I've got a weird sound problem on my pc that makes seemingly no sense! Everytime I open a program (or in some cases, do somethign within a program, for example, load a new map in Team Fortress 2) a faint fuzzing/static sound comes up through my headphones. The weird thing is, if I open up the generic windows sound cotnrol thing, and either unmute or mute (it doesn't matter which) the Auxilary setting, it fixes itself. I can even remute/reunmute it and it goes away, UNTIL I open another program/load another level and it kicks in again!

Are you using on board sound (motherboard)?

Does it only happen with headphones?

Do you have the headphones plugged into your speakers or into some port on your computer directly (is it a front installed port or on the back?)

Static sometimes comes from a loose connection so, assuming you haven't done so already, make sure the connection to the PC is ok and also check along the wire from the headphones to see if it's starting to split anywhere. I know that doesn't really go hand in hand with the symptoms you're describing but I'd check just in case.

STICKY KEYS! lol jk...u may want to check connections first, may be loose or damaged somehow. How old are your headphones?

I'm using a soundcard (sound blasty audigy, I believe? Not totally sure), and the headphones are plugged directly into the card.

Ok, checked with my monitors speaker and it has the same symptoms. And my headphones/monitor are both pretty damn new.

Did this start when you changed monitors?  Is it possible the monitor is sending out interference, possibly when changing screens (such as displaying a white or black screen)?

I guess it could still be a software problem, if you really have an Audigy that is a very old card, I remember having problems in Counterstrike Source with one, but I doubt they'd crop up all of the sudden.

The only other thing I was thinking is interference coming from other parts of your computer and interfering with the output on your card directly.

Come to think of it, it did start around about when i got my new monitor, but it's far enough away from my soundcard/headphones that I can't imagine it being the cause. Maybe, though.

The static starts when the loading bar gets about halfway in TF2, or when I open up the options. It happens in a lot of other programs as well, but they're the times I really notice. And yeah, the second I check the box it stops.
