Help with microphone interference

post #1 of 5
Thread Starter 
Or something of the sort. I just got a Zalman mic, during Skype calls the mic was outputting this insanely loud white noise that was on/off randomly. Tested it myself with another computer/account, it's not as loud as my voice, for reference, but it was loud enough to really be annoying. Later on during a call someone else said it started making a deep rumbling noise. I'm in a quiet room, I've tried messing with the volume settings which affects the white noise relative to my voice, tried plugging from front/back no difference.

Could this be an impedance issue? The Zalman mic specs show it's 2200 ohms, I can't find this information for the microphone input on the Realtek ALC889 onboard chip I'm using though. Halp?

Normally happens when you have amplification in your signal source, unless the mic is unreasonably crap. My $2 microphone used to do this, until I noticed I had "+20dB gain" enabled in the device settings. Turning it to 0dB caused it to work perfectly.

Sorry, forgot to include these two for things I've done. Skype had the auto settings disabled forever now and gain affects it similar to how volume does.
