Sound Problems




No sound at all from your speakers?
Be sure to check these obvious things first:-
(i) If the speakers are mains powered, check that power is getting to the speakers. Usually, one of the speakers has a red light showing and you might hear a faint hum.
(ii) Pull out and re-insert firmly all the connections between the computer and the speakers.
(iii) Make sure that only the green speaker connection (jack)Speaker socket symbol to the computer is inserted in the green socket on the sound card or the on-board sound connection. If  the computer sockets are not colour coded, look for the one marked with the arrow pointing out of the sound waves.
(iv) Make sure you have not inserted the jack into a socket on the internal modem card.
(v) Is the volume on the speaker turned to a position which will allow sound to be heard, or is it turned right down?
(vi) Have you connected earphones to the speakers or to the computer's CD drive? If earphones are plugged in, this will stop sound getting to the speakers.
(vii) Click the volume control (i.e., the loudspeaker icon) in the Notification area (bottom right of your screen).Notification area

Volume control

 

Is the volume control muted or turned right down?
 

(viii) Borrow another set of speakers and see if they work.

If none of these tests reveal the source of the problem Go to the top of the column on the right.

Close down the Control Panel.
(v) Test the sound by playing a CD in the CD drive.
(vi) If you still have no sound then the problem may be that the drivers for the sound system are non-existent or incorrect.
(vi) Investigate the drivers as follows:-
Click Start-->Control Panel. Click the System icon. Click the Hardware tab. Click the Device manager button. Click the box containing a plus sign next to Sound, video and game controller. 
If you see any yellow question marks or exclamation marks against any item you have a driver problem. You will need to reinstall the drivers using the Sound card CD or Drivers CD provided with the computer or sound card.

Hardly any volume: If you can just about hear some sound and adjusting the settings does not produce a satisfactory volume, the sound is not being amplified. Check the fuse in the mains socket which feeds power to the speaker or its transformer. Is the power switched on at the mains? If you still have poor volume, the amplifier built into the speaker(s) has failed. You need some new speakers.
