1) Open the Microsoft Windows Media Player (in the Accessories program group).

2) Select Device - you should see "Sound" and "MIDI Sequencer" beneath it.  
   (If not, then the drivers are not installed properly.  Re-install these.)

3) Choose "Sound" and select one of the WAV files listed. 

4) Click on the [Play] button and see what happens:

   * If the bar never moves, there is most likely an IRQ conflict. 
 
   * If the bar moves but stops, there is a DMA conflict. 

   * If the bar moves all the way across, the problem may be with the 
     audio connection: 

     a) Check to make sure the speakers are plugged into the correct jack. 
        The top is SPKR OUT and the next to top is LINE OUT. 

     b) If the speakers are plugged in correctly, then plug a pair of 
        headphones in and try playing again.  If you hear sound, then either 
        the speakers or speaker cable are bad.  

     c) If no sound comes from the headphones either, check the mixer 
        settings, making sure the sliders are all up and nothing is muted.
