Could my Sound Card be the cause of static (audio) build up?

[NovaInfuse]

Hello Everyone!

I hope I've put this in the right section; I couldn't really find a topic related to audio/sound that was for computers, so thought it would fit into the component section.

I've recently swapped back from using my in-built audio on the motherboard, to an Asus Xonar DX, with my Roccat Kave 5.1 Headset.

I've been told that when using VOIP services, such as Skype, Mumble or Teamspeak, that there is a large static noise in the background (been told by one person it sounds like I'm sitting next to a bi-plane.)

I've done a test call on skype, and it is indeed there in the background (it gets louder and louder, but when I speak/make a sound it drops the static back down to a minimum).

I recently tried to test this on twitch.tv, examples of which can be found here:

When I look at the levels on my streaming software, such as Xsplit or Open Broadcast I can see the levels on the mic showing, even when I am muted or not talking. This is also the case when I remove all sounds from my room (bar my fans, which are quiet and do not make the noise on the mics). Furthermore, when I look at the mic in Control Panel - Sound, I see no change in the levels at all.

It is the only device, audio related, plugged into my computer. I have speakers, unplugged, sitting next to it.

My specs are:
Windows 7 64 Bit
Nvidia GTX 570
Intel Core i5-2500k CPU
8GB Ram
Can't seem to find my motherboard in the Dxdiag, but if I recall, it is an asus.

Thanks in advanced!

Static is caused by telecommunications interference which could include things like a usb modem, iphone or simlar phone type, amplifier, or an electrical ampliance too close to the speakers. Make sure the speakers (and amplifier) are more than 3 feet away from those devices. A cooling fan or air conditioner or fan heater can also cause similar interference.

Hey, thanks for the reply!

I've removed everything that could be causing that in my room. No phones, speakers are out as well as my fan but the static still prevails. Is there anything else that could be causing this to occur?

It could be your PSU... Ive seen similar issues in the past. Try reseating the DX, and finding older drivers. You can always get an external usb DAC (most have some decent amps in them), and perhaps try another mic.

If you are using a sound PCI card then you have to disable onboard audio in the bios even though it is temporarily disabled by the OS when a sound card is added.

Check the Xonar ports and that your mic and line in are correctly selected.
