Static/Coil whineish sound when not playing any sounds

post #1 of 9
Thread Starter 

Hello!

 

When I'm not playing music, I hear staticish noises, which increases when I, for example, use the mice or the keyboard.

Its only when I have the volume knob at higher levels. But still, as the HiFi guy I am, I wanna get rid of it.

Is this possible? Is it bad motherboard implementations or would I maybe need a converter?

You don't say what your setup is, but I'm guessing you are using your PC's onboard sound? If that's the case, then an external DAC can make a massive difference not only to the background noise, but also to overall signal clarity, detail level and spatial precision. Most motherboards have pretty basic sound support as providing high quality audio output increases production costs, takes more real estate on the motherboard, and is not really a mass market requirement. 

 

You may also need to upgrade other audio components, as a DAC itself will only provide higher quality line output.

My setup is in my signature?

Headphones: Audeze LCD-2

Amplifier: Schiit Mjolnir

DAC: Arcam irDAC

 

I'm using USB.

 

Yeah I have a cheap motherboard (Gigabyte UD3H Z77)

In that case the symptoms would point to a ground loop issue. I'd start with trying a USB isolator. Check this link - it is frequently mentioned and recommended, although I have no direct experience with it.

If it were a ground loop, it would be a solid tone, not static. Possible noise floor, output going out.

Oh, how can I fix this ?

If it's the output then that would need to be replaced. It should be a pretty easy fix if your comfortable with soldering.

Replaced as in I can RMA the motherboard?

Possibly, I meant more the DAC though.
