Symptom Possible Solution
I hear noise when con-
necting a headphone to
the computer.
• Check if the earphone works correctly.
• Connect the earphone to other devices, such as a radio, to see if you can
still hear that noise. If the noise persists, the earphone may be out of order.
• If you hear the noise only while inserting the earphone to the computer, it
results from high instantaneous current. This is a normal phenomenon.
I do not hear sound from
the built-in speakers.
• Check if the speaker volume is set too low or is muted.
• Click the volume icon,
, in the system tray to check the Windows vol-
ume controls.
• If you are using a program which has its own volume control, ensure the
volume level is properly set.
• Unplug your headphone and external microphone if they have been con-
nected to your computer.
The external micro-
phone does not work.
• Check if the external microphone is properly connected into the microphone
jack on your computer.
Certain audio les can-
not be played, and the
Codec error messages
appear.
• Check if Windows Media Player is set to automatically download codecs.
• Right-click on the menu bar, select Tools from the opened menu, and then
click Options.
On the Player tab, in the Automatic updates area, select Once a day,
and then click Apply and OK to complete the settings.
Then try playing the le again. If the audio le still cannot be played, it
might require a codec that is not supported by Windows Media Player. For
more information about available codecs, see the documentation for Win-
dows Media Player at the Microsoft web site.
