Need Help with Speaker Connectivity Issue

[JanJonDijonMustard]

I recently purchased the Logitech Z623 speaker system for Christmas. I wanted to use these as a sound system for my self built PC currently running on Windows 10 with Realtek Audio as my sound manager software. The problem itself is very odd (at least to me, I couldn't find a similar instance in any forums). When I try to use the speakers they don't output any sound but are seemingly hooked up to the PC just fine. Realtek recognizes them, they are in the sound manager options and everything. I even get the little bars on the sound slider when noise is supposed to be made and when I press the mute button in the sound slider the speakers even make a distinctive pop as if they were being muted. The speakers themselves work fine. I plugged them into my andriod with an aux and they played music normally. The speakers also make a slight high pitched whining sound while on, but I'm not sure if this is part of the issue. My best guess is that it is either a software issue somewhere or a problem with the 3.5 mm jack socket on my motherboard back panel, honestly though I'm not experienced enough to diagnose the problem. Any help with this issue would be greatly appreciated.
Here's what I've tried so far:
1. Restarting the computer/unplugging and plugging the speakers.
2. Making the speakers the default the device in Realtek audio
3. Plugging them into the front panel (this actually makes them play but only the desktop speakers, not the subwoofer)
4.Rolling back the sound drivers in device manager

One thing to do is to try either earphones or another set of speakers in 3.5 mm jack socket on your mother board. At least confirm the jack to be or not to be a problem.

Second, plug everything in as you understand the connectivity to be and work your way through gently wiggling and move the plugs in an out. Sometimes an improper fit (does not take much) will cause such audio problems.

Third, double check all the connections and settings. Sketch a quick diagram as a guided and then go over all internal, external, and volume controls (via a right click on the speaker icon) and see if anything turns up.

Just plugged in my headphones to same socket, they don't get any sound either. Does that mean my motherboard is bad? How can I fix this?

Well if everything else is working then the motherboard is probably okay - just the socket is/maybe bad.

From the outside with the computer off look inside the jack for dust bunnies, hair, paper scrapes, debris in general that may be preventing a good clean connection. Clean gently - again with power off. Ground yourself to avoid static discharge also.

Next open the case if you are comfortable doing so (or, if not, get some help) and just visually inspect the area around the socket as best you can. Do not touch just look. If all seems okay, power down, and then gently touch and wiggle. Should not be any looseness around the jack.

Pay attention to any internal audio cables - make sure that they are secure and tight.

That unfortunately didn't solve the problem. I'm not sure what gives though. My motherboard panel in the back has two lines of 3.5mm jack inputs. The first one is gray red and black and the other is blue green and pink. I thought the gray one is the one i'm supposed to plug it into but that one has no sound what so ever and when I plug it into the green one, the other that I thought might work, it one uses the two top speakers and not the subwoofer. I'm so confused.

Yes it is confusing. But with some additional work and research via persistence you might find a solution or that it simply will not work as intended.

Get your motherboard guide/manual and identify each colored jack on the panel: i.e., color and purpose. Also look for any internal audio connectors that may be necessary.

Which socket is not working? Or fully working?

Also "google" 3.5 mm color codes and see which/what standard (if any) that your motherboard is using.

Also take a look at this Tom's Hardware Forum link:

If there is a proveable working setup and it still does not work then, since the speakers work correctly elsewhere, the motherboard audio is suspect. You may need to purchase an audio card and disable the onboard system.
