Logitech LS-21 2.1 Speakers - Answered Questions & Fixed issues

Go into control panel, then go to device manager and see Audio devices. Check to see if your Realtek is listed as your default audio device. If it isn't you have to add hardware and add the audio device using your setup disk that should of came with the computer. If the audio device is set up and working in device manager then check your cable from the mother board to the jack on the audio out that is mounted on the mother board. Finally if non of that works see if you can borrow a set of speakers to try to see if they work with your setup.

There are 2 volume controls on the audio output in windows 7. one is the system volume the other is the device volume. make sure that they are both at full and then control the sound volume on your speakers.

defective check out backside membrane of speaker or better send it to service center

Try using an earphone on the system, if it works properly ( that is if the sound is good and normal) than probably your sound IC needs to be replaced as it is wearing out.

Hello
Try going to control panel,audio,settings.Make sure your speakers are set to 5.1 surround sound.

Next if there is software for these speakers or your audio device be sure it is also set for surround sound.

YES YOUR SOUND DRIVER IS NOT ISTALLED .
YOU ALSO USE THE INTERNET YOU DOWNLOAD THE NEW VERSION OF REALTEK SOUND AUDIO DRIVER AND THEN SOUND IS OPEN.

There is no additional software for your speaker system I went to logitechs website and checked for you. Here is their link to your speakers either click on the link I am sending you or copy and paste it into your web browser.

Your only adjustment to your speakers is if you right click on the speaker and choose what you want to adjust from the pop up menu that comes up.
