Well......This is new, my ability to record has been hampered by this buzzing, I don't know what's causing it and it's been happening recently, I have tried various microphones and sound drivers so I doubt that it is both but does anyone have any idea what else may be causing this problem?

Here's a sample the mic boost just makes the buzzing more clear if you need to hear it

and no my voice becomes inaudioble with the mic boost off

BTW. I am using the onboard sound of the ABIT NF7-S V1.0

Well, it seems to happen on some cards... like my C-media PCI one :s
No driver or any other changes could fix it... the only workaround was to use the PCI card as sound player, and my onboard one as recorder :-(

So my advice is to buy a cheap but good quality sound card, any recent Sound Blaster (Creative) card will be fine, don't aim for a high-end one if it's just for internet chat and games ;)

EDIt: You got a buzz, maybe it's a problem with power supply :I
My problem is a constant high-pitched noise :p

I know, but... good cards both record and play correctly. Onboard chpisets are often pure crap, least known brands also make crappy PCI cards, that's why I advise you to buy the cheapest SB you can get from Creative

Seems like your microphone input is picking up low frequencies, not cutting off/filtering them as it should. It could possibly also be your computer picking up/generating frequencies from fans/harddrives etc. Another source for low noise/humming may be a bad grounding or nongrounded wallsocket. Possibly I missed something, maybe others can help.

Look at the comparision mine vs yours in the pic below, notice how mine cuts off the low frequencies and how it is pretty evenly balanced. I had microphone boost enabled aswell.

Edit: Also make sure you are using mic-in and not line-in as they are different inputs.

I am using mic in and I have tried it with various microphones and even some pro grade noise cancelation and directional microphones and it still reports the same thing even if I use a dummy mic (a audio cable connected to a unused speaker rather than a mic) the buzzing is still there

edit:my +3.3v rail is showing 3.1-3.09 V instead maybe this has something to do with it

More Edit: Now my speaker are also buzzing

Even more edit: Just tested my PSU in another computer and it seems to work fine there

As Mr.Killjoy said, if you can, try borrowing another soundcard and see if it works better. By the way, what kind of sound(card/device) is it anyway, some onboard ac97/99?

Lento AC97 is what I use for recording, and it works fine, better than my PCI card :p
I guess that's random :I

Weird, I have no problem with it :s
Update your mobo drivers... but I guess you already did it

it only happens with recording not playback

It wasn't interference form the PSU, I swapped it for a old PSU that I just modified with 3 layer grounded aluminium foil shielding and the problem didn't change
