No audio in lesson running on your workstation

Explanation

Newer computer software may need to be adjusted to allow compatibility with PLATO plug-ins. 

Resolution

Adjust Sound settings in Windows Control Panel:

  1. Select Start > Control Panel.
  2. Double-click Sound.
  3. Right-click Speakers, then click Properties.

            

  1. Click the Advanced tab.

                          

  1. Change the Default Format to one of the 16-bit settings. 
  2. Click Apply, then click OK.
  3. Run the PLATO lesson again to check the audio.

 

To adjust the sound setting in a Mac:

  1. Open Applications, select Utilities
  2. Select Audio MIDI Setup. Here is where you can change the Hz settings

 

Other Considerations

  • Double-click the speaker icon on the taskbar (at the lower right corner of the screen).
  • Make sure that all volume sliders are turned up and that the balances are centered.
  • Determine if sound is coming from other programs or applications that you use on your computer that have audio associated with them.  Check to see if sounds are generated during the startup or shutdown of your computer. 
  • If sound is heard during any of these tests, check to make sure that the PLATO course you are running is audio-capable.  For more information on PLATO courseware offering audio, click here.
  • If sound is not heard during any of these tests:
    •  determine if speakers or headphones are properly connected to your computer and are powered on
    •   make sure that the volume button is turned up at least halfway.
