Dell Precision 690 Workstation -NO SOUND

What did you add or remove prior to it not working? By the way, I do not see any Win7 drivers for this model. What sound driver did you install when you loaded Win7?

First, thing, assuming it's not muted, check the Control Panel/Hardware and Sound and finally the Sound panel.  Make sure your "Speakers" are set as the Default Playback Device.  

If it was working OK and nothing was changed or added, the System Restore function MAY get your sound back.  System Restore can be accessed from Start/Programs/Accessories/System Tools.  Choose a recent restore point when it was working properly.  System Restore will not delete any user data or e-mails.

Working the above. I will get back to ya guys.. Thanks for the quick response.... Stay Tuned.

The rear jacks are mounted to the motherboard and realistically are not replaceable and I doubt that the physical jack is the problem. 

If you have something plugged into the front headphone jack, the rear GREEN speaker jack is muted. 

Just plug in the speakers to the rear green speaker jack.  Then go to the Sound Panel, playback section.  Click on the Speakers to highlight that and then click on the Configure Button.  Make sure your speakers, e.g. stereo speakers, are set and then test the speakers in that panel to see if you have any sound.

Ok... This is what I did...

I did a restore point and I have sound BUT.... I do not have sound from the rear jack (green / blue). I then plugged my speakers into the front headset jack in front of computer...then is sound.

I did check the drivers and here they are:

The speakers are set as default.

Seems I have the most up to date driver.

It seems there is a hardware problem from the rear jack of the computer.

Is there replacement parts that can be replaced .. for these jacks blue and green are located on the motherboard to the rear of the computer??

What do you guys think?

Thanks in advance.

Still NO SOUND through the back sound jack (green) via speakers. Sound does go through the front head phone jack..

Hi John,

My Dimension 9200 developed a similar problem, after a house move! No change in configuration of the PC whatsoever. The speakers simply refused to work when connected to the green rear speaker jack. I solved the problem by plugging the speakers into the front headphone socket. My contention is that its a dodgy connection or built in obsolesence perhaps like the DVD drive on my Dimension 9200 PC that stopped working three days after the warranty expired? I had a similar problem on my previous house move, with the speaker connection, and then the problem was rectified by twisting the speaker connection around in the rear green jack until I got some sound. This time though that did not yield any results apart from some loud humming in the speakers, until when pushed home no sound at all.

What helped me was the post about checking to make sure nothing is muted.

Even if you don't have mute active, you may still have stuff muted without knowing.

Double-click the speaker in the task bar and bring up the master volume.  Check that nothing is muted.  If "Wave" is muted the headphones won't work.

Usually when you press a mute key on your keyboard it will "mute all".  But sometimes "wave" can become muted by itself which prevents headphones from working.
