Sound and microphone problems Troubleshooting Symptom I hear noise when connecting a headphone to the computer. I do not hear sound from the built-in speakers. The external microphone does not work. Certain audio files cannot be played, and the Codec error messages appear. Possible solution • 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. • 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. • Check if the external microphone is properly connected into the microphone jack on your computer. • 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 Windows Media Player. For more information about available codecs, see the documentation for Windows Media Player at the Microsoft web site. SN22A1 52
