Windows 7: Static noise being transmitted from microphone, but don't have one.

Lately I've been getting yelled at when gaming because I accidentally hit my "push to talk" key sometimes even though I don't have a mic plugged in, whenever that happens people seem to hear a really loud static-y crackling sound coming from my "mic."

Now, I've been trying to use HLDJ with Team Fortress 2, and I'm hearing the same sounds whenever I set the game to voice playback and try to play an audio clip.

The recording device that my sound settings say I'm using is the default "Digital Audio" running with that generic "High Definition Audio Device" driver.



I tried using Audacity to record the sound from my mic, and the audio meter in the program says that all the noise is coming from the left speaker, which makes me think that something went wrong with the driver.

Any suggestions that might fix this?

First thing, fill in the "My System Specs". We can't really say as we don't know what hardware you have.

I ended up installing the newest Realtek drivers, that fixed basically everything. No need for any more help, thanks anyways.
