Windows 7: No sound on my Dell Inspiron running Windows 7 64-bit

Had sound this morning but I noticed that when I listened to podcasts my speakers would not let me adjust the volume. Now I have no sound after downloading and installing Realtek audio several times from different sources, the last being this forum. Nothing seems to bring back the sound - any ideas?

Go into your sound properties, is headphone selected instead of speakers? Had this happen to me once.

No, I've never used headphones and my Realtek Audio just lists speakers/headphones - can't separate the two. Thanks for idea though!

Click on the Sound icon in your notification area. Select Mixer. What is the volume set to for whatever software you're using to play audio?

sound at max all around

If I did that they'd be blowing me out.

In Control Panel, Sound, click on your speakers and select Configure. Do you get any test sound with the different available configurations?

No, but I do have a curious problem. In my Realtek Audio properties under sound it lists the location as Location 2, and when I go into Levels under Speakers/Headphones Properties it only shows one of those speaker icons for the Microphone, Rear Pink In and Rear Blue In. I don't know what those are, but I do not have an icon for Center, Subwoofer, Rear, or Front.



So maybe I need to switch to Location 1 ??? How do I do that?

In the Control Panel, Sound, when you click on Speakers and select Properties, which jacks are shown as connected? Are these the correct ones per the speaker manual? Ordinarily, the color of the speaker plugs are the ones you use. I don't know what motherboard you're using but, I'm not familiar with a pink speaker jack. On my motherboard, pink is used for the microphone.

Also, where do I go to get to the realtek audio properties? I'm using a sound card.

I just looked at the specs for your system-

Back Panel Connectors - Dell OptiPlex 780 SFF Setup And Features Information Tech Sheet [Page 4]

It seems you would use the green (6) and blue/pink (7). It's kind of convoluted since it (7) shows blue/pink but I have no idea what it means.

I have 3 colors in a row Pink - Green - Blue. I have a green jack and plug into green, I don't know what the pink and blue are for I've never used them. But somehow the Realtek Audio has disabled my usable green main sound jack and is putting sound through the "Rear Pink In" and "Rear Blue In" channels and "Microphone". I have no audio icon for my "Center", "Subwoofer", "Rear" and "Front" (last two for balance). I'm using Harman/Kardon speakers and subwoofer. All was working fine a few days ago.


If you have an idea how I can get Realtek to switch from Pink and Blue to Center and Subwoofer? I'm lost and don't want to screw up my system further. I've installed the latest Realtek driver at least 3 times (I know, I know, don't duplicate a failure hoping for different results - ha, ha). Any help is greatly appreciated!
