iTunes Loud Static Noise

I can by example, do any of these things in isolation, or even together, without any problem:

• Watch a video on YouTube
• Open Adobe Premiere and do some work
• Work in FL Studio
• Open an mp3 in "Groove"
• and yes, Windows sounds playing fine

Again, I could be doing a combination of these things and have no problems either.

So first off, iTunes plays songs beautifully. No problem.

But the moment I open any other sound producing program while I have iTunes open, a scratch noise (like the very old TV's white noise"), but it plays full freaking volume. And every time I get a **** near heart attack.

So a couple of notes

• Fairly new PC still on Microsoft 10, but M-Audio Fast Track sound device probably little old. It uses "ASIO" something whatever have you not.
• I already disabled all enhancements in preferences, and tried various quality settings
• Uninstalled sound drivers, disabled, went crazy
• Regardless the volume of iTunes, Windows, OR my speakers the scratch sound is FULL BLAST!
• The blast is mostly 1 blast, very short but extremely loud. When it's two blasts the second one is even shorter than the first.
• It is ONLY when I have iTunes open, and I am playing music.
• Again, windows sound as well. So if I play music via iTunes and get an "email notification" I KNOW I GOT MAIL ALRIGHT!! I think my neighbours know...
• Apart from Windows sound, it seems to happen only with programs opened AFTER iTunes were opened. If I had Premiere open BEFORE iTunes it's not a problem.

Again...The ONLY time I get this scratch noise is when I have iTunes open playing music already, and I OPEN any other sound producing software or platform. It's just ON OPEN of whatever other software I open.

I have also learned in trying to isolate it, if I keep FL Studio open, the problem seems to disappear.

I can only "guess":

• iTunes somehow "hogs" the priority of devices, and possibly with ASIO, there is a latency for the program I try open, causing this horrible noise
• Because it seems to disappear when FL Studio is open, I think it's also got something to do with FL Studio ASIO support architecture...

But no other programs or software or combination thereof creates this problem. It's only when playing music on iTunes, it actually does not make sense!!

It's a freaking odd ball, my workaround now - keep FL Studio open while listening to music on iTunes, in case anything else may way to use sound on my PC...
