Buzzing noise with new headphones.

[zetaslow]

I got a new pair of headphones today and after awhile I noticed a quiet buzzing noise when I move my mouse around or type on the keyboard, soon I heard the noise without any user input until I restarted my PC then it was just buzzing when using my mouse and keyboard.

I tested several headphones and heard no noise however these new ones are better than my old ones, I've also tested them on my brother's PC and heard no buzzing.

I'm using my onboard VIA HD Audio driver(up to date). I still hear the noise even if I disable all audio devices.

Motherboard is a Gigabyte M4A785TD-V EVO. Is this what's to blame?


Rig, although I can't help but think most of this wont help with this.
OS: Windows 7 64
Mobo: Gigabyte M4A785TD-V EVO
GPU: Radeon HD 5850
CPU: Phenom 2 x4 925
No sound card
Ram 6GB
PSU: Corsair TX 650W V2

EDIT:
No wireless mouse/keyboard

Plug the headphone into the rear GREEN speaker jack and see if you still get the noise. If its OK there, there is something wrong either with the front panel assembly in the case or possibly the wiring or how its routed to the HD Audio connection on the motherboard.

 

[zetaslow]

It's already plugged in at the back. The front is unusable, if the jack moves at all when it's plugged in at the front you get your ears attacked by a burst of this horrible grating noise. Sounds like if you twist the jack around when plugging it in it sometimes makes that grating noise.

you might have 2 devices hooked up to that channel port it happens when you have aftermarket sound card or some sort of hardware

I would get the MB manual and check all connections from the case to your board if not resolved it might be a bad chip for your sound device that fused to the board

Got access to a stereo or another machine zeta if the buzzing isn't there using them then there is a problem with your audio set up mate.

As matter of curiosity what frequency range is this new set compared to your old ones?

The other thing would be to know what sort of drivers the headphones are using voice coil or piezo?

 

[zetaslow]

No buzzing using any stereos or anything.

Frequency range is 10Hz-22kHz, 40mm neodymium driver and it's piezo.

EDIT: Old headphones had a frequency of 14-20Hz

Disconnect the front panel headphone jack connector from the motherboard. It could be causing feedback.

Also, do you get the noise with regular PC speakers plugged in?

 

[zetaslow]

Disconnected the front jacks and I can still hear the noise. I can't even tell if the speakers get the buzzing because they get a buzzing/hissing noise when turned on even when not connected to anything.


Also added the frequency of my old headphone just above.

 

[fireberd]

If the speakers buzz without being connected, I wonder if there is an AC power line problem that is causing all the "buzzing"? Is the AC receptacle that you are plugged into properly grounded? (and properly phased)? Any way to move the PC to a different AC Power line feed (and phase)?

I am thinking along with fireberd that maybe you may have a "ground loop" within the machine.

I know from the past with old stereo systems for example if one had a power circuit where you plugged in one device and because he ground was connected to the chassis and it in turn was connected to ground at the input / output socket that a second device that was similarly grounded via it's supply it caused a loop via the connecting leads - any extraneous hum from the ac supply would be picked up by the loop that was created. I used to cure this by disconnecting the ground to either the output or input of one device so interrupting the loop, there were other ways of course.

But this was purely a mains frequency hum - 50Hz and I don't know what frequency you are experiencing via the phones. But similar situation might exist though it is hard to imagine.

Even simpler would be to try a different brand of phones, and get your money back for the ones you have now, at least that is what I would do.

I'll contact the website and explain the problem to them. Hopefully they will cover the return shipping as it cost me £10 shipping to get these.

I tried plugging my speakers in different rooms and they buzz no matter where I plug them in. Just rubbish speakers I guess.
I've also tried plugging my PC directly into the wall and I'm still getting buzzing.

 

[fireberd]

Do you have another headset or set of speakers that you can try. If nothing else can you borrow them from a friend so you know which is the cause - the PC or headset. When you try again, lease the "bad" buzzing speakers disconnected and just connect the headphones directly to the GREEN speaker jack on the back.

 

[zetaslow]

I have tried 3 different headphones now and none of them can hear the noise. Although the frequency range isn't the same as these.

I tried my brother's and I think his has a higher frequency range than these new ones but they don't go as low. They never picked up anything either. I have no headphones that go under 14hz.

I can only plug into the back for now as I've left the front USB and jacks unplugged. never use them anyway.

 

[fireberd]

Headphone frequency response is probably not a real issue. If none of the other headsets get the noise, I would suspect the headset you have is the problem.

Yep have to go with this one fireberd has to a be bad batch they put through.
