Audio Recording *popping* sound

[Naossoan]

Hi guys,

My sound card doesn't support "what U Hear" or "Stereo Mix" or whatever you want to call it, so I just use Audacity to record my voice and combine them in Sony Vegas afterwards, no big deal.

Anyway, what my problem is actually is MSI Afterburner seems to record a sort of Popping while recording sound. It's a constantly spaced out popping sound. It's not like just a general popping, it kind of makes the normal sounds from the game pop, it's really weird.

Anyone experience this or know of any kind of fix?

Thanks,
