Windows 7: Sound and Graphical Error When Alt Tabbing From Full Screen Game

Sound and Graphical Error When Alt Tabbing From Full Screen Game

Getting distorted (cracking/popping) sound and poor FPS/screen tear after switching application from a full screen game via the taskbar and via alt tabbing.
The only way to rectify the issue is by restarting the PC as reloading the game will semi fix the sound issue, but limits my FPS to 30 and will cause the sound to slowly deteriorate to how it was before.

It mainly happens when I have a full screen program while watching a Stream/Video on my second monitor and I switch program through the aero feature in the taskbar/alt tab pop up. Sound goes to shit, then the frame loss kicks in a second later.

I assumed it was an issue to do with the aero application preview feature, but I'm not 100% sure. I've disabled it by using the classic theme which I've been using for the past 2 days and things seem to be alright.

Hardware:
-AMD 1090T
-m4a89td pro-usb3
-8gb DDR3 RAM (4x2gb sticks)
-MSI GTX 460 Hawk
-ASUS Xonar DX

I can manage without aero so I'm able to actually use my PC, but I'd rather fix the issue than ignore it.

Thanks in advanced.

tl;dr in title.

Almost all games hate being Alt-Tabbed out of, a lot of them simply crash the moment you try it. It's not something you can fix, at least no way I'm aware of.

It only occurred around a week and a half ago, prior to that I never had any issues resembling the ones I'm describing.

The only thing that has changed in my setup since then has been a new monitor to replace my old primary that I moved to my secondary, meaning I changed from two dvi screens to one dvi and one hdmi.

I've tried going back to my old setup to see if it would fix anything, however no luck there.

Make sure you have the latest graphics card drivers for your GPU.

I know this isn't fixing the actual problem but if it doesn't occur when Aero is off, why not just turn Aero off when playing the game(s) that give you the problem?
Go to the particular game(s) exe right click it/properties/compatibility/check "Disable Desktop Composition". This will turn Aero off while playing the game but it will come right back on when you close the program (game).
