Question : Problem: Video & Audio Microphone USB Device :: Hissing Background Sounds on Playback :: 4:43AM!

Hello,

I just purchased a Windows Lifecam, and it all works perfect, but I cannot get rid of an annoying hissing-bumpy ringing tone after recording any sound.

I've tried:

-- complete reinstall (several times)
-- Tried all USB ports (in and out of my video card)
-- Tried all variation of sound/volume adjustments
-- Search google relentlessy but could not find anything valuable!

Notes:
-- hissing sound stops when the volume is off or muted
-- The hissing is not caused by voice. its the same if i just let the mic site silent.
-- hissing is slightly uneven and rigid sounding
-- do not have this issue when another mic is plugged direct into the mic port
-- It's 4:43am now
-- Hissing only happens on playback of sound file
-- hissing also occurs when i use Windows sound recorder (and through the same mic)

This device is a USB that runs video and sound.

Does anyone have any ideas?

Well, since I found out what the problem was I will share it.

Be ready it's complex. It is very complicated:

It was all caused by the lights in my office. That's it. Fluorescent and standard bulbs both caused the hissing. Lights off == no hissing : )

Hope my solution is as easy to understand as the problem itself.
