Detailed Information:
If you are unable to hear audio playback when
using the LearnKey software, then checking speaker
power/volume, adjusting the sound card configuration,
adjusting the system’s volume sliders, closing
background programs, or verifying your hardware setup
will usually fix this problem.

Solution:
Solution 1:
Check your Speaker power &
volume.
The first thing to check is if your
speakers are connected properly, have the power turned
on and the volume set appropriately.
Solution 2: Adjust the system’s volume sliders.
Windows has independent volume controls for each
different type of sound. To make sure the volume
controls are not set too low or muted on your
computer:
- Double-click the speaker icon in
the status area of the taskbar in the lower right
corner of the screen.
- Make sure that Mute is
not selected for the Volume Control (Play Control),
Wave (Wave/Direct Sound) or CD Audio sliders; they
should be set to reasonable levels.
If the
Volume Control (Play Control), Wave (Wave/Direct
Sound) or CD Audio sliders are not displayed, add
these sliders to the list to be displayed:
- Select the Options menu and choose Properties.
- In the Show the following controls section, select the
Volume Control (Play Control) or Wave (Wave/Direct
Sound) check box.
- Click OK to close the
Properties window.
Solution 3: Make sure
that ’Use Only Preferred Device’ is selected in the
Control Panel.
- Click on Start -> Settings
-> Control Panel
- Double-click on the Sounds
and Multimedia icon (under Windows XP it is called
"Sounds and Audio Devices")
- Click on the Audio tab
- Take a note of what your preferred device
is. If it states ’No preferred device’ then please see
step 11.
- Put a check in the "Use Only Preferred" device box
- Click on the ’Sounds’ tab
- Click on "Asterisk", so it is highlighted
- Click on the "Play" button to play the sound.
- Do you hear the sound effect? If not skip to
step 11
- If you do, click on "OK" and skip to step 12.
- There is a problem with the way your
sound card is installed in Windows. Please see your
hardware provider to properly configure your sound
card.
- You either have a faulty install of your
Video Compression or you do not have it installed. For

Solution 4: Close all other applications running
on your computer.
Solution 5: Check the sound card for any
conflicts with another device.
To check the status of your sound card:
- Click the "Start" button, point to
"Settings", and then click "Control Panel".
- Double-click the "System" icon. (Windows XP: Click
Switch to Classic View and then double-click the
System icon.)
- Click the "Device Manager" tab
(Windows 2000/XP: click the Hardware tab, then click
the Device Manager button.)
- Double-click
"Sound, Video and Game Controllers", then double-click
the sound card icon to open "Properties".
- On the "General" tab, make sure that the "Device Status"
message is "This device is working properly". If the
device is not working properly, contact the sound card
or computer manufacturer for further assistance.
- Under "Device Usage" option, make sure the
"Disable in this hardware profile" option is not
selected. In Windows 2000/XP the Device Usage field
should indicate "Use this device (enable)".
Solution 6: Update your sound card drivers.
Your computer uses driver software to send
information to the sound card. LearnKey software may
not be able to play sound if the driver software is
out of date or corrupt.
We recommend you
update your sound card drivers on a regular basis. To do so
visit your sound card manufacturers web site.
