Buzz in mic, more complicated than you think!! Please help

Hi there guys,

my friend has a problem with his mic. It buzzes. We've turned off mic booster/monitoring etc. He uses a Xonar D1 sound card however the buzz is still present when using the motherboard.

We have tried replacing the drivers with unified/older ones. Hes switched his GPU out also. Tried a different mic.

Also there was a point where it stopped buzzing for about a month, and then he updated the drivers and the buzz came back. We tried going back to the driver he used when there was no buzz but it didn't go away.


It gets EXTREMELY bad when playing games, because of that it leads me to believe that it could be power related (the more power it requires/gaming the louder the buzz)

I don't know if this helps but the buzz isn't a constant sound, it changes pitch often. The best I can compare it to is a lawn mower revving higher and low.

Sorry if that is hard to understand.

  1. Have you had any power cables cross the mic cables? I think this is called cross talk. I also found my mouse caused crosstalk through my speakers and sometimes headphones. (Logitech G500, basic speakers, Sennheiser HD 518, Xonar Essence STX.) Making sure the power cables don't cross over or run to closely to audio cables helps. Have you tried Changing input levels and output levels? High output vs low input usually amplifies any buzz/noise, so try to swap it around.

    Edit: As you mentioned higher buzz in-game, it could be elctromagnetic interferance or something. I'm not quite sure how it works or what it is called, but some cards have shields for this (literal metal panels, usually dense lead based). His cards lack of one could also be another factor causing buzz/noise.

    Input levels/output levels in the bios?? and as far as I know the cabling is pretty good. Will have to check with him
  3. also if its electromagnetic interference with the sound card, wouldn't it stop if he used the motherboard?
  4. Actual input/output levels in windows sound settings, so try play with those. Also, check the sound cables for any crossover with power cables. Electromagnetic interference could happen with motherboard sound also.

    Has he got anything in or around his room that could be causing interference or something?

    Oh right! Ah yes we have tried the input/output in windows. And his sound card doesn't have any cables going to it so there isn't any cables to cross over?

    No cables going to it? Okay, if you follow the mic cable(s) (where ever they may be plugged in) do any power cables touch, go near, or anything?

    Have you used the cards audio input? Did you disable the onboard audio in the BIOS?
    If your running a sound card, you would usually disable mobo audio while the card is running.

    Na no cables are touching it. Some cables (like mouse and keyboard) get sort of close to it. But there isn't anything we can do about that as that's where they plug in.

    He is currently using its audio input, we have disabled the onboard sound also. So frustrating!!

    Thanks for helping though man, I really appreciate it !!
