Troubleshooting
Sound and microphone problems
Symptom Possible solution
I hear noise when con-
necting a headphone
to the computer.
Check if the earphone works well.
- 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 is resulted from high instantaneous current. This
is a normal phenomenon.
I do not hear sound
from the built-in speak-
ers.
Check if the speaker volume is set too low or is muted.
- Click the volume icon, , in the system tray to check the
Windows volume 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 connected 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 files 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 file again. If the audio file still cannot be
played, it might require a codec that is not supported by Win-
dows Media Player.
For more information about available codecs, see the docu-
mentation for Windows Media Player at the Microsoft web
site.
