portable computer and a projector, but the projector is not playing any of the sounds in your presentation.

Resolution

Try any of the following:

• Check volume adjustments   The volume must be turned up, and muting functions must be turned off, both on the computer and on the projector:
  • Adjust the audio source on the computer by using the sound and audio device settings in Control Panel (click Start, and then click Control Panel). Some computers also have hardware volume controls, which may be integrated into the keyboard or located elsewhere on the machine itself.
  • Adjust the audio settings on the projector. Projectors may have sound buttons on either the remote control or the projector itself, or both. Refer to your projector documentation for information about volume control.
• Check audio input connections   Make sure that your audio input connectors are set up and working correctly:
  • Make sure that the audio input connectors are completely plugged in and are connected to the appropriate outlets.
  • Make sure that you are using the sound cables that were provided by the projector manufacturer.
• Check sound file availability   Make sure that your sound files are available to your presentation. If the sound files are not embedded (embedded object: Information (object) contained in a source file and inserted into a destination file. Once embedded, the object becomes part of the destination file. Changes you make to the embedded object are reflected in the destination file.) in the presentation itself, but only linked (linked object: An object that is created in a source file and inserted into a destination file, while maintaining a connection between the two files. The linked object in the destination file can be updated when the source file is updated.) to it, then make sure that the linked files (or copies of them) are located in the same folder that your presentation is in. Otherwise, the presentation may not be able to access them.

   Note   If the path name of a linked file exceeds 128 characters, Microsoft Office PowerPoint is not able to find and play that linked file. In such a case, you can either rename the linked file, or shorten the path name by copying the linked file into the folder where your presentation is located. Then either update links automatically by using the Package for CD feature, or update them manually by removing the sounds from the presentation and then adding them again.
