Front audio port noise.

[erratic_gamer]

When i plug in any USB device in my front USB port and use headphones from front audio panel there is a mild noise in the audio signal, is there any solution to this? When i use rear audio port there isn't any. I prefer using front audio port.

It's often an issue due to the poor cables or sometimes poor soldering job done when it comes to front audio ports on most PC Cases. Try going inside the PC Case, isolate the front audio cable and get that away from any other cables; such as USB or any PSU cables. Otherwise the front audio cable is most likely going to pickup digital noise that can be heard when using those front ports.

if ya can try a usb extension cable and plug into a rear USB port on the motherboard itself
\(you can find them even at staples or office supply stores for only a few bucks )

see if the noise goes away .... Bad Motha is right , some cases do suck for front Usb connectors

I wouldn't use USB Extensions, rather instead use 3.5mm audio extensions.

he may have a usb head set \ hence i said usb extention . but yea i o agree with you Sir some solder joints in the front of the case are weak and they do some times make use of unsheilded cables or cheap ones that may pick up noise ..again depends on the case and where the cables lie too

Im using 3.5mm audio extension RN. Ty, i might just get a better case.

A better case rarely solves this issue overall.

Simple open the case and isolate that front audio cable away from other cables like I suggested, and then re-test. It is most likely right now sitting way to close to other cables that carry high frequency through them and then it's bleeding out through the audio cable as static like interference noise whenever in-use. Isolating this cable could perhaps solve your issues and get you back to being able to use your front audio connections.

My current case is very small and cables are very congested, which is why i thought a new case was needed. But ill give it a shot...

do some cable mangemant ..buy some zip ties

you have to really.... if you want decent airflow in any PC case

[Bad 💀 Motha]

I've hardly every found a "need" to use any zip ties unless it's a tight ITX case for the most part.

But yea if you must do this to help bind and separate cables for overall better management / airflow, do it.

I'll try, ty

If this alone does not do the trick, gain access to those front port jack so you can see the solder joints and see if those look ok, maybe a slight wiggle of the jack to ensure it's not a physical issue, such as cracked or broke solder joint. You can buy tape for these kinds of issues as well; such as EMI Shielding Cloth Fabric Adhesive Tape. But with many of them, you must be careful as the outer part might be conductive, so if you wrap a cable with it, you then need to ensure that cable never touches parts of the Motherboard, aside from where it plugs in, such as Front HD Audio Header.

You could also try a ferrite ring/clamp to isolate out any rf/emi interference.
Another trick that sometimes helps with rf is to tie a loop in the cable.

^ That too

I remember many older cases used to have that around front audio / front usb cables inside cases already, I guess makers have grown lazy and cheap over the years.

this is an image of my current situation in the case,

Yea definately I would get a new case. Even cheaper ones now can allow for plenty of good cable management.

Something like Corsair 100R / Spec-02 / Spec-03
or whatever you like that has good look & layout, something similar...

Better CPU Cooler couldn't hurt either, like Hyper212 EVO or X
