Odd, un-mutable background noise

[otterotterotter]

So I recently build a budget gaming PC (http://pcpartpicker.com/p/LDNK23) and for some reason I hear this constant whining and beeping noise through whatever headphones/speakers I have plugged in to the front panel audio connector. The noise is unaffected by adjusting or muting the volume.  I've made sure the HD audio cable is plugged into the motherboard correctly and securely. If needed I might be able to provide an recording of the sound.

constant whining and beeping noise may be cause by poor grounding

 

check all your motherboard power connections especially the 24 Pin mobo connector

Try plugging your headphones/speakers into the back panel. If you still hear the noise even when plugged into the back panel audio, I would assume it's a ground/amp issue.

Alright so I made sure all the motherboard power connections are plugged in properly. Still have the noise. Also, because there is little room to tuck away the power supply cables I'm not using, I kind of stuffed them into the empty space where the optical drive would be mounted. I assume this wouldn't be the issue since these cables are not plugged into anything.

I just noticed the noise reacts when I move my mouse around. It also gets more intense when I open up a game or graphically intense program.

Sounds like interference issues.

Poor filtering/shielding on amps can cause this; they pick up the noise, then amplify it.

If you have a microphone plugged in, try unplugging it and see what happens. I have the same experience as you when I plug in a guitar amplifier into my computer's microphone 3.5mm port.

Well my IEMs (Astrotec AM-90) have a built it mic. Would an audio splitter (ex. http://www.amazon.com/gp/product/B0058DOWH6/ref=s9_simh_gw_p23_d0_i5?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=1S8RAA6DNN2S27A00PY2&pf_rd_t=101&pf_rd_p=1688200382&pf_rd_i=507846) solve the problem?

I don't think it would work because audio splitters don't modify the audio signal in any way, I think.

 

Could you try going into your audio control panel - for me it's called 'Realtek HD Audio Manager' - and go to the microphone settings. Look for 'Recording Volume' and 'Playback Volume'. Mute the 'Playback Volume'.
